Abstract
The utility model provides a bearing mounted on a hand buggy. The bearing comprises an outer ring, an inner ring, steel balls, retainers and dustproof covers, wherein the steel balls and the retainers are mounted between the outer ring and the inner ring in a fitting manner; the dustproof covers are fixedly clamped on two sides of the outer ring and the inner ring; a groove is formed in the outer wall of the outer ring; a clamping device is arranged in the groove and comprises a spring, a mandril and a round ball; the lower end of the spring and the outer ring are fixed through welding; the upper end of the spring and the mandril are fixed through welding; the round ball is arranged at the top end of the mandril; the mandril can move up and down along the groove; the round ball props against the inner wall of a bearing pedestal. The bearing is simple in structure; under the action of the spring, the round ball of the bearing is in contact with the inner wall of the bearing pedestal, so that the bearing is stably mounted in the bearing pedestal and has small possibility of falling off.
Description
Technical field
The utility model relates to driving component technical field, relates in particular to a kind of bearing being arranged on hand buggy.
Background technique
Bearing is in mechanical transmission course, to work the parts of fixing and reducing load friction factor.Also can say, in the time that other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor and retainer shaft central position in power transmission process.Bearing is a kind of very important component in contemporary machinery.Its major function is supported mechanical solid of rotation, the mechanical load friction factor in order to reduction equipment in transmission process.Press the difference of motor element frictional property, bearing can be divided into rolling bearing and sliding bearing two classes.Bearing is installed on hand buggy, and service time one is long, and bearing and bearing support can produce gap, and bearing easily comes off in bearing support, installs firm not.
Model utility content
(1) technical problem that will solve
Problem to be solved in the utility model is to provide a kind of bearing being arranged on hand buggy, easily in bearing support, comes off to overcome prior art middle (center) bearing, and firm not defect is installed.
(2) technological scheme
For solveing the technical problem, the utility model provides a kind of bearing being arranged on hand buggy, comprises outer ring, inner ring, steel ball, retainer and dust cover; Described steel ball coordinates with described retainer and is arranged between described outer ring and described inner ring; Described dust cover is fixed on the both sides of described outer ring and described inner ring; The outer wall top of described outer ring has groove, in described groove, be provided with gripping mechanism, described gripping mechanism comprises spring, push rod and ball, described spring lower end and described outer ring are welded and fixed, described spring upper end and described push rod are welded and fixed, described ball is arranged on the top of described push rod, and described push rod can move up and down along described groove, and described ball pushes up mutually with the inwall of bearing support.
Further, described outer ring also has the first oil inlet hole.
Further, described inner ring one side is provided with the second oil inlet hole, and described second oil inlet hole one end is communicated with described bearing is outside, and the other end is communicated with the inwall of described inner ring.
Further, described retainer is made up of nylon material.
Further, described steel ball size is 3.969mm, and described inner ring length is 14.9mm.(3) beneficial effect
The bearing being arranged on hand buggy of the present utility model, simple in structure, under the effect of spring, the ball of bearing contacts with the inwall of bearing support, bearing is arranged in bearing support more firm, difficult drop-off.
Brief description of the drawings
Fig. 1 is a kind of structural representation that is arranged on the bearing on hand buggy of the utility model;
Fig. 2 is the partial enlarged drawing of A in Fig. 1;
Fig. 3 is the structural representation of a kind of bearing being arranged on hand buggy of the utility model while coordinating with bearing support.
In figure, 1 is outer ring, and 2 is inner ring, and 3 is steel ball, and 4 is retainer, and 5 is dust cover, and 6 is spring, and 7 is push rod, and 8 is ball, and 9 is groove, and 10 is the first oil inlet hole, and 11 is the second oil inlet hole, and 12 is bearing support.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As depicted in figs. 1 and 2, a kind of bearing being arranged on hand buggy of the present utility model, comprises outer ring 1, inner ring 2, steel ball 3, retainer 4 and dust cover 5; Described steel ball 3 coordinates and is arranged between described outer ring 1 and described inner ring 2 with described retainer 4; Described dust cover 5 is fixed on the both sides of described outer ring 1 and described inner ring 2; The outer wall top of described outer ring 1 has groove 9, in described groove 9, be provided with gripping mechanism, described gripping mechanism comprises spring 6, push rod 7 and ball 8, described spring 6 lower ends and described outer ring 1 are welded and fixed, described spring 6 upper ends and described push rod 7 are welded and fixed, described ball 8 is arranged on the top of described push rod 7, and described push rod 7 can move up and down along described groove 9, and described ball 8 pushes up mutually with the inwall of bearing support 12.
As shown in Figure 1, described outer ring 1 also has the first oil inlet hole 10.
As shown in Figure 1, described inner ring 2 one sides are provided with the second oil inlet hole 11, and described second oil inlet hole 11 one end are communicated with described bearing is outside, and the other end is communicated with the inwall of described inner ring 2.
When installation, as shown in Figure 3, bearing is installed on the bearing support 12 on hand buggy, under the effect of spring 6, ball 8 contacts with the inwall of bearing support 12, bearing is arranged in bearing support 12 more firm, is difficult for mobile.Gripping mechanism plays the effect of filling up gap.
The bearing being arranged on hand buggy of the present utility model, simple in structure, under the effect of spring, the ball of bearing contacts with the inwall of bearing support, bearing is arranged in bearing support more firm, difficult drop-off.
In sum, above-mentioned mode of execution is not restricted mode of execution of the present utility model, and the modification that all those skilled in the art carry out on the basis of flesh and blood of the present utility model or equivalent deformation, all at technology category of the present utility model.
