Abstract
Bearing with annular knurl in a kind of bearing outside diameter intermediate channel disclosed in the utility model, comprise bearing outer ring and bearing inner race, retainer is provided with between described bearing outer ring and bearing inner race, ball is provided with in the ball pocket of described retainer, the middle part of described bearing outer ring outer ring surface is provided with an annular groove cooperatively interacted with bearing support, is provided with annular knurl in described annular groove.The beneficial effects of the utility model are: the annular groove coordinated with bearing support set by the middle part of the outer ring surface of bearing outer ring, make bearing be fixed in bearing support, it are played to the effect of location.Annular knurl set in annular groove efficiently solves plastic bearing seat makes the gap of bearing saddle bore and bearing outer ring increase owing to expanding after being heated, cause bearing operation not steady, the problem that noise is large, nor the performance that can affect bearing because of long caused bearing wear generation relative angle change service time.
Description
Technical field
The utility model relates to a kind of bearing, particularly relates to the bearing with annular knurl in a kind of bearing outside diameter intermediate channel.
Background technique
Bearing (" Bearing ", Japan's person " axle is subject to ") is in mechanical transmission course, play parts that are fixing and reduction load friction factor.Alternatively, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor in power transmission process and retainer shaft central position.Bearing is a kind of very important component in contemporary machinery.Its major function is supported mechanical solid of rotation, in order to reduce the mechanical load friction factor of equipment in transmission process.
Existing bearing is directly installed on bearing support, especially bearing block bearing seat is made of plastics, rise owing to having temperature after bearing operation, easily expand after plastics are heated, the gap of bearing saddle bore and bearing outside diameter is increased, causes bearing operation not steady, produce larger noise, and in long operation process, bearing there will be wearing and tearing, to such an extent as to there is the change of relative angle in bearing in bearing support.
Model utility content
Technical problem to be solved in the utility model: the bearing with annular knurl in a kind of bearing outside diameter intermediate channel is provided for the deficiencies in the prior art.
The technical problem that the utility model solves can realize by the following technical solutions:
Bearing with annular knurl in a kind of bearing outside diameter intermediate channel, comprise bearing outer ring and bearing inner race, retainer is provided with between described bearing outer ring and bearing inner race, ball is provided with in the ball pocket of described retainer, the middle part of described bearing outer ring outer ring surface is provided with an annular groove cooperatively interacted with bearing support, is provided with annular knurl in described annular groove.
In a preferred embodiment of the present utility model, on the inner ring surface of described bearing outer ring and on the outer ring surface of described bearing inner race, be provided with the annular arc connected in star for the spacing activity of described ball.
Owing to have employed technological scheme as above, the beneficial effects of the utility model are: the annular groove coordinated with bearing support set by the middle part of the outer ring surface of bearing outer ring, make bearing be fixed in bearing support, it are played to the effect of location.Annular knurl set in annular groove efficiently solves plastic bearing seat makes the gap of bearing saddle bore and bearing outer ring increase owing to expanding after being heated, cause bearing operation not steady, the problem that noise is large, nor the performance that can affect bearing because of long caused bearing wear generation relative angle change service time; Annular arc connected in star on the inner ring surface of bearing outer ring and on the outer ring surface of bearing inner race enhances stability during ball work in bearing.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See Fig. 1, bearing with annular knurl in a kind of bearing outside diameter intermediate channel provided in figure, this bearing is arranged in bearing support, it comprises bearing outer ring 100, bearing inner race 200, retainer 300 and ball 400, retainer 300 is arranged between bearing outer ring 100 and bearing inner race 200, retainer 300 is evenly distributed with some ball pockets 310, ball 400 is arranged in ball pocket 310, so effectively makes the load of bearing even.
The middle part of the outer ring surface of bearing outer ring 100 is provided with an annular groove 110, and annular groove 110 coordinates with bearing support, to make bearing be fixed in bearing support, it is played to the effect of location.Annular knurl 111 is provided with in annular groove 110, the design of annular knurl 111 solves plastic bearing seat very well makes the gap of bearing saddle bore and bearing outer ring 100 increase owing to expanding after being heated, cause bearing operation not steady, the problem that noise is large, nor the performance that can affect bearing because of long caused bearing wear generation relative angle change service time.
In order to strengthen stability when ball 400 works in bearing, on the inner ring surface of bearing outer ring 100 and on the outer ring surface of bearing inner race 200, be provided with the annular arc connected in star 120,210 for the spacing activity of ball 400.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
