Abstract
The invention discloses a limiting bearing structure of a motorcycle engine. The limiting bearing structure comprises a bearing body, wherein an annular part and a locating part are arranged on an outer ring of the bearing body, wherein the annular part is used for preventing axial play of the bearing body; and the locating part is used for being matched with a pin hole formed in a crankshaft box body. According to the limiting bearing structure disclosed by the invention, the problem of vibration of the motorcycle engine adopting a vertical box closing structure due to rotation of a bearing outer ring and left-right play can be solved, and the service performance of the engine is improved; and in addition, the limiting bearing structure has the advantages of simple structure, convenience in processing and manufacturing and low cost.
Description
Technical field
The present invention relates to engine mounting parts field, more particularly to a kind of motorcycle engine Limit Bearing construction.
Background technology
Due to traditional left and right mould assembling structure, bearing is assemblied in the dead eye of casing, and dead eye is a complete circle,
The rotation of bearing top circle is limited by the interference fit of hole and bearing top circle；After axial aspect, right case mould assembling, pass through
Thrust and wall box position-limiting action, can limit bearing axial motion.But for the motorcycle using upper and lower mould assembling structure is sent out
Motivation, using existing bearing, then can cause engine vibration because of bearing outer ring rotation and left and right vibration, affect engine just
Often use.
The content of the invention
In view of this, it is an object of the invention to provide a kind of motorcycle engine Limit Bearing construction, can not only solve
Rotated and left and right vibration and caused engine vibration are asked because of bearing outer ring using the motorcycle engine of upper and lower mould assembling structure
Topic, lifts engine performance, and simple structure, is easy to processing and manufacturing, low cost.
The motorcycle engine Limit Bearing construction of the present invention, including bearing body, set on the outer ring of the bearing body
It is equipped with for preventing bearing body from producing the annular element of axial motion and the column pin hole for being provided with crankcase coordinates
Keeper.
Further, the bearing body outer ring is provided with the annular groove for installing annular element, and the annular element is set in ring
In groove.
Further, the keeper and annular groove are located at respectively bearing body axial direction both sides.
Further, the annular element is location collar.
Further, the width of the annular groove is 1～2mm, and the distance of annular groove distance between bearing body axial end is 2～4mm.
Further, the keeper is cylindrical-shaped structure.
Further, the bearing body is needle bearing, the needle bearing also include being arranged at retainer in outer ring and
Needle roller, the needle roller is supported between outer ring and retainer.
The invention has the beneficial effects as follows：The motorcycle engine Limit Bearing construction of the present invention, by arranging annular element, no
Only ensure that the stressed member uniform force on inside contact surface, the axle for preventing bearing from producing because of stress in operation process
To vibration, and sealing property can be improved, prevent contact surface machine oil from leaking outside；By arranging keeper so as to can be with bent axle
Column pin hole on casing is engaged, to limit the rotation that bearing outer ring is produced in circumferencial direction, so that the present invention can not only
Solve using the motorcycle engine of upper and lower mould assembling structure because bearing outer ring is rotated and left and right vibration and caused engine vibration
Problem, lift engine performance, and simple structure is easy to processing and manufacturing, low cost.
Description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the axonometric drawing of the present invention.
Specific embodiment
As shown in Figure 1 to Figure 2：The motorcycle engine Limit Bearing construction of the present embodiment, including bearing body 1, it is described
Be provided with the outer ring 2 of bearing body 1 for prevent bearing body 1 produce axial motion annular element 3 and for crankcase
The column pin hole that body is provided with coordinates keeper 4, by arranging annular element, can not only ensure the stressed member on inside contact surface
Uniform force, the axial motion for preventing bearing from producing because of stress in operation process, and sealing property can be improved, prevent
Contact surface machine oil leaks outside；By arranging keeper so as to can be engaged with the column pin hole on crankcase, to limit outside bearing
Enclose the rotation produced in circumferencial direction, so as to can not only solve the motorcycle engine using upper and lower mould assembling structure because of bearing outside
The problem of rotation and left and right vibration and caused engine vibration is enclosed, engine performance, and simple structure is lifted, is easy to
Processing and manufacturing, low cost.The bearing body 1 of the present embodiment is applicable for use with the motorcycle engine of upper and lower mould assembling structure, and right
The major and minor axle of engine is applicable.
In the present embodiment, the outer ring 2 of the bearing body 1 is provided with the annular groove 5 for installing annular element 3, the annular element 3
It is set in annular groove 5, simple structure, is easy to assembling.
In the present embodiment, the keeper 4 and annular groove 5 are located at respectively the axial both sides of bearing body 1, simple structure, arrangement
Rationally, bearing body 1 is enable to be provided simultaneously with preventing the function that axial motion and restriction are circumferentially rotated.
In the present embodiment, the annular element 3 is location collar, and simple structure is easy to processing and manufacturing, axial retention effect
It is good.
In the present embodiment, the width of the annular groove 5 is 1～2mm, and the distance of the axial end of 5 distance between bearing body of annular groove 1 is 2
～4mm, the width of the annular groove 5 of the present embodiment is 1.6+0.1mm, and the distance of the axial end of 5 distance between bearing body of annular groove 1 is 3+
0.15mm, ensures that bearing body 1 has optimal performance while ensure that assembling intensity.
In the present embodiment, the keeper 4 is cylindrical-shaped structure, in order to enter luggage with the column pin hole on crankcase
Match somebody with somebody, realize circumferentially positioned.
In the present embodiment, the bearing body 1 is needle bearing, and the needle bearing also includes the guarantor being arranged in outer ring 2
Frame 6 and needle roller 7 are held, the needle roller 7 is supported between outer ring 2 and retainer 6, with higher load-taking capacity, radial junction
Structure is compact, is particularly suited for the supporting structure of the size-constrained system of radially installed, improves assembling and performance.
Finally illustrate, above example is only unrestricted to illustrate technical scheme, although with reference to compared with
Good embodiment has been described in detail to the present invention, it will be understood by those within the art that, can be to the skill of the present invention
Art scheme is modified or equivalent, and without deviating from the objective and scope of technical solution of the present invention, it all should cover at this
