Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is retouched in detail
It states.
A kind of gearbox structure, including shell 1, the both ends of the shell 1 have left end cap 2 and right end cap 3, described
The bottom of left end cap 2 or the right end cap 3 is equipped with raised line 6, and raised line 6 is matched with the card slot of shell 1, by using described convex
The cooperation of item 6 and the card slot, can make between left end cap 2 and shell 1, right end cap 3 and shell 1 by way of clamping engagement
Connection, and dust-proof and sealing effect can be played.
The clamping portion integrally to connect is equipped in the center of the left end cap 2 or right end cap 3, in the clamping portion
Periphery is connected with adapter sleeve 8, can make the left end cap 2 or the convenience of right end cap 3 and motor phase by using the adapter sleeve 8
Connection, convenient for integrated and assembling.
There is the gear 11 being meshed by axis connection in the inside of shell 1, left end cap 2 is connected with one end of input shaft 4, institute
The other end for stating input shaft 4 is connected by bearing with the right end cap 3, and right end cap 3 is connected with one end of output shaft 5, described
The other end of output shaft 5 is connected by bearing with the right end cap 3, and design in this way can keep balance, it is ensured that dynamic
Stationarity in power transmittance process, additionally it is possible to reduce the bearing load of output shaft 5, prolong the service life.
There is oil duct 10 in the inner wall of the shell 1, on the shell 1 there is oil outlet, connected on the oil outlet
There is oil cap 9, it, can be by fuel-displaced liquid injection hole pressure oil to oil duct 10 by from external opening oil cap 9.
The oil duct 10 is circumferentially disposed along the inner wall of the shell 1 so that oil duct 10 can be formed into a loop structure, simultaneously
Oil circuit area can be expanded.
In order to ensure the stability of shell 1, pedestal 12 is connected with by support shaft 7 in the bottom of shell 1, utilizes institute
Support can be formed by stating pedestal, convenient that shell of reduction box 1 is fixed, held stationary.
In order to ensure stability that power transmits, in the input shaft 4 or the output shaft 5 and the gear that connect
It is mutually sealed by airtight and watertight padding between 11.
By above technical scheme, gearbox structure provided by the present invention, good airproof performance transmits stationarity height, and
And service life is long.
What has been described above is only a preferred embodiment of the present invention, it is noted that for those of ordinary skill in the art
For, without departing from the concept of the premise of the invention, various modifications and improvements can be made, these belong to the present invention
Protection domain.
