Description
Technical field
The utility model relates to a kind of gear, and more particularly, it relates to a kind of basin tooth for motor.
Background technique
Motor be a kind of can the machine that can be converted into mechanical energy of other form, it is the heart of modern power element, and the basin tooth in motor is the requisite element of motor, the processing of basin tooth and the performance of precision to motor play decisive role.
Basin tooth adopts bolt or keyway to be connected with axle usually, but because engine speed is fast, so the active force between axle and basin tooth is larger, and deviation can be produced after keyway and bolt Long-Time Service, cause producing between axle and basin tooth and loosen, cause the situation such as noise and wearing and tearing to produce, have a strong impact on engine performance, and the less bad processing of width of keyway, requirement on machining accuracy is high, needs cost high.
Model utility content
For the deficiency that prior art exists, it is strong that the purpose of this utility model is to provide a kind of stability, a kind of basin tooth for motor that noise is little.
For achieving the above object, the utility model provides following technological scheme: a kind of basin tooth for motor, comprise basin tooth body, described basin tooth body comprises teeth portion, joint, described joint is provided with some tapped holes, described basin tooth body surface is provided with wearing layer, described joint offers manhole, the hole wall of described manhole offers rectangle groove, described width of rectangular accounts for 16/25 of manhole diameter, and described rectangle groove quantity is two and is symmetricly set on the hole wall of manhole.
Preferably, the turning of described rectangle groove is equipped with fillet.
Preferably, described tapped hole be symmetrically distributed in do not offer rectangle groove side joint on, described tapped hole quantity is 6.
Preferably, described joint thickness and described basin tooth body diameter ratio are 2/25.
Preferably, described teeth portion and joint contacting point are provided with transition slot.
By adopting technique scheme, the hole wall of manhole is provided with rectangle groove, this width of rectangular is large, easy to process, and this rectangle groove can also be used to fixing basin tooth body, time fixing, expanding fixture is placed in rectangular opening place, expanding fixture is expanded just basin tooth body to be fixed, facilitate fine finishing basin tooth teeth portion, and due to rectangle groove larger, supporting has larger protrusion with the axle of this basin tooth body fits, protrude and match with rectangle groove, during due to work, rectangular opening lifting surface area is larger, not easily there is deformation and deviation, be conducive to the stability that basin tooth body works long hours, also wear phenomenon can not be produced, engine performance is increased, utilize the tapped hole be arranged on joint basin tooth body and axle supporting with it firmly can be fixed simultaneously, avoid collision when there is gap therebetween, add fixing stability, reduce noise and wearing and tearing.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the worm's eye view of the utility model embodiment;
Fig. 2 is the left view of the utility model embodiment;
Fig. 3 is the A place enlarged view of the utility model embodiment.
Reference character: 1, basin tooth body, 2, rectangle groove, 3, tapped hole, 4, transition slot.
Embodiment
With reference to accompanying drawing, the utility model embodiment is described further.
As shown in Figure 1, a kind of basin tooth for motor, comprise basin tooth body 1, described basin tooth body 1 comprises teeth portion, joint, described joint is provided with some tapped holes 3, described basin tooth body 1 surface is provided with wearing layer, described joint offers manhole, the hole wall of described manhole offers rectangle groove 2, described rectangle groove 2 width accounts for 16/25 of manhole diameter, described rectangle groove 2 quantity is two and is symmetricly set on the hole wall of manhole, in order to driving error can not be there is because of the increase of service time when ensureing body 1 transmission of basin tooth, need to make requirement to basin tooth and the axle that matches with it, manhole hole wall is offered rectangle groove 2, bump contact area on rectangle groove 2 and the axle that matches with it is large, and active force is therebetween constant, cause the stressed reduction of per unit volume, not easily there is deformation in the two, the two is coordinated stable, when rectangle groove 2 width accounts for 16/25 of manhole diameter, stable drive can be reached, the objects such as convenient manufacture, the weight of basin tooth body 1 is reduced under the condition of proof strength, provide cost savings.
The hardened layer of wearing layer to be thickness be 0.9-1.3mm, obtain through over carburizing quenching heat treatment after basin tooth body 1 processes, heat treatment posterior basin tooth body 1 surface hardness reaches 58-63HRC, and core hardness reaches 33-48HRC, plays the effect preventing basin tooth body 1 from wearing and tearing in using.
The turning of described rectangle groove 2 is equipped with fillet, and because rectangle has sharper corner angle, when causing transmission, faceted portions easily weares and teares, and by being provided with fillet, corners is smooth inclined-plane, makes can not produce wearing and tearing during transmission, and production and processing is convenient.
Described tapped hole 3 be symmetrically distributed in do not offer rectangle groove 2 side joint on, described tapped hole 3 quantity is 6, due to manhole hole wall offering rectangle groove 2, basin tooth body 1 is made to offer rectangle groove 2 place thinner, the stress-bearing capability at this place will be greatly reduced as offered tapped hole 3 more herein, for this reason, tapped hole 3 is arranged on the side that joint does not offer rectangle groove 2, while ensureing fixed demand, ensure that the strength of gear teeth.
Described joint thickness and described basin tooth body 1 diameter ratio are 2/25, in order to the weight controlling basin tooth needs there is strict requirement to the thickness of joint, but the demand of joint intensity must be met again, when joint thickness and described basin tooth body 1 diameter ratio are 2/25, can both annex, meet weight demands while proof strength, reduce the use of material, reduce cost.
As Figure 2-3, described teeth portion and joint contacting point are provided with transition slot 4, in basin tooth body 1 finishing passes, need to process further the tooth of basin tooth, but because the distance between tooth and joint is little, easily scratch when processing tooth joint, need higher processing technology for this reason, add processing cost, in order to cut down finished cost, transition slot 4 is provided with in teeth portion and joint contacting point, can not be scratched during such processing teeth portion joint, the use of material is decreased under the prerequisite of transition slot 4 proof strength is set simultaneously, reduce cost of production.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
