Worm Gear is essential components in many mechanical systems, providing high torque transmission with a compact design. However, like all mechanical parts, Worm Gear is subject to wear and failure over time. Understanding the types of wear and failure mechanisms is crucial for improving the longevity and reliability of Worm Gear. This article delves into the common wear and failure modes of Worm Gear, their causes, and methods for prevention and analysis.
General introduction
Worm Gear is essential components in many mechanical systems, providing high torque transmission with a compact design. However, like all mechanical parts, Worm Gear is subject to wear and failure over time. Understanding the types of wear and failure mechanisms is crucial for improving the longevity and reliability of Worm Gear. This article delves into the common wear and failure modes of Worm Gear, their causes, and methods for prevention and analysis.

Main test mode
According to the specification Q/SQR S5-42-2019: First, secure the worm and worm gear on the test bench. Adjust the handle to the locked state, with the angle and height at the design position. Testing process: The system operates normally, and the input end drives the rotation speed at (250-300)°/s, pausing at both ends for 1-2 seconds; software collects test angle load in real-time, completing 50,000 cycles.
Fix the worm and worm gear on the test bench.
a) Rack load: 7.5kN (high load, converted to torque here, load provided by a magnetic powder clutch);
b) Rack stroke: over 90%; (converted to revolutions);
c) Load waveform diagram, the direction of the rack load and the direction of rack movement are opposite;
d) Input shaft speed: 30r/min;
e) Number of cycles: 1) high load, 100,000 cycles; 2) low load, 100,000 cycles (after high load).
Fix the worm gear and worm on the test bench and perform a total of 15,000 cycles from Step 1 to Step 7 according to the following methods:
a) Step 1: Angle ±80%, rack force 60%, rotation speed 320 deg/s, 2 times;
b) Step 2: Angle ±80%, rack force 80%, rotation speed 320 deg/s, 1 time;
c) Step 3: Angle ±95%, rack force 80%, rotation speed 360 deg/s, 1 time;
d) Step 4: Angle ±95%, rack force 90%, rotation speed 360 deg/s, 1 time;
e) Step 5: Angle ±100%, rack force 90%, rotation speed 360 deg/s, 2 times;
f) Step 6: Angle ±100%, rack force 80%, rotation speed 360 deg/s, 1 time;
g) Step 7: Angle ±100%, rack force 60%, rotation speed 360 deg/s, 1 time.
