A bearing roller size and circular runout detection device and using method

Abstract

A bearing roller size and circular runout detection device, including a base, a V-shaped block is fixedly installed on the top of the base, a roller is placed in the groove of the V-shaped block, and a first arc is attached to the outer side of the roller. The first arc-shaped plate is provided with a second arc-shaped plate away from the roller, and a connecting plate is fixedly installed between the second arc-shaped plate and the first arc-shaped plate. The first arc-shaped plate The cylinder body is fixedly installed on the upper array. The beneficial effects of the invention are: the structure detection of the invention is easy to operate, and the dimensional accuracy and circular runout error of the bearing rollers can be measured simultaneously, the measurement time is short, the measurement results are intuitive, and automatic measurement can be performed. For measurement, you only need to install the roller on the equipment to measure, without professional operation, which greatly improves the measurement efficiency, and the overall structure of the equipment is simple, not easy to damage, and the cost is low, which further improves the production efficiency.

Description

technical field [0001] The invention relates to the technical field of measuring equipment, in particular to a bearing roller size and circular runout detection device and a use method. Background technique [0002] At present, the rolling bearing is a precision mechanical element that changes the sliding friction between the running shaft and the shaft seat into rolling friction, thereby reducing friction loss. Rolling bearings are generally composed of four parts: inner ring, outer ring, roller and cage. The function of the inner ring is to cooperate with the shaft and rotate together with the shaft; the function of the outer ring is to cooperate with the bearing seat to play a supporting role; The cage evenly distributes the rollers between the inner ring and the outer ring. The roller is the core component of the rolling bearing. Due to its existence, there is rolling friction between the relative moving surfaces.

Problems solved by technology

Rolling bearings are generally composed of four parts: inner ring, outer ring, roller and cage. The function of the inner ring is to cooperate with the shaft and rotate together with the shaft; the function of the outer ring is to cooperate with the bearing seat to play a supporting role; The cage evenly distributes the rollers between the inner ring and the outer ring. The roller is the core component of the rolling bearing. Due to its existence, there is rolling friction between the relative moving surfaces. The roller is the part that bears the load when the bearing is running. The component is the weakest part in the roller bearing. Its manufacturing quality has a great influence on the working performance of the bearing (such as rotation accuracy, vibration, noise and flexibility, etc.), and is the main factor affecting the service life of the bearing. The roller The dimensional accuracy of the bearing determines the quality and durability of the bearing to a large extent, so the dimensional accuracy and circular runout error of the roller need to be controlled very precisely, but the existing rolling bearing has a low yield rate and poor durability. The reason is that , the measurement of the size of the roller is very inconvenient and needs to be measured by professional measuring equipment, but the professional equipment is expensive, the operation is cumbersome, there are many measurement items, the measurement is time-consuming, and the operation requires professionals to operate, so it is not suitable for ordinary production. processing
