Problems solved by technology

However, in the actual manufacturing process, workers require relatively high alignment accuracy when aligning and fastening the fixed cover and the retainer body, which is difficult to operate and affects processing efficiency and fastening accuracy
In addition, workers will inevitably make mistakes when installing the wedges, and the wedges will be reversed, which will lead to problems such as one-way failure or even two-way jamming of the bearing rings (including the outer ring and inner ring). Seriously affect product quality

Abstract

The invention relates to a reverse stop bearing with a self-locating fastening bearing retainer, which includes an outer ring, an inner ring, a retainer body, steel balls, wedges and a fixed cover, and the fixed cover is arranged between the first end of the outer ring and the inner ring. Between the first end of the ring, the wedge spacing boss is provided with a fastening hole, and the bottom of the fixed cover is provided with a fastening card that matches the fastening hole. It is connected with the retainer body by buckling in place; it is characterized in that: a fan-shaped guide groove is provided on the wedge spacer boss, the fastening hole is located at the apex of the fan-shaped guide groove, and the arc edge of the fan-shaped guide groove is located On the top end surface of the wedge spacer boss, the depth of the fan-shaped guide groove gradually increases from its arc edge to its apex, and the bottom surface of the fan-shaped guide groove is an inclined plane. The present invention has simple structure and ingenious design, no very precise alignment is needed when the fixed cover is snapped and connected with the retainer body, and meanwhile, it has the ability to prevent reverse assembly of wedges and improves the processing efficiency.

Description

technical field [0001] The invention relates to a reverse stop bearing, in particular to a reverse stop bearing with a self-locating fastening bearing holder, which belongs to the technical field of mechanical transmission equipment. Background technique [0002] For today's bearing processing and manufacturing industry, there are many types of bearings, and some special-purpose bearings are also widely used. For example, a wedge type reverse stop bearing is particularly prominent in the washing machine industry, and this wedge type reverse stop bearing relies on its unidirectional running characteristics to realize the work of the washing machine. The existing wedge-type reverse stop bearings achieve the purpose of reverse stop through the cooperation of the wedge installed in the cage and the outer ring and inner ring. The existing cage is generally composed of a cage body and a matching The fixed cover is composed of a wedge notch on the retainer body, the wedge is first...
