Abstract
The utility model provides a universal mechanical part, particularly a low-resistance ball bearing. The low-resistance ball bearing has the structure that the low-resistance ball bearing is composed of an outer bearing sleeve, an intermediate bearing sleeve, an inner bearing sleeve and steel balls, wherein the outer bearing sleeve, the intermediate bearing sleeve and the inner bearing sleeve are layered and arranged from exterior to interior; the steel balls are layered and connected with square grooves arranged in the outer bearing sleeve, the intermediate bearing sleeve and the inner bearing sleeve. The low-resistance ball bearing of the utility model has the characteristics of reasonable design, less friction resistance, etc.; the work efficiency and the service life of a mechanical device can be improved when the utility model is widely used for the mechanical device, and the utility model can reduce the energy consumption when used for an electric tool of a traffic vehicle.
Description
1, technical field
The utility model relates to a kind of universal machine component, specifically lower resistance ball bearing.
2, technical background
Bearing is the universal machine component that people know, and is widely used between the transmission and rotatable parts of machinery, in order to alleviate the surface friction drag between parts and the parts, increases work efficiency, the consumption of working life and the minimizing energy.But its structure of each class bearing of prior art be mostly to be provided with between the interior outer bearing sleeve one the circle rolling steel ball, interior outer bearing sleeve respectively with two in relative rotation object fix.The in use existing deficiency of the rolling bearing of prior art be can not with two in relative rotation the resistance of object reduce to minimum, can not make the operational efficiency of machinery or reach the optimum state working life.
3, summary of the invention
It is little that the purpose of this utility model provides a kind of surface friction drag, the working efficiency of machinery can be brought up to the lower resistance ball bearing of maximum low surface friction drag.
The purpose of this utility model realizes in the following manner, the design bearing that the individual layer steel ball is set in the middle of the exterior and interior axle sleeves with prior art becomes between the interior outer cylinder sheath multilayer bearing bush is set, steel ball all is set between the axle sleeve, the groove that axle sleeve contacts with steel ball changes square new-type lower resistance steel ball rolling bearing into by arc
Accompanying drawing is the structural representation of lower resistance ball bearing.
4, description of drawings
With reference to accompanying drawing lower resistance ball journal of the present utility model is made following explaining.
A kind of sheave block bearing of the present utility model, as shown in drawings, its structure is to be made of outer bearing sleeve 1, intermediate bearing sleeve 2, internal bearing sleeve 4 and steel ball 3, outer bearing sleeve 1, intermediate bearing sleeve 2, internal bearing sleeve 4 ecto-entad layerings are provided with, and steel ball 3 layerings are joined with the square groove of opening on outer bearing sleeve 1, intermediate bearing sleeve 2 and internal bearing sleeve 45.
5, mode of execution
Lower resistance ball bearing of the present utility model, its processing and fabricating is very simple and convenient, and by specification structure shown in the drawings is pressed the making of traditional bearing preparation process and is got final product.
Lower resistance ball bearing of the present utility model is compared with prior art, have reasonable in design, frictional resistance is little, each bearing housing is inlayed the square groove corner part of steel ball can store a large amount of lubricant oil, effectively prolong the lubrication time of lubricant oil, thereby, in machinery, be extensive use of working efficiency and the working life that can improve machinery, on the vehicular traffic electric tool, use characteristics such as capable of reducing energy consumption, thereby, have good value for applications.
Except that the described technical characteristics of specification, be the known technology of those skilled in the art.
Claims (1)
1. lower resistance ball bearing, comprise outer bearing sleeve, intermediate bearing sleeve, internal bearing sleeve and steel ball, it is characterized in that outer bearing sleeve, intermediate bearing sleeve, internal bearing sleeve ecto-entad layering setting, the steel ball layering is joined with the square groove of opening on outer bearing sleeve, intermediate bearing sleeve and internal bearing sleeve.
