Abstract
The utility model discloses an engine output sprocket wheel and consists of a sprocket wheel body (1). The sprocket wheel body (1) is provided with a lug boss (2) extending outwards at one end surface. The lug boss (2) is provided with a spline hole (3) at the center. The spline hole outside (3) is distributed with installment holes (4). The utility model guarantees the stable and reliable transmission for the chain when the rear wheel of a motorcycle is enlarged in the size, effectively avoids generating suspension of the engine output shaft body, prevents the output shaft from distortion because of the suspension of the shaft body, can greatly enhances the service life of the output shaft and has the advantages of reasonable design, simple structure and easy application.
Description
Technical field
The utility model belongs to technical field of motorcycles, specifically, relates to a kind of output sprocket wheel of motorcycle engine.
Background technique
Output sprocket wheel of motorcycle engine is sleeved on the spline of engine output shaft by the splined hole at its center, spline position at output shaft is provided with an annular groove, the sprocket wheel baffle plate is inserted in the annular groove of spline and rotates to an angle, the internal spline of sprocket wheel baffle plate center hole and the external splines on the output shaft are misplaced in the axial direction, by bolt sprocket wheel baffle plate and output sprocket are fixed together then, output sprocket and sprocket wheel baffle plate are fixed on the engine output shaft like this, when engine operation, output sprocket rotates with output shaft, and by the coaxial driven sprocket rotation of chain drive and motor cycle rear wheel, motorcycle to overtake.For making chain transmission steady, should ensure that generally output sprocket and driven sprocket are positioned at same vertical surface.But the vehicle that has is according to the needs of Environmental Conditions or other reason, and the width of trailing wheel is suitably increased, and promptly outer moving is taken place in the mounting point of driven sprocket.For the outer phase shift with driven sprocket adapts to, the corresponding lengthening of engine output shaft, the mounting point of output sprocket is also outer simultaneously moves.The axle body of engine output shaft between motor and output sprocket is unsettled like this, and output shaft is easily from this unsettled deforming, thereby causes rotating not steady, influences the performance of whole chain driving mechanism.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of motor output sprocket that can prevent effectively that engine output shaft from deforming because of the part axle body is unsettled.
The technical solution of the utility model is as follows: a kind of motor output sprocket, comprise sprocket body, its key is: an end face of described sprocket body is extended with boss laterally, and the center of this boss has splined hole, is distributed with mounting hole in the outside of splined hole.
The utility model be according to motor cycle rear wheel widen, with the coaxial driven sprocket mounting point of trailing wheel outside move the improvement of doing, the mounting type of output sprocket is identical with background technique, after being installed on the engine output shaft, boss on the sprocket body makes the axle body between motor and the output sprocket chain disc portion no longer unsettled over against motor; The size that the height of boss and motor cycle rear wheel are widened adapts, and makes the chain disc portion of sprocket body and driven sprocket be positioned at same vertical surface.Like this when guaranteeing the steady transmission of chain, under the effect of boss, prevented that effectively engine output shaft from deforming because of the part axle body is unsettled, thereby ensured the reliable performance of whole chain driving mechanism, prolonged the working life of engine output shaft greatly.
For alleviating the weight of output sprocket, and be convenient to install the sprocket wheel baffle plate, have groove on the end face of boss dorsad in above-mentioned sprocket body, this groove communicates with splined hole and mounting hole respectively.
Beneficial effect: when the utility model strengthens at the motor cycle rear wheel width dimensions, can ensure that chain transmission steadily, reliably, and effectively avoided the axle body of engine output shaft to take place unsettled, prevented that output shaft is out of shape because of axle body is unsettled, improve the working life of output shaft greatly, had characteristics such as reasonable in design, simple in structure, that enforcement is easy.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1 and Figure 2, the utlity model has sprocket body 1, on an end face of sprocket body 1, have groove 5, for placing the sprocket wheel baffle plate; Another end face of sprocket body 1 one laterally is extended with boss 2, the center of this boss 2 have with engine output shaft on the splined hole 3 that adapts of external splines, be symmetrically distributed with two mounting holes 4 in the outside of splined hole 3.Described splined hole 3 and mounting hole 4 connect to the bottom surface of groove 5 from the end face of boss 2 respectively.
In the utility model, the height of boss 2 a large amount of determines according to adding of motor cycle rear wheel width dimensions, make be in place after, the chain disc portion of sprocket body 1 and the driven sprocket on the rear-wheel spindle are positioned at same vertical surface; And because the existence of boss 2, the axle body between the chain disc portion of motor and sprocket body 1 can be not unsettled, prevents that engine output shaft is because of the unsettled purpose that deforms of part axle body thereby reach.
Claims (2)
1, a kind of motor output sprocket, comprise sprocket body (1), it is characterized in that: an end face of described sprocket body (1) is extended with boss (2) laterally, and the center of this boss (2) has splined hole (3), is distributed with mounting hole (4) in the outside of splined hole (3).
2, motor output sprocket according to claim 1 is characterized in that: have groove (5) on the end face of boss (2) dorsad in described sprocket body (1), this groove (5) communicates with splined hole (3) and mounting hole (4) respectively.
