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 invention relates to a reverse stop bearing with a wedge reverse-mounting preventing bearing retainer. A retainer body is arranged between an inner ring and an outer ring; a steel ball is arranged in each ball pocket on the circumferential surface of the retainer body; a wedge is arranged in each wedge notch formed in the first end surface of the retainer body; a wedge spaced boss is arranged between the adjacent wedge notches; a fixed cover is connected with the first end of the retainer body. The reverse stop bearing is characterized in that a spring groove, of which one end is opened, is formed in each wedge spaced boss; the opening ends of the spring slots are communicated with the wedge notches in front of the inner ring of the bearing in the one-way rotation direction; compressed springs are arranged in the spring grooves; the inner ends of the compressed springs are connected with the retainer body; the outer ends of the compressed springs are exposed from the opening ends of the spring grooves and jack against the wedges, so that the wedges are still adhered to the outer ring and the inner ring. According to the reverse stop bearing, the normal operation of the wedges cannot be influenced, the capability of preventing reverse-mounting of the wedges is improved, the machining efficiency of the product is improved, the product quality is guaranteed, and the production cost is reduced.

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...
