Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as a basis for limiting the present invention.

[0017] Example.

[0018] The structure of the drawn outer ring needle roller bearing is as follows: figure 1 As shown, including - outer ring 11, needle roller 12 and rubber oil seal 13.

[0019] A method for assembling needle roller bearings with stamped outer rings: place the stamped outer rings, needle rollers and rubber oil seals in vibrating pans respectively, arrange the materials in an orderly orientation and drop them through the vibrating pans, and drop the stamped outer hoops one by one into the assembler Position, and press into the mold, then drop the needle roller into the stamped outer ring, then roll into the rubber oil seal, and finally press to complete the assembly of the bearing. The vibration frequency of the vibrating plate is controlled by the PC to control the falling speed ...

Abstract

The invention discloses a method and a device for assembling a drawn cup needle roller bearing. The method comprises the steps of placing drawn cups, needle rollers and rubber oil seals respectively into a vibrating tray, arranging and dropping materials orderly and directionally through the vibrating tray, gradually dropping the drawn cups into assembling stations one by one, then pressing a mould, dropping the needle rollers respectively into the drawn cups, rolling in the rubber oil seals, and finally punching to complete the assembling of the bearing. According to the method and the device, automatic assembling of the drawn cup needle roller bearing can be achieved, the assembling efficiency is high, and the assembling precision is high.

Description

technical field [0001] The invention relates to an assembly method and device for a needle roller bearing with a stamped outer ring, in particular to an automatic assembly method and device for a needle roller bearing with a stamped outer ring. Background technique [0002] Bearing ("Bearing", Japanese called "shaft receiver") is a component that fixes and reduces the load friction coefficient during mechanical transmission. It can also be said that when other parts move relative to each other on the shaft, it is used to reduce the friction coefficient in the process of power transmission and keep the center of the shaft fixed. Bearings are an important part of modern mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of the mechanical load during the transmission process of the equipment. [0003] Drawn cup needle roller bearings are commonly used bearings and are widely used in mechanical parts such as au...
