Problems solved by technology

However, in the actual manufacturing process, workers will inevitably make mistakes when installing the wedges, and the wedges will be reversed, which will lead to unidirectional failure or even failure of the bearing rings (including outer and inner rings). Problems such as two-way jamming seriously affect product quality

Abstract

The present invention relates to reverse stop bearings with anti-wedge reverse mount bearing retainers. The retainer body is arranged between the outer ring and the inner ring, a steel ball is installed in each ball pocket on the circumferential surface of the retainer body, and a wedge is installed in each wedge notch on the first end face of the retainer body, correspondingly Between the notches of adjacent wedges is a wedge spacer boss; the fixed cover is connected to the first end of the retainer body; it is characterized in that: each of the wedge spacer bosses is provided with a spring slot with an open end, so The opening end of the spring groove communicates with the wedge notch in front of the inner ring of the bearing in the direction of one-way rotation. The spring groove is equipped with a compression spring. The inner end of the compression spring is connected to the retainer body. The outer end of the compression spring is exposed from the opening end of the spring groove and pushed Hold the wedges so that they remain snug against the outer and inner rings at all times. The invention does not affect the normal operation of the wedge and has the ability to prevent the reverse assembly of the wedge, improves the processing efficiency of the product, ensures the quality of the product, and reduces the production cost.

Description

technical field [0001] The invention relates to a reverse stop bearing, in particular to a reverse stop bearing with an anti-wedge anti-installation bearing retainer, 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 bearing achieves the purpose of reverse stop through the cooperation of the wedge and the outer ring and the inner ring, which has strict requirements on the installation direction of the wedge. However, in the actual manufacturing process, workers will inevitably make mistakes when in...
