The selection of gear precision of planetary reducer generally considers economic factors. The precision of precision gears has a relatively large impact on noise and backlash. Generally speaking, the noise generated by high-precision gears will be smaller, otherwise the noise will be very loud.
The gear width is also a factor that affects the noise of the gear. Increasing the gear width will reduce the load, and at the same time, the bearing capacity of the gear will also increase. When the torque is constant, the small gear will be noisier than the large gear. The pinion can be in contact with multiple gears at the same time, reducing the noise of gear transmission and improving the precision of gear transmission. If the pressure angle is relatively small, the noise of the gear during operation can be reduced, and the precision of the gear can also be improved.
When designing and manufacturing precision gears, attention should be paid to the errors of gear accuracy, including tooth pitch and tooth direction errors. In order to ensure the accuracy of the gears, these errors must be eliminated, so as to improve the efficiency of the planetary reducer. When the gear assembly is not concentric, it will cause the shaft system to run unbalanced. If the high-precision gear is unbalanced, it will have a negative impact on the precision of the planetary reducer. The low hardness of the tooth surface will make the gear operation of the planetary reducer fail.
The above is the impact of precision gears on planetary reducers
