Bevel gear single stage transmission ratio can reach 6 or 8 or above, the transmission efficiency is generally 0.94 ~ 0.98.1) the design, manufacture and installation of the straight teeth and helical bevel gear are simple, but the noise is larger, which is used for low speed transmission (<5m/s); The transmission power of the straight bevel gea... Bevel gear single stage transmission ratio can reach 6 or 8 or above, the transmission efficiency is generally 0.94 ~ 0.98.1) the design, manufacture and installation of the straight teeth and helical bevel gear are simple, but the noise is larger, which is used for low speed transmission (<5m/s); The transmission power of the straight bevel gear transmission can reach 370 kw, and the circumference speed is 5 m/s. The helical bevel gear drive is stable and the gear load capacity is higher, but the manufacturing is more difficult and the application is less.2) the curved tooth bevel gear has the characteristics of smooth transmission, small noise and large carrying capacity. The spiral bevel gears drive smoothly and deliver power to 3700 kw, and the circumference speed can reach more than 40 m/s.It is divided into straight bevel gears and spiral bevel gears View Details

It also has the form of point erosion, abrasion, adhesion and the fracture of worm gear box wheel. The surface erosion of the tooth surface and the tooth surface of worm gear reducer are the most common, and the adhesion is also common. The emergence of the failure is mainly due to the relative sliding speed between meshing tooth surface is larger, especially in cylindrical worm drive the lubrication Angle is too small, 8 formation pressure of oil film, so on caused by low efficiency and high temperature.   In addition, due to the lack of stiffness of the worm and the error of fabrication and installation, the above failure forms can also be caused. The fracture of worm gear speed reducer tooth is caused by the thickness reduction of the teeth after the gear tooth wear, and the error of installation caused by the large deflection. In conclusion, worm gearbox tooth is the weak link in both of the worm gearbox tooth structure and the mechanical properties of the worm gear. View Details

Ideal reduction ratio calculation formula: reduction ratio = servo motor speed / reducer output shaft speedTorque calculation: For the life of the gear unit, the calculation of torque is very important, and pay attention to the maximum torque value of the acceleration (TP), whether the maximum load torque of the reducer.Selection of the Pc Helical ... Ideal reduction ratio calculation formula: reduction ratio = servo motor speed / reducer output shaft speedTorque calculation: For the life of the gear unit, the calculation of torque is very important, and pay attention to the maximum torque value of the acceleration (TP), whether the maximum load torque of the reducer.Selection of the Pc Helical Gear Box model and its precautions: Applicable power is usually applicable to the servo model on the market, the applicability of the reducer is high, the working coefficient can be maintained at 1.2 or more, but in the selection can also be their own Need to decide:A. The output shaft diameter of the servo motor can not be greater than the maximum shaft diameter on the table.B. If the torque calculation work, the speed can meet the normal operation, but the full output of the servo, there is a lack of phenomenon, we can drive on the side of the motor, do flow control, or in the mechanical shaft to do torque protection Is very necessary.

Remove the old winding and remove the residue in the tank, shall not damage the core or deformation of the groove teeth, as far as possible adhere to the original tooth shape, so that the tank lubrication cleaning. If the core is damaged, there is a burr to file with a file or trim the oil to avoid in the embedded line, the corners of the corners of the insulation materials and enameled wire. If you do not pay attention to the way, so that damage to the core, will add iron loss, resulting in reduced gear reducer power.Line drawing and manufacturing competition to do accurate, not too large or too small. If the conditions permit, as far as possible to shorten the end of the scale, in order to reduce the end of the winding oscillation, damage and coil fault. From the experimental material, the loss of the end of the winding is 25% ~ 50% of the total loss of the stator windings. If the length of the winding end is reduced by 20%, the windings are reduced by 10% and the power is 1.5%.The diameter of the selected enameled wire should be equal to the diameter of the enameled wire of the original machine. The maximum outer diameter of the round copper enameled wire is 0.03 ~ 0.09mm larger than its nominal diameter. If the selection of large diameter, will affect the slot full rate, add the difficulty of embedded line. If you want to increase the wire diameter, to calculate the slot full rate, so that the groove full rate of about 80%.When winding the coil, the number of turns of the coil as much as possible with the original machine coil turns, the coil group head and tail should be marked. If the original motor no-load current is large, the number of turns per phase winding can be added as appropriate 5%, that is, the corresponding increase in the number of turns per coil 5%, no-load current is helical gear reducer by about 10%. If the original gear reducer is difficult to start, it is possible to reduce the number of turns per phase (the number of turns can not exceed 5%) and then add the starting torque. According to empty shell rewinding accounting, determine the number of turns per phase winding. View Details
