Description
Technical field
The utility model relates to a kind of bearing, particularly relates to a kind of ball bearing.
Background technique
Bearing rises fixing in mechanical transmission course and reduces the parts of load friction factor, alternatively, when other parts produce relative movement each other on axle, is 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, and its major function is supported mechanical solid of rotation, in order to reduce the mechanical load friction factor of equipment in transmission process.By the difference of motor element frictional property, bearing can be divided into rolling bearing and sliding bearing two class.
Rolling bearing is that the force of sliding friction between the axle of running and axle bed is become force of rolling friction, thus reduce the mechanical component of a kind of precision of frictional loss, rolling bearing generally by outer race, bearing inner ring, retainer and rolling element four part form, the effect of bearing inner ring is that the merging that matches with axle rotates together with the axis; Outer ring effect matches with bearing support, plays a supportive role; Rolling element is distributed between bearing inner ring and outer race by rolling element uniformly by means of retainer, and its shape size and quantity directly affect usability and the life-span of rolling bearing; Retainer can make rolling element be uniformly distributed, and prevents rolling element from coming off, and guides rolling element to rotate lubricate; When rolling element is ball, rolling bearing is also known as ball bearing.Current ball bearing does not have dustproof construction mostly, and the service time of bearing has been grown, and easily causes ball wear and tear and get rusty, shortens the working life of bearing.
Model utility content
For solving the problems of the technologies described above, the purpose of this utility model is to provide one and can prevents dust from entering Bearing inner, and ball not easily gets rusty and weares and teares, the ball bearing of long service life.
Ball bearing of the present utility model, comprises outer race, bearing inner ring, retainer and ball, described bearing inner ring is symmetrically arranged with the dust board of two ring-types, and described dust board is positioned at the both sides of described retainer; Described bearing inner ring is provided with multiple first draw-in groove and multiple second draw-in groove that two circles arrange in the form of a ring, the inside bottom surface of described dust board is provided with multiple first fixture block and multiple second fixture block that two circles arrange in the form of a ring, the bottom interior wall of described first draw-in groove and the second draw-in groove is provided with the positioning groove of ring-type, the top outer rim of described first fixture block and the second fixture block is provided with the positioning strip of ring-type, described first fixture block and the second fixture block are installed in described first draw-in groove and the second draw-in groove respectively, and described positioning strip and positioning groove clamp mutually; The outer side covers of described dust board is in the outside of described outer race, described outer race is provided with the clamp of ring-type, described clamp is provided with the multiple first auxiliary ball of arranging in the form of a ring, the exterior bottom and described first of described dust board assists that ball is relative to roll.
Further, the outside of described outer race is also provided with position-limit mechanism, described position-limit mechanism comprises the limiting board of L-type and is arranged on the auxiliary ball of second on limiting board, the side of described limiting board is fixed on described outer race by fixed block, the opposite side bottom surface of described limiting board arranges the described second auxiliary ball, the end face of described dust board and bottom surface ball auxiliary with described first and second auxiliary ball is relative rolls respectively.
Concrete, described fixed block is retaining screw.
Further, described first fixture block is quality of rubber materials first fixture block.
Further, described second fixture block is quality of rubber materials second fixture block.
Further, described dust board is provided with oil hole.
By such scheme, the utility model at least has the following advantages: can prevent dust from entering Bearing inner, ball not easily gets rusty and weares and teares, long service life.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model ball bearing;
Fig. 2 is the partial enlarged drawing in A portion in Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
See Fig. 1 and Fig. 2, a kind of ball bearing of the utility model one preferred embodiment, comprises outer race 1, bearing inner ring 2, retainer 3 and ball 4, and bearing inner ring 2 is symmetrically arranged with the dust board 5 of two ring-types, dust board 5 is positioned at the both sides of retainer 3; Bearing inner ring 2 is provided with multiple first draw-in groove 6 and multiple second draw-in groove 7 that two circles arrange in the form of a ring, the inside bottom surface of dust board 5 is provided with multiple first fixture block 8 and multiple second fixture block 9 that two circles arrange in the form of a ring, the bottom interior wall of the first draw-in groove 6 and the second draw-in groove 7 is provided with the positioning groove of ring-type, the top outer rim of the first fixture block and the second fixture block is provided with the positioning strip of ring-type, first fixture block 8 and the second fixture block 9 are installed in the first draw-in groove 6 and the second draw-in groove 7 respectively, and positioning strip and positioning groove clamp mutually; The outer side covers of dust board 5 is in the outside of outer race 1, outer race 2 is provided with the clamp 10 of ring-type, clamp 10 is provided with the multiple first auxiliary ball 11 of arranging in the form of a ring, the exterior bottom of dust board 5 and first auxiliary ball 11 is relative rolls, clamp is fixed on outer race by the fixed blocks such as screw 15.Like this, by dust board by the gap cover between outer race 1 and bearing inner ring 2, the excessive friction between dust board and outer race is prevented by the first auxiliary ball, so both can not affect the normal function of bearing, can prevent dust from entering Bearing inner simultaneously, ball not easily gets rusty and weares and teares, long service life.
