Abstract
The utility model relates to a driven gear structure of a variable-speed coupler. The driven gear structure comprises a driving gear and a driven gear which are engaged with each other. The driven gear structure is characterized in that the driven gear sleeves an end portion of an oil pump shaft sleeve. At least two bearings sleeve the oil pump shaft sleeve. A spacer bush is arranged between each two adjacent bearings. The bearings and the spacer bush are respectively fixed by shaft retainer rings. An oil pump bearing seat is fixedly connected with a box body. The oil pump shaft sleeve and the bearings on the same are coaxially assembled in the oil pump bearing seat. An oil pump is fixed on the oil pump bearing seat, and an input shaft of the oil pump is coaxially assembled in the oil pump shaft sleeve. The driven gear structure is easy to forge and manufacture, reliable in size and position accuracy, low in manufacturing and maintaining costs and convenient to detach and maintain.
Description
Technical field
The utility model relates to a kind of oil pump gear drive mechanism of speed regulation type hydrodynamic coupler.
Background technique
Speed regulation type hydrodynamic coupler is that liquid is a kind of dydraudynamic drive unit of medium transmitted power, and it is for example arranged on, between motor and working machine (blower fan, water pump), can be in the situation that motor speed be constant the rotating speed of step-less adjustment working machine.
The oil pump transmission structure of known speed regulation type hydrodynamic coupler as shown in Figure 1, comprises driving gear 1, driven gear 2, bearing 3, oil pump shaft bearing 4, shaft block ring 5, casing 6, pump plate 7, oil pump 8 and key 9.Its working principle is: driving gear 9 and driven gear 2 to gear oil pump, work oil pump transmission of power under declared working condition.Gear, bearing are driving mechanism, after using after a while, and can be because various factors causes gear, bearing fit partly to wear and tear, lost efficacy.
Summary of the invention
The purpose of this utility model is to provide the oil pump gear drive mechanism of a kind of easy processing, easy assembling, easy care.
In order to achieve the above object, the technical solution of the utility model has been to provide a kind of driven gear structure of regulable speed type Coupler, comprise intermeshing driving gear and driven gear, it is characterized in that, driven gear is sheathed on the end of engine oil pump shaft sleeve, at least two bearing housings are located at outside engine oil pump shaft sleeve, between adjacent two bearings, be provided with spacer, bearing and spacer are fixed by shaft block ring, oil pump shaft bearing and casing are connected and fixed, engine oil pump shaft sleeve and on coaxial bearing be assemblied in oil pump shaft bearing, oil pump is fixed in oil pump shaft bearing, the input shaft of oil pump is coaxially assemblied in engine oil pump shaft sleeve.
Preferably, described driven gear and described engine oil pump shaft sleeve coaxially assemble by key one, and fix by cover plate.
Preferably, the input shaft of described oil pump coaxially assembles by key two and described engine oil pump shaft sleeve.
Preferably, described oil pump shaft bearing is through hole for the endoporus of described bearing is installed.
Preferably, described driven gear adopts flange-type structure.
Preferably, in described oil pump shaft bearing, have the bearing oil spill port of inclination.
The utility model has changed original driven gear structure, oil pump shaft holder structure, increases engine oil pump shaft sleeve, spacer ring, cover plate, key, and its tool has the following advantages:
1, the profile that changes driven gear, changes former boss type into flange-type, forging, easy processing, and dimensional accuracy, positional accuracy easily guarantee, have reduced low cost of manufacture;
2, increase engine oil pump shaft sleeve, easy to process, assemble simple with driven gear, oil pump;
3, by step hole, change the bearings mounted endoporus of oil pump shaft bearing into through hole, it is convenient to process, measure, and changes bearing oil spill port into inclined hole, makes oil return more unimpeded;
No matter 4 is gear wears, or engine oil pump shaft sleeve wearing and tearing, can not use, as long as repair or more gear changing, engine oil pump shaft sleeve just can, dismantle, easy to maintenance, maintenance cost is low.
Accompanying drawing explanation
Fig. 1 is former speed regulation type hydrodynamic coupler oil pump gear drive mechanism schematic diagram;
Fig. 2 is speed regulation type hydrodynamic coupler oil pump gear drive mechanism schematic diagram of the present utility model.
Embodiment
For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
As shown in Figure 2, the assembly process of the driven gear structure of a kind of regulable speed type Coupler that the utility model provides is: key 1 is placed on engine oil pump shaft sleeve 10 and press-fits the driven gear 2 into flange-type structure, and fixing with screw and cover plate 14.Spacer 11 between two bearings 3 and two bearings 3 is inserted in respectively to engine oil pump shaft sleeve 10, fixing with shaft block ring 5.Oil pump shaft bearing 12 is contained on casing 6, be screwed, again the driven gear assembly installing is packed in oil pump shaft bearing 12, rotate driving gear 1, whether the engagement of seeing itself and driven gear 2 is normal, finally with screw, oil pump 8 is contained in oil pump shaft bearing 12, the input shaft of oil pump 8 coaxially assembles by key 29 and engine oil pump shaft sleeve 10.Oil pump shaft bearing 12 is through hole for the endoporus of described bearing 3 is installed, and has the bearing oil spill port 15 of inclination in described oil pump shaft bearing 12.
The utility model is compared with original structure, has increased engine oil pump shaft sleeve 10, spacer 11, cover plate 14 and key 1, and manufacture, installation, maintenance are conveniently.
