Problems solved by technology

[0002] The torque limiter is an important component of a certain type of steering gear, and its structure is shown in figure 1 Among them, the 130-tooth gear is imported from France. The original state is composed of friction materials on both sides of the metal gear. Later, the supplier changed the technical status of the part and provided an integrated part of powder metallurgy and basic materials. Due to the 130-tooth gear Changing the technical status, the slipping torque of the torque limiter component was found to be unstable during assembly, and there was a jumping phenomenon, which in turn caused the final steering gear to work for a period of time and the slipping current was unstable, which made the assembly and debugging work unable to proceed normally, with low pass rate and poor reliability. , severely impacting production deliveries

Embodiment Construction

[0015] Attached below figure 1 , 2 The present invention is described in further detail.

[0016] A method for improving the slip torque of a friction torque limiter, characterized in that it comprises the following steps:

[0017] (1) Grinding both ends of 130-tooth gear parts;

[0018] (2) Engraving net pattern on both ends of 130-tooth gear parts;

[0019] (3) Pre-assembled in the torque limiter; first use a brush to clean the surface of the friction plate to remove excess oxides on the surface, apply grease on the 130-tooth gear and assemble it with other parts to form an assembly, and manually rotate it about 5 times left and right , Disassemble the components for cleaning, and use a brush to scrub the surface of the 130-tooth gear. The texture on the surface of the 130-tooth gear should be clearly visible, and then reassemble the components for torque adjustment.

[0020] The grinding of the two ends of the 130-tooth gear part requires that the perpendicularity relat...

Abstract

The invention belongs to the field of electromechanical equipment, and relates to a method for improving sliding moment of a friction moment limiter. The method is characterized in that the two end surfaces of a gear are grinded, so that contact surfaces are guaranteed; reticulate patterns are carved to increase friction force of the gear, and sliding moment of the moment limiter is improved; andpre-assembly is performed in the moment limiter, so that sliding moment of a product is guaranteed to be stable and reliable, a qualification rate is high, and range of application is wide.
