Analysis of Gear Height and Strength of Gear and Gear in Reducer
Link: gearbox parts    2016-01-26
... The reducer prototype was tested on an open test bench and loaded with a hydrogenerator. The industrial gear boxes meshing quality and the reducer cleanliness were tested by the no-load, full load test and overload test of the gear unit. The results show that this reducer has the following salient features: the size of the gear teeth are higher than the same parameters of the involute gear is small, the bending strength greatly improved.In the process of hobbing, it was found that the hobbing chips were smaller in curl (and the chips produced in the generally involute gear hobbing were burr-like, resulting in a shape similar to that of the chip), indicating that during the hob cutting The resulting crust curvature is large, the deformation is small, the chip flow is free, the friction between the chip and the tool is small, and the wear of the hob is obviously smaller than that of the ordinary gear.At the same time, due to the same modulus in the conditions of the involute point line meshing gear tooth depth shallow, cutting the amount of ordinary involute worm gear speed reducer than the same type of small, so less time consuming, and more conducive to reduce the hob The The tooth contact area consists of a slanted straight line and a contact surface, moving axially during operation, forming an oil film in the axial direction, adding a unique tooth profile, and its contact strength is greatly improved. The meshing gear has an end face coincidence degree and an axial coincidence degree, so that the coincidence degree is large, the transmission is smooth and the noise is low. View Details

From the origin and history of hardened gear reducer

... From the hardened vertical gear reducer of the origin and history, to see the hardened gear reducer career; from the hardened gear reducer career at that time the environment, look at the primary strategy of professional competition. Although many of the advanced elders of hardened gear reducer continue to be available, but they are not dealt with invisible title, all hardened gear reducer device, there are some equipment exposed to the door, hardened gear reducer is damaged The possibility must exist, the security title has been threatened.A professional lack of brand awareness naturally difficult to have well-known brands. It is understood that the lifting of the hardened gear gear reducer career this situation has a turning point, Wenzhou 8 annual sales of hundreds of millions of hardened gear reducer wholesale has formed a collective, one of the intent is to build China's hardening Tooth gear reducer professional aircraft carrier. The first is that China's hardened gears electric motor speed reducer Hardened gear reducer technology content, quality and price significantly lower than the advanced level of advanced countries in developed countries.2012 years have passed, this year, on the hardened gear reducer industry, there are sad and sad, happy is the 18th of the industry for the industry to bring a lot of indignation, the future of the road more bright.To promote independent innovation, the implementation of brand strategy, forward hardened gear reducer added value of the current lack of professionals has become a constraint to China's hardened gear reducer career to further develop the bottleneck, which is bound to affect China's hardened gear reducer Professional world competition. To deal with this title, you can take the road between internal development and external introduction. Cultivate and introduce hardened gear reducer professionals, to enhance the intellectual capital elements of China hardened gear reducer career for labor-intensive occupations. Energetically play the support of the government to support the effect of hardened gear reducer career to carry out a good environment. Vigorously carry out hardened gear reducer industrial clusters, to create hardened gear reducer industrial chainReal China hardened gear reducer brand career is very standard, if any hardened gear reducer wholesale station out for the professional standards to do something, it will become a professional leader, such as : A brand of hardened gear reducer wholesale lead, the development of professional standards may be drafted to carry out professional white paper, about the direction of career development, such action can not only improve the hardened gear reducer wholesale brand reputation, but also has Public nature, will make the hardened gear reducer wholesale into a professional leader will be very large. Brand promotion professor Luo Baihui that the positioning of the brand is based on the needs of the shopping malls to take advantage of the advantages of positioning.Take the collective or joint hardened gear reducer wholesale road, composed of several large hard tooth gear reducer wholesale collective, guide the career to develop, invent the individual brand, active involved in the world competition.Strengthen the hardened gear reducer wholesale internal management, and constantly improve the production technology, lower production costs, forward economic benefits. Hardened gear reducer has become a series, standardization, type of standard completely, hardened gear reducer quality is not chaos, part of the hardened gear reducer in the world shopping malls have a certain competition.

How to solve the situation of early pitting of reducer?

... How to solve the situation of the early pitting of the vertical gear reducer. Pitting must be related to lubricants, and it is also closely related to the material of the gear unit. Usually the use of a process will have a certain standard. Another point is due to bad gear caused by local overload caused by the local overload of the gear so that the actual contact stress greatly exceeds the allowable contact stress of the gear material, and some gears do not reach full teeth long contact or only in the teeth The end of contact, and even diagonal contact. The following by the Shanghai Jin Chang reducer to elaborate for us in detail.First, the impact of materials and processing specificationsThe choice of gear material is correct and whether the use of load matching, heat treatment hardness selection and matching, but also affect the early pitting reasons.Second, the impact of lubricantsDue to the irrational lubrication of the gear transmission and the choice of the lubricant is also the reason for the impact of early pitting. To prevent reducer gear early pitting pathways:(A) gear reducer drive reasonable lubrication and select the appropriate lubricant.(B) to improve the combined worm reducer gear installation accuracy, to ensure that the gear contact accuracy.For the center-driven reducer, if the assembly and installation, without a good investigation, there may be left and right two-way drive is not synchronized, are loaded effect is poor, in this case, the side of the transmission gear may not bear Load, while the other side of the transmission gear is overload (up to twice the design load), which is likely to cause the tooth surface to produce progressive early pitting.

What is a gear reducer?
Link: bevel gear sets    2016-01-20
... Gear reducer is the use of gears at all levels to achieve the purpose of speed. By the various gears, such as the use of small gears to drive a large gear can achieve a certain degree of deceleration purposes, and then use the multi-level structure, you can greatly reduce the speed.Gear reducer is generally used for low-speed torque-increasing transmission equipment, the motor. Internal combustion engine or other high-speed operation of the power through the reducer on the input shaft teeth less gear meshing the output shaft on the gear to achieve the purpose of deceleration, Ordinary reducer will have several pairs of the same principle gear to achieve the desired deceleration effect, the size of the gear ratio of teeth, is the transmission ratio.

... The drive of the reducer drive system includes the periodic excitation caused by the machining and assembly errors of the transmission gears, cycloches, gears, worms, worms, screws, shafts, etc. of the transmission parts. Torsional vibration and shock excitation, and random excitation due to fluctuations in the grid, transient instability of the transmission.The reducer is a kind of independent component which is composed of gear transmission, worm drive and gear-worm drive enclosed in a rigid shell. It is often used as a deceleration transmission between the original and the working machine. In the prime mover and the working machine or between the implementation of the matching speed and transmission torque between the role of modern machinery is widely used. View Details
