Embodiment Construction

[0015] The present invention will be further described below in conjunction with specific drawings.

[0016] Such as figure 1 As shown, the present invention relates to a cylindrical air-conditioning cabinet machine moving part bearing, including an outer ring 1, an inner ring 2, rolling elements 3, a cage 4 and a dust cover 5; the cage 4 is evenly provided with rolling elements 3; The dust cover 5 is pressed into the dustproof grooves at both ends of the outer ring 1; the present invention also includes a mandrel 6, the width of the inner ring 2 is greater than the width of the outer ring 1, improving the positioning accuracy of the product; The inner ring 2 is press-fitted into the core shaft 6 to form a whole body, and the inner ring 2 is tightly connected with the core shaft 6, and the core shaft 6 is a stepped shaft. Pressing the mandrel 6 reduces the customer's assembly error, avoids assembly instability, and improves the overall accuracy of the product.

Abstract

The invention relates to a cylindrical bearing of a moving part of a cabinet air conditioner. The bearing comprises an outer ring, an inner ring, rolling bodies, a retainer and dust covers, wherein the rolling bodies are uniformly arranged in the retainer; the dust covers are respectively pressed in dust grooves at the two ends of the outer ring; the bearing also comprises a mandrel; the width ofthe inner ring is larger than that of the outer ring; the mandrel is pressed into the middle of the inner ring to form a whole; the inner ring is in tight fit connection with the mandrel; and the mandrel is a stepped shaft. According to the bearing, the inner ring is wider than the outer ring, so that the positioning precision of products is improved; and the mandrel is pressed in the inner ring,so that assembly errors of customers are reduced, assembly instability is avoided, and overall accuracy of the products is improved.

Description

Technical field [0001] The invention relates to a cylindrical air-conditioning cabinet moving part bearing, which belongs to the technical field of air-conditioning accessories. Background technique [0002] At present, the bearings used for the moving parts of the cylindrical air-conditioning cabinet are mainly composed of outer ring, inner ring, cage, rolling element, dust cover, grease and so on. The rolling elements are installed between the outer ring and the inner ring, and the cage is used for positioning. The cage evenly separates the rolling elements and keeps the rolling elements moving correctly. Two pieces of metal dust caps are placed in the dust grooves of the outer ring. To prevent dust and grease from leaking, the grease plays a role of lubrication. This kind of bearing requires high positioning accuracy when it is assembled on working parts, and the surrounding environment of the bearing is prone to rust and failure due to high moisture.
