Abstract
The utility model discloses a floating type side plate on a gear oil pump. The floating type side plate comprises a pump body, wherein a driving shaft and a driven shaft are mounted in an inner cavity of the pump body; a driving gear is mounted on the driving shaft; a driven gear meshed with the driving gear is mounted on the driven shaft; a front cover and a rear cover are mounted at a left end and a right end of the pump body respectively; the driving shaft and the driven shaft are sleeved with a layer of a DU (depleted uranium) lining respectively; the side plate is arranged between the front end and the rear end and the driving gear and the driven gear in the pump body; the DU lining is sleeved with the side plate in a floating manner; and a layer of an E-shaped cushion is arranged between the front cover and the side plate and between the rear cover and the side plate. The floating type side plate is simple in structure; the DU lining is arranged in the pump body, so that floating type installation of the side plate is realized, and the gears can rotate conveniently; and the floating type side plate has a better silencing effect.
Description
Technical field
The utility model relates to gear oil pump, is mainly the floating type side plate on a kind of gear oil pump.
background technique
The side plate arranging between front/rear cover and gear on the gear oil pump of existing use is all fixed installation, do not have the side plate with floatability energy is installed, thereby the shared volume of pump housing internal gear is fixing limited, affects working gear in practical operation.。
Model utility content
Technical problem to be solved in the utility model is to provide the floating type side plate on a kind of gear oil pump, and it is simple in structure, is provided with DU lining and makes the floating type installation of side plate in the pump housing, facilitate gear rotation work, and the noise elimination effect of floating type side plate is better.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
Floating type side plate on a kind of gear oil pump, include the pump housing, driving shaft and driven shaft are installed in pump housing inner chamber, driving gear is installed on driving shaft, the driven gear being meshed with driving gear is installed on driven shaft, a left side for the described pump housing, right-hand member is separately installed with protecgulum and bonnet, it is characterized in that: described driving shaft and driven shaft are respectively installed with one deck DU lining outward, before described pump housing inherence, between bonnet and driving gear and driven gear, be provided with side plate, described side plate floating bushing is contained in outside DU lining, described protecgulum, between bonnet and side plate, be respectively equipped with one deck E type pad.
The utility model has the advantages that:
The utility model is simple in structure, is provided with DU lining and makes the floating type installation of side plate in the pump housing, facilitate gear rotation work, and the noise elimination effect of floating type side plate is better.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
