Description
Technical field
This utility model is related to change speed gear box technical field, more particularly, to a kind of change speed gear box shell.
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
With axle composition, variable-speed torque-converting is produced by different gear combination；And automatic gear-box AT is by hydraulic torque converter, planetary gear
With hydraulic control system composition, by way of fluid power transmission and gear combination, to reach variable-speed torque-converting.Function is：First, change
Gear ratio；2nd, in the case of hand engine rotation is constant, so that automobile is fallen back and travel；3rd, 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, existing gear box casing is in peace
It is difficult to ensure that concentricity between two housings during dress, after when concentricity cannot ensure in certain limit value, change speed gear box installs
Oil leakage phenomenon can be formed, thus affecting the work of change speed gear box.The service life of existing gear box casing is relatively low simultaneously, thermal diffusivity
Can be poor.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of change speed gear box shell.
This utility model is to be achieved through the following technical solutions：
A kind of change speed gear box shell, including housing, described housing is in integrally truncated cone-shaped structure, sets in the upper end of described housing
It is equipped with multiple radiating grooves, and the external process in described radiating groove has multiple connecting holes；Add in the lateral part lower end of described housing
Work has multiple screw holes；And it is provided with modal circumferential stiffening rib on the lateral part lower circumferential direction of described housing.
As optimal technical scheme of the present utility model, the upper end centre position of described housing offers axially position hole.
As optimal technical scheme of the present utility model, the upper end diameter of described housing is less than lower end diameter, and described
It is provided with fin outside the upper end of housing.
As optimal technical scheme of the present utility model, described modal circumferential stiffening rib and housing are integrally formed setting, and described
Modal circumferential stiffening rib is made using metal material.
Compared with prior art, the beneficial effects of the utility model are：This utility model structure simple, reasonable in design and
Easy for installation, screw hole is provided with Positioning screw, controls the position of two housings using Positioning screw, so that change speed gear box is existed
Can be good at when installation controlling two housing concentricitys, thus preferably preventing shell from installing rear oil leak, leading to simultaneously
Cross and be provided with radiating groove, it is possible to increase its radiating effect, be provided by modal circumferential stiffening rib and fin, it is possible to increase its structure is strong
Degree, strengthens its service life.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.It 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.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
A kind of described change speed gear box shell, including housing 1, described housing 1 is overall to be in truncated cone-shaped structure, in described housing 1
Upper end be provided with multiple radiating grooves 2, and the external process in described radiating groove 2 has multiple connecting holes 3；In described housing 1
Lateral part lower end is machined with multiple screw holes 4；And ring reinforcement is provided with the lateral part lower circumferential direction of described housing 1
Muscle 5.
The upper end centre position of described housing 1 offers axially position hole 6, and the upper end diameter of described housing 1 is less than lower end
Diameter, and it is provided with fin 7 outside the upper end of described housing 1, described modal circumferential stiffening rib 5 is integrally formed setting with housing 1, and
Described modal circumferential stiffening rib 5 is made using metal material.
When using, in screw hole 4, Positioning screw is installed, controls the position of two housings using Positioning screw,
Change speed gear box is made to can be good at controlling two housing concentricitys when installing, thus leaking after preferably preventing shell from installing
Oil, is provided by radiating groove 2 simultaneously, it is possible to increase its radiating effect, is provided by modal circumferential stiffening rib 5 and fin 7, can
Improve its structural strength, strengthen its service life.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all this
Any modification, equivalent and improvement made within the spirit of utility model and principle etc., should be included in this utility model
Protection domain within.
