Description
Technical field
The utility model relates to technical field of bearings, is specifically related to a kind of unilateral bearing.
Background technique
Unilateral bearing is a kind of mechanical transmission basic part that only can the single direction transferring power, unidirectionally can freely rotate in one direction, and locked on another direction, mainly utilize bearing abnormity raceway and rolling element to cooperate the realization one-way function.Unilateral bearing is widely used in all kinds of occasions of the unidirectional transmission of needs, like package printing machinery, household electric appliance, fitness equipments etc., particularly automobile current generator transmission.Inertial force and moment of inertia were big when the automobile current generator belt pulley unilateral bearing of using at present rotated, and caused bearing wear fast, and it is bigger to produce noise, when high speed rotating, skids easily, functional inefficacy occurs, and working life is short.
Summary of the invention
The purpose of the utility model is: to the deficiency of existing technology, the utility model provides a kind of simple and reasonable, long service life, usability is good, precision is high unilateral bearing.
To achieve these goals, the technological scheme below the utility model has adopted:
A kind of unilateral bearing comprises the bearing outer ring and the bearing inner race of coaxial setting being provided with retainer between described bearing outer ring and bearing inner race; The outer side wall of described bearing inner race is provided with some grooves; Described retainer is provided with some maintenance seats, is embedded with roller between described maintenance seat, and described maintenance seat is provided with the screens boss near a side of bearing inner race; Described screens boss engages setting with groove; The described seat that keeps is provided with spring near a side of bearing outer ring, and a side of described spring is provided with the shell fragment that is equipped with roller, is provided with arc slope on the described bearing inner race outer side wall between adjacent grooves; When roller was pressed into the arc slope, described roller and shell fragment formed butt and are equipped with.
As preferably, a side on described arc slope is provided with guiding surface, and described guiding surface is positioned at the side of arc slope away from shell fragment.After adopting above-mentioned preferred version; At the bearing outer ring of unilateral bearing when the shell of outside rotates; Roller rolls on the bearing inner race outer side wall thereupon and is pressed into arc and breaks; The arc slope is provided with guiding surface, and roller is rolled in the arc slope along guiding surface reposefully, has improved the stability of unilateral bearing.
As preferably, described bearing outer ring is provided with two bearing outer ring ribs that are provided with at interval vertically, and described bearing outer ring rib radially extends inwardly.After adopting above-mentioned preferred version, the structure of bearing outer ring is more compact, can fix the parts in the bearing outer ring simultaneously, prevents displacement.
As preferably, described retainer is embedded between described bearing outer ring two ribs.After adopting above-mentioned preferred version; Described retainer is fixedly installed between the rib of bearing outer ring; The axial position of retainer is restricted; Thereby avoided displacement, improved the stability of unilateral bearing, prolonged the working life of unilateral bearing at unilateral bearing process middle (center) bearing retainer.
As preferably, described spring is provided with spring card slot, and described spring card slot engages setting with keeping seat.After adopting above-mentioned preferred version, spring is installed more firm with cooperating of retainer.
The unilateral bearing of the utility model realizes that the arc slope of one-way function is arranged on the outer surface of bearing inner race, at bearing outer ring when cooperating the shell rotation, particularly during high speed rotating; Bearing inner race and retainer are static relatively, and roller has only rotation under the bearing outer ring effect, so inertial force and moment of inertia obviously reduce; Be not prone to and skid; Rotate more steadily, the precision of bearing one-way function improves, and noise reduces; Because it is static relatively to have the bearing inner race and the retainer on unidirectional raceway arc slope, so make high speed performance improve, arc slope, roller 1 and retainer are not easy to wear when rotation or high speed rotating, thereby have improved bearing usability and bearing life.

Embodiment
Shown in Fig. 1～5, the utility model embodiment is a kind of unilateral bearing, comprises the bearing outer ring 1 and bearing inner race 2 of coaxial setting, and bearing outer ring 1 and bearing inner race 2 make through cold stamping.2 of bearing outer ring 1 and bearing inner races are provided with retainer 3, and retainer 3 is annotated by the engineering plastics mould and made.The outer side wall of bearing inner race 2 is provided with equally distributed groove 21, and the groove face of groove 21 is cambered surface, and the quantity of groove 21 can be processed according to actual conditions.Retainer 3 is provided with uniform maintenance seat 31; Keep the quantity of seat 31 identical with groove quantity; Keep 31 of seats to be embedded with roller 4; Keep seat 31 sides near bearing inner race 2 to be provided with screens boss 32, screens boss 32 engages setting with groove 21, and the surface of screens boss 32 is the convex globoidal suitable with groove 21.Keep seat 31 sides near bearing outer ring 1 to be provided with spring 5, a side of spring 5 is provided with the shell fragment 51 that is equipped with roller 4, and the surface configuration of shell fragment 51 and roller 4 are suitable.Spring 5 is provided with spring card slot 52, and spring card slot 52 engages setting with keeping seat 31.Be respectively equipped with an arc slope 22 on bearing inner race 2 outer side walls between the adjacent groove 21, arc slope 22 is the roller surface of roller 4.One side on arc slope 22 is provided with guiding surface 221, and guiding surface 221 is positioned at arc slope 22 sides away from shell fragment 51.When roller 4 was pressed into arc slope 22, roller 4 formed butts with shell fragment 51 and is equipped with.
Bearing outer ring 1 is provided with two bearing outer ring ribs 11 that are provided with at interval vertically, and bearing outer ring rib 11 radially extends inwardly.Retainer 3 is embedded between 1 liang of rib 11 of bearing outer ring.
As shown in Figure 1; During work, bearing outer ring 1 turns clockwise with the outside shell that cooperates, and roller 4 rotates at the outer side wall of bearing inner race 2 thereupon; Roller 4 moves along guiding surface 221 from shallow to deep, is pressed in the arc slope 22 at last and forms butt with the shell fragment 51 of spring 5 to cooperate.Shell fragment 51 is oppressed, and roller 4 is stabilized in the arc slope 22 and also forms engagement with it under the effect of pushing of shell fragment 51, has realized the transmission of power.When bearing outer ring 1 with outside when cooperating shell to be rotated counterclockwise; Roller 4 is thereupon toward motion counterclockwise, and to shallow motion, roller 4 breaks away from the butt with shell fragment 51 from 22 depths, arc slope; Shell fragment 51 release pressures of spring 5; Roller 4 withdraws from engagement, thereby bearing outer ring 1 is stopped operating, and realizes locking.
The bearing outer ring 1 of the utility model obtains through cold stamping with bearing inner race 2, and retainer 3 is annotated by the engineering plastics mould and formed, and spring 5 is the five metals general part; Roller 4 is the bearing general part; The unilateral bearing overall structure is simple, and is easy to manufacture, reduced difficulty of processing and cost of production.
