Abstract
A motorcycle thick toothed chain wheel is characterized in that a transition arc is arranged between the tooth top of the chain wheel and the corner part of a tooth socket; the tooth top coefficient of the chain wheel is higher than 8, a tooth corner angle of the chain wheel is larger than 140 degrees; and the tooth top of the chain wheel is provided with a quenching depth layer as thick as 2.0mm to 3.0mm. With the motorcycle thick toothed chain wheel, the tooth top height coefficient is reduced, and the quenching depth is enhanced, so that the phenomenon of tooth jumping is not easy to occur; and the tooth corner angle is enlarged, and the contact area between a chain rod and a tooth socket part is enlarged, so that the load carrying capability of the unit area of the chain wheel is reduced, and the service life of the chain wheel is greatly prolonged.
Description
Technical field
The utility model relates to gear, the thick toothed chain wheel of especially a kind of motor bike.
Background technology
At present the use failure mode of chain wheel of motorcycle mainly is wearing and tearing, and the main position of the wearing and tearing of sprocket wheel is the tooth portion of the gear teeth, in order to reduce the wearing and tearing of sprocket tooth part, need quench to the tooth portion of sprocket wheel, to strengthen the hardness of sprocket tooth part, strengthens resistance to abrasion.Existing chain wheel of motorcycle tooth portion is more sharp-pointed, and hardening penetration is crossed dark back spring tooth easily, and that hardening penetration is crossed shallow wearing and tearing is bigger, causes service life limited.
The utility model content
Technical problem to be solved in the utility model is, occurs the spring tooth greatly easily at hardening penetration, the little easy defective of hardening penetration, and provide a kind of motor bike thick toothed chain wheel.
In order to solve the problems of the technologies described above, the utility model provides a kind of motor bike thick toothed chain wheel, it is characterized in that: the tooth top of sprocket wheel and teeth groove corner have an excessive circular arc; The addendum coefficient of this sprocket wheel is less than 8.
The roller seating angle of sprocket wheel is greater than 140 °.
The tooth top of sprocket wheel has 2.0mm to the thick hardening penetration layer of 3.0mm.
Good effect of the present utility model is: reduced addendum coefficient, hardening penetration improves, and be not prone to spring tooth phenomenon, and gear is more wear-resisting more; Increase roller seating angle, increased the area of contact of chain rod and teeth groove part, stressed reducing on the sprocket wheel unit area, the service life of the sprocket wheel of Ti Gaoing greatly.
Description of drawings
Fig. 1 structural representation of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment the utility model is described in further detail.
As shown in Figure 1, the thick toothed chain wheel of motor bike described in the utility model, the tooth top of thick toothed chain wheel and teeth groove corner are that radius is the excessive circular arc of R1, and in the utility model, addendum coefficient is 7.9, and traditional addendum coefficient is all greater than 8.5.Gear teeth hardening penetration is brought up to 2.0mm to 3.0mm from the 0.5-2.0mm of routine, effectively reduces the possibility that the quenching crown bursts apart, and hardening penetration increases, and the gear teeth are more wear-resisting.The roller seating angle of the thick toothed chain wheel after the improvement is greater than conventional roller seating angle, chain wheel of motorcycle with 30 teeth is an example, a=140-90/Z=137 ° of conventional roller seating angle, after the improvement is 145 °, has increased the area of contact of chain rod and teeth groove part, stressed reducing on the sprocket wheel unit area, add the raising of hardening penetration, the gear teeth are more wear-resisting, and do not improve the service life of the sprocket wheel of Ti Gaoing, and cost greatly on original basis.
The foregoing description of the present utility model only is to be explanation the utility model example, and is not to be qualification to embodiment of the present utility model.For those of ordinary skill in the field, can also make other multi-form variation and changes on the basis of the above description.Here can't give exhaustive to all embodiments.Everyly belong to the row that conspicuous variation that the technical solution of the utility model amplifies out or change still are in protection domain of the present utility model.
Claims (3)
