Description
Technical field
The utility model belongs to deceleration transmission technical field, and in particular to a kind of input shafting of transmission case.
Background technique
With the development of modern industrial technology, the technical performance and economic indicator of mechanical driving device are proposed increasingly
High requirement, under this form, have many advantages, such as transmission ratio it is big, from heavy and light, large speed ratio gear transmission speed reducer small in size
It is applied widely.
It is mainly to rely on to be formed by swept volume variation between pumping cylinder and meshing gear and move that existing gear, which has oil pump,
Conveying liquid is allowed to the drum pump being pressurized.Belt wheel in the prior art is directly keyed with input shaft, mistake of the belt wheel in rotation
Cheng Zhonghui is applied to the biggish axially and radially torque of input shaft, can thus make the cooperation surface wear of input shaft and the pump housing compared with
Greatly, the service life of oil sealing and bearing is lower, and gear can be also prone to wear, and has abnormal sound.
Utility model content
The purpose of the utility model is to provide a kind of input shafting of transmission case, realize that input shaft circular runout minimizes,
And then the service life of bearing and oil sealing is promoted, reduce gear wear.
The utility model provides the following technical solution:
A kind of input shafting of transmission case, including input shaft, the input shaft are equipped with gear, the institute of the gear two sides
It states and is respectively equipped with bearing on input shaft, one end of the input shaft is equipped with oil pump, and oil is equipped between the oil pump and the bearing
Envelope, between the oil sealing and the oil pump be equipped with screw coupling, be successively arranged between the oil sealing and the bearing disc spring and
Cushion.
Preferably, throttling plug screw is equipped between the oil sealing and the input shaft.
Preferably, the screw coupling periphery is equipped with coupler casing.
Preferably, it is equipped between the coupler casing and the oil pump and helps set.
Preferably, tubular heat exchanger is equipped in the oil pump.
Preferably, the oil pump is equipped with relief valve.
The beneficial effects of the utility model are: bearing controls by the tensioner stress of disc spring and selects working stress big
It is small, and reach its working stress value under the premise of not influencing bearing service life, the actual bearer ability of Lai Shixian bearing into
One step is promoted, and realizes that input shaft circular runout minimizes, and then promote the service life of bearing and oil sealing；Oil sealing and bearing it
Between add cushion, make bearing without working gap, run more stable；The design of shell screw coupling, has auxiliary to the reflux of oil liquid
Effect；Tubular heat exchanger is implanted into inside oil pump, the requirement that design installation space external equipment of effective solution saves
Installation space is saved.
Detailed description of the invention
Attached drawing is used to provide a further understanding of the present invention, and constitutes part of specification, practical with this
Novel embodiment is used to explain the utility model together, does not constitute limitations of the present invention.In the accompanying drawings:
Fig. 1 is the utility model structure diagram；
In the figure, it is marked as 1. input shafts；2. gear；3. bearing；4. oil pump；41. tubular heat exchanger；42. relief valve；5.
Throttle plug screw；6. oil sealing；7；Screw coupling；8. cushion；9. disc spring；10. coupler casing；11. helping set.
Specific embodiment
As shown in Figure 1, a kind of input shafting of transmission case, including input shaft 1, input shaft 1 is equipped with gear 2,2 liang of gear
Bearing 3 is respectively equipped on the input shaft 1 of side, one end of input shaft 1 is equipped with oil pump 4, oil sealing 6 is equipped between oil pump 4 and bearing 3,
Throttling plug screw 5 is equipped between oil sealing 6 and input shaft 1.Screw coupling 7 is equipped between oil sealing 6 and oil pump 4, outside screw coupling 7
It encloses and is equipped with coupler casing 10, be equipped between coupler casing 10 and oil pump 4 and help set 11, further keep its stable operation.
Disc spring 9 and cushion 8 are successively arranged between oil sealing 6 and bearing 3.
Further, it is equipped with tubular heat exchanger 41 in oil pump 4, is implanted into fuel tank internal, effective solution sets outside
The standby requirement to installation space design.Oil pump 4 is equipped with relief valve 42, and the requirement to flow and oil are realized by pressure control
Lower than the selection of pressure value.
As shown in Figure 1, a kind of input shaft system of transmission case is in use, dish is successively arranged between oil sealing 6 and bearing 3
Spring 9 and cushion 8 after increasing disc spring 9, make to fill an input shaft 1 more stability, existing bearing and gear are prone to wear, have different
It rings, present disc spring 9 makes it in no lash state, and then keeps whole safety driving；Meanwhile bearing 3 need it is certain
Pre- police strength increases cushion 8, according to input, adjusts the thickness of cushion 8, bearing 3 is made to keep certain pre- police strength.The transmission of one highest wisdom
The output torque of device is big, then volume is bigger, and torque is big while small in size if necessary, using the design of disc spring 9, in heavy type
In equipment, the mode of hydraulic piston is taken, it can be achieved that output torque is big while small in size.Bearing 3 is set without working gap structure
Meter, controls by the tensioner stress of disc spring 9 and selects working stress size, and reaching its working stress value is not influencing bearing
Under the premise of 3 service lifes, the actual bearer ability of Lai Shixian bearing 3 is further promoted, and realizes 1 circular runout of input shaft most
Smallization, and then promote the service life of bearing 3 and oil sealing 6.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, although ginseng
The utility model is described in detail according to previous embodiment, it for those skilled in the art, still can be with
It modifies the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features.It is all
Within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in practical
Within novel protection scope.
