Stable and reliable bearing polishing machine

Abstract

The invention discloses a stable and reliable bearing polishing machine, which includes a frame and a support plate, on which a motor and a column are installed respectively, the output end of the motor runs through the lower section of the column and then extends horizontally outward, and the rotating shaft moves through the upper section of the column and Parallel to the output end of the motor, there is a driving gear and a limit block on the output end of the motor, and a plurality of washers are set between the limit block and the screw nut, and the bearings are arranged alternately between the two washers. The outer diameter of the washer It is larger than the inner diameter of the outer ring of the bearing, and the outer diameter of the washer is smaller than that of the outer ring of the bearing. At one end of the rotating shaft, there is a driven gear that cooperates with the driving gear, and at the other end of the rotating shaft, there is a brush. The outer circumferential wall of the brush and the washer touch. Multiple bearings are polished synchronously by brushes. When the number of revolutions of the output end of the motor is fixed, the grinding progress of multiple bearings is consistent, and the force on each part of the outer peripheral wall of a single bearing is balanced, thereby avoiding the external bearing of the bearing. Partial grinding of the circumferential wall is excessive and the bearing is scrapped.

Description

technical field [0001] The invention relates to a grinding tool, in particular to a stable and reliable bearing polishing machine. Background technique [0002] The main function of the hub bearing is to bear weight and provide precise guidance for the rotation of the hub. It bears both axial load and radial load, and is a very important component. Traditional automobile wheel bearings are composed of two sets of tapered roller bearings or ball bearings. The installation, oiling, sealing and clearance adjustment of the bearings are all carried out on the automobile production line. This structure makes it difficult to assemble in the automobile production plant, high in cost, and poor in reliability. Moreover, when the automobile is maintained at the maintenance point, the bearing needs to be cleaned, oiled and adjusted. When the bearing is exposed to the outside, its outer circumference is prone to rust, which will further lead to corrosion or damage of the bearing. In the...

Problems solved by technology

This structure makes it difficult to assemble in the automobile production plant, high cost, and poor reliability, and when the automobile is maintained at the repair point, the bearing needs to be cleaned, oiled and adjusted

When the bearing is exposed to the outside, its outer circumference is prone to rust, which will further lead to corrosion or damage of the bearing. In the prior art, the outer diameter is generally wiped with sandpaper one by one by manpower to remove rust, which is labor-intensive and time-consuming. And the appearance of the wiped place is prone to defects, and the probability of product scrapping is relatively high as a result.
