Abstract
The utility model discloses a separable gear oil pump device, consisting of a gear oil pump, a pump base, an operating rod, a gear sleeve, a belt pulley, a spline shaft rotating cover, a bearing and a small bearing, wherein the spline shaft rotating cover is fixed with the belt pulley into a whole, the bearing and the small bearing are arranged on the belt pulley, the center of the spline shaft rotating cover is fixedly connected on a spline shaft, and the spline shaft is positioned in an inner hole of the journal of the pump base by the small bearing and is positioned at the same axis of a spline shaft head of the gear oil pump; the periphery of the spline shaft rotating cover is fixedly connected on the belt pulley which is arranged on the journal of the pump base by a built-in bearing and can rotate freely; and a key groove is processed at the outer end of the gear sleeve and the gear sleeve can be meshed and separated with the key shaft. The separable gear oil pump device has smaller size and compact structure.
Description
Technical field
The utility model relates to the gear oil pump device of a kind of tractor with small four wheels and agricultural vehicle use, but especially a kind of gear oil pump device of clutch.
Background technique
The gear oil pump device that existing tractor with small four wheels and agricultural vehicle adopt, but the band clutch structure that has, what have is not with clutch structure.The gear oil pump device of band clutch structure comprises pump seat, be installed in the gear oil pump that has spline axle head on the pump seat, be contained in the key axle in the endoporus of axle journal of pump seat and be contained in belt pulley on the key axle, because belt pulley is contained in and is positioned on the key axle, cause the axial dimension of key axle to become big, thereby caused the volume of the gear oil pump device of band clutch structure to become big, because the volume of the gear oil pump device of existing band clutch structure is big, therefore, caused its mounting arrangements on tractor with small four wheels and agricultural vehicle not too reasonable, for example, existing tractor with small four wheels majority is with on the irrational protecgulum that is installed in gear box of tractor of gear oil pump device.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of volume is less, the gear oil pump device of a kind of clutch of compact structure but provide, to overcome the structural imperfection that prior art exists.
The technical solution adopted in the utility model is: but the gear oil pump device of clutch by gear oil pump, pump seat, operating handle and engagement cover, belt pulley and the key axle hub cap that is fixed with one and on bearing and little bearing form, its structural feature is: the center of a, key axle hub cap is fixed on the key axle, the key axle is positioned at by little bearing in the endoporus of axle journal of pump seat, and is positioned at the coaxial position of the spline axle head of gear oil pump; The periphery of b, key axle hub cap is connected on the belt pulley, and the Bearing Installation of belt pulley by interior dress is on the axle journal of pump seat, and belt pulley can freely rotate along axle journal; C, place, engagement cover outer end are processed with keyway, can be meshed with the key axle and separate.
After adopting said structure, because belt pulley is installed on the axle journal of pump seat, rather than is installed on the key axle, therefore shortened the axial length of key axle, but thereby dwindled the axial length of the gear oil pump device of whole clutch, brought that volume is less, the advantage of compact structure.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
As shown in drawings, the utility model is made up of bolt 1, hole back-up ring 2, bearing 3, little bearing 4, bolt 5, gear oil pump 6, engagement cover 7, pump seat 8, operating handle 9, pin 10, belt pulley 11, shaft retaining ring 12, key axle hub cap 13.The center of key axle hub cap 13 is fixed on the key axle, and the key axle is contained in by little bearing 4 in the endoporus (among the figure shown in the b) of the axle journal of pump seat 8, with the spline axle head that guarantees key axle hub cap 13 and gear oil pump 6 (among the figure shown in the d) on coaxial line.Belt pulley 11 is contained on the axle journal (among the figure shown in the c) of pump seat 8 by bearing 3, belt pulley 11 can freely rotate along the axle journal of pump seat 8, bearing 3 is positioned by shaft retaining ring on the axle journal that is installed on pump seat 8 12 and the hole back-up ring 2 that is installed in belt pulley 11 endoporus, and the periphery of axle hub cap 13 is connected on the belt pulley 11 by bolt 1.Operating handle 9 is positioned on the pump seat 8 by pin 10, and gear oil pump 6 is connected on the pump seat 8 by bolt 5, and engagement cover 7 slide keys are connected on the spline axle head (among the figure shown in the d) of gear oil pump 6.Hole among the figure shown in a is used for the utility model overall fixed and connects.During work, belt pulley 11 drives the key axle hub cap 13 that is fixed with one with it and rotates simultaneously, and then drives the rotation of key axle, stirs engagement cover 7 spline axle heads along gear oil pump 6 by operating handle 9 and moves, make engagement cover 7 with the engagement of key axle or separate, to realize the various working staties of gear oil pump 6.
