Precision bearing life test equipment

Abstract

The invention relates to precision bearing life test equipment comprising a base plate. The precision bearing life test equipment is characterized in that a loading plate is arranged at one end of the base plate, a U-shaped slot frame is fixedly arranged on the lower surface of the loading plate, a speed reduction motor is arranged at the other end of the base plate, and an eccentric wheel is arranged on a power output shaft of the speed reduction motor; the eccentric wheel is connected with the loading plate by virtue of a connecting rod, and two ends of the connecting rod are respectively connected with the eccentric wheel and the loading plate by virtue of a knuckle bearing; a plurality of plastic coated wheels are arranged at the lower end of the loading plate, the plastic coated wheels are positioned on two sides of the U-shaped slot frame, the inner cavity of each plastic coated wheel is a cavity for mounting a to-be-tested bearing, and an end cover is arranged on the outer side of each plastic coated wheel; and a shaft with screw threads at two ends is arranged in an inner hole of the to-be-tested bearing, two ends of the shaft are erected on two sides of the U-shaped slot frame, shaft sleeves are respectively arranged at two ends of the shaft, nuts are screwed at the screw threads of the two ends of the shaft, and the shaft sleeves at the two ends of the shaft are tightly clamped with the inner ring end surface of the to-be-tested bearing under screwing and pressing of the nuts. The precision bearing life test equipment disclosed by the invention can be used for testing and detecting whether the performance of the bearing reaches standards according to the specific requirements of customers.

Description

technical field [0001] The invention relates to precision bearing life testing equipment, in particular to equipment for simulating heavy-load and low-speed verification of bearing life, and belongs to the technical field of detection and verification of bearing processing equipment. Background technique [0002] Whether the bearing performance (including service life, noise level of the bearing during use, grease loss and wear, etc.) can meet the requirements under the limit of the working conditions (limit speed, limit load, limit life, etc.); bearing design, process The quality inspection and factory inspection cannot verify whether the bearing can meet the limit requirements of customers (especially in the high-end fields of automobiles and aviation); customers require bearing manufacturers to provide bearing performance (life, noise, grease loss) of their bearings under extreme conditions , clearance variation, etc.) data, at this time, it is necessary to carry out a si...

AI Technical Summary

Problems solved by technology

Many bearing manufacturers cannot confirm whether their products can satisfy customers (especially high-end customers such as automobiles) and cannot enter high-end supporting industries

[0003] The vast majority of the domestic bearing industry pays attention to production, and does not pay enough attention to the verification of product performance. The verification method is simple and the equipment is lacking. It is difficult to improve the quality of products through test verification to ensure the improvement and stability of bearing quality. , resulting in frequent problems with the products for customers, and high-end customers dare not use bearings made in China
