Speed Reducer Selection Guide

The selection of reducer should be examined for its structure type, installation form, load-bearing capacity, output speed, working conditions and other factors. Determination of reducer sample specifications: The load-bearing capacity of the reducer is derived under the conditions of rated speed, working less than 12 hours per day, starting less than 10 times per hour, and flat without impact. If there are different use cases should be selected according to the following steps.

（一）Check the selected configuration

The use factor f is determined by the type of load, the number of starts and stops per hour and the expected working life

Usage factor (fs)
Load Type	Number of starts per hour Z	Daily running time (h)
Load Type	Number of starts per hour Z	h<4	4<h<8	8<h<12	12<h<16	16<h<24
Uniform load	Z<10	0.85	0.95	1.00	1.20	1.60
	10<Z<30	0.90	1.10	1.15	1.40	1.80
	30<Z<100	1.00	1.20	1.30	1.60	2.00
Medium load	Z<10	1.00	1.20	1.30	1.60	2.00
	10<Z<30	1.10	1.35	1.45	1.80	2.20
	30<Z<100	1.20	1.45	1.60	2.00	2.40
Heavy load	Z<10	1.20	1.45	1.60	2.00	2.40
	10<Z<30	1.30	1.55	1.75	2.20	2.60
	30<Z<100	1.40	1.65	1.90	2.40	2.80

The safety factor can be selected according to the following table

Usage requirements	Minimum safety factor
High reliability	1.50~1.60
High reliability	1.25~1.30
General Reliability	1.00~1.10

1. Maximum torque

Confirm that the instantaneous peak load torque and starting torque with load cannot exceed the rated maximum torque T of the reducer. The specific parameter values are listed in the reducer rating table.
2.Cantilever load

Mainly for cantilevered rack and pinion, timing belt pulley, etc. need to carry large radial force or axial force. Selection of swing, in accordance with a certain speed and the force point in the shaft extension a 1/2 consider, require Cao inter need radial force or axial force is less than the standard value of the sample (pay attention to the speed of rotation value. The lower the rotational speed, the relative bearing radial force will improve the force paste farther away from the shoulder of the shaft, the bearing radial force will decline).
