Abstract
The utility model discloses a kind of gear for gear box, including gear, the external peripheral surface of described gear is evenly arranged with multiple external gear teeth, there is between the adjacent gear teeth outer teeth groove；The centre position of described gear is machined with gear hole, is provided with internal gear body on the inwall of described gear hole, is evenly arranged with multiple interior gear teeth, has internal spline between the adjacent interior gear teeth on the inwall of described internal gear body；And on the lateral surface of described gear, it is provided with multiple boss.This utility model simple in construction, reasonable in design and easy for installation, it is possible to facilitate change speed gear box work to collect gearshift, and the structural strength of whole gear can be improved, increase its service life.
Description
Technical field
This utility model relates to change speed gear box technical field, particularly relates to a kind of gear for gear box.
Background technology
Change speed gear box generally refers to the change speed gear box of automobile.It is divided into manual, automatic two kinds, and manual transmission is mainly by gear
Form with axle, produce variable-speed torque-converting by different gear combination；And automatic gear-box AT is by hydraulic torque converter, planetary gear
Form with hydraulic control system, by the way of fluid power transmission and gear combination, reach variable-speed torque-converting.Function is: one, change
Gear ratio；Two, in the case of hand engine rotation is constant, automobile is made can to fall back traveling；Three, utilize neutral, interrupt power and pass
Pass, to enable the engine to starting, idling, and be easy to shifting of transmission or carry out power output.
Change speed gear box its be mainly made up of gear box casing and each internal geared parts, current gear for gear box exists
During use, due to long fretting wear, reducing its service life and structural strength, synchronization do not installed by gear simultaneously
Device, badly influences gearshift during operation.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of gear for gear box.
This utility model is to be achieved through the following technical solutions:
A kind of gear for gear box, including gear, is evenly arranged with on the external peripheral surface of described gear
Multiple external gear teeth, have outer teeth groove between the adjacent gear teeth；The centre position of described gear is machined with gear hole, described
It is provided with internal gear body on the inwall of gear hole, the inwall of described internal gear body is evenly arranged with multiple interior gear teeth,
Between the adjacent interior gear teeth, there is internal spline；And on the lateral surface of described gear, it is provided with multiple boss.
As optimal technical scheme of the present utility model, the two ends of described external gear teeth are provided with chamfering.
As optimal technical scheme of the present utility model, described external gear teeth is machined with rectangular channel.
As optimal technical scheme of the present utility model, the quantity of described boss is between six, and adjacent boss
Apart from equal.
Compared with prior art, the beneficial effects of the utility model are: this utility model simple in construction, reasonable in design and
Easy for installation, it is possible to facilitate change speed gear box to work and collect gearshift, and the structural strength of whole gear can be improved, increase it and use the longevity
Life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.
Referring to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of gear for gear box, including gear 1, on the external peripheral surface of described gear 1 uniformly
It is provided with multiple external gear teeth 2, there is between the adjacent gear teeth 2 outer teeth groove 3；The centre position of described gear 1 is machined with tooth
Wheel bore 4, is provided with internal gear body 5 on the inwall of described gear hole 4, uniformly sets on the inwall of described internal gear body 5
It is equipped with multiple interior gear teeth 6, between the adjacent interior gear teeth 6, there is internal spline 7；And arrange on the lateral surface of described gear 1
There is multiple boss 8.
The two ends of described external gear teeth 2 are provided with chamfering 21, and described external gear teeth 2 is machined with rectangular channel 9.
In the present embodiment: the quantity of described boss 8 is six, and the distance between adjacent boss 8 is equal.
In sum, this utility model simple in construction, reasonable in design and easy for installation, it is possible to facilitate change speed gear box work to collect
Gearshift, and the structural strength of whole gear can be improved, increase its service life.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model
Protection domain within.
