Abstract
The utility model relates to an efficient non-circular-gear hydraulic motor which comprises a front housing, a back housing, an inner gear ring and a spindle, wherein the inner gear ring is internally provided with a non-circular center gear matched with the inner gear ring; a plurality of planetary gears are arranged between the non-circular center gear and the inner gear ring; a plurality of matched oil holes are formed in the two end faces of the non-circular center gear respectively; and circular side plates are arranged on the two sides of the inner gear ring and the non-circular center gear respectively. The efficient non-circular-gear hydraulic motor has the benefits that with the adoption of the efficient non-circular-gear hydraulic motor, good lubricating effects among the inner gear ring and the side plates, and among the non-circular center gear and the side plates are achieved; the side plates are made of ceramics, and have good wear resistance; and the service life of the hydraulic motor can be prolonged.
Description
Technical field
The utility model relates to a kind of efficient noncircular gear oil hydraulic motor.
Background technique
Existing hydraulic motor of non-circular planetary gear system mainly includes front case, rear case, non-circular gear series and main shaft, in non-circular gear series, ring gear inside is provided with the central gear of corresponding sides number, evenly be provided with planet wheel therebetween, in the train formed at ring gear, central gear and planet wheel, axially both ends of the surface are because element perpendicularity precision is difficult to assurance, although easy to process, but easily make the wheel of running produce lateral force, cause wearing and tearing, and can be in operation and produce compression shock and blind spot, cause the generation of noise, and volumetric efficiency can decline to a great extent; So now be badly in need of the noncircular gear oil hydraulic motor of the strong and long service life of a kind of wear-resistant, lubricity.
The model utility content
The purpose of this utility model is to provide a kind of efficient noncircular gear oil hydraulic motor, overcomes wear-resistant in existing product and poor lubricity, causes product short deficiency in working life.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of efficient noncircular gear oil hydraulic motor, comprise front case, rear case, ring gear and main shaft, be provided with the non-round central gear matched with ring gear in described ring gear, be provided with some planetary pinions between non-round central gear and ring gear, be evenly distributed with some assembly oilholes on non-round central gear both ends of the surface, described ring gear and non-round central gear both sides are respectively equipped with circular side panel, and circular side panel is ceramic side plate.
Further, be equipped with compensated loop between circular side panel and front case, rear case.
Further, described non-round central gear both ends of the surface are equipped with lubrication groove, and the root circle of non-round central gear is provided with the lubrication hole communicated with lubrication groove; Be provided with the compensated loop matched in described lubrication groove.
The beneficial effects of the utility model are: a kind of efficient noncircular gear oil hydraulic motor that the utility model provides, there is good lubrication effect between ring gear and non-round central gear and side plate, simultaneously, side plate adopts ceramic side plate, there is good wear resistance, can extend the working life of oil hydraulic motor.
The accompanying drawing explanation
Below with reference to the accompanying drawings the utility model is described in further detail.

Embodiment
As Figure 1-4, the described a kind of efficient noncircular gear oil hydraulic motor of the utility model embodiment, comprise front case 1, rear case 2, ring gear 3 and main shaft 4, be provided with the non-round central gear 5 matched with ring gear 3 in described ring gear 3, be provided with some planetary pinions 6 between non-round central gear 5 and ring gear 3, be evenly distributed with some assembly oilholes 10 on non-round central gear 5 both ends of the surface, described ring gear 3 is respectively equipped with circular side panel 11 with non-round central gear 5 both sides.Be equipped with compensated loop 7 between circular side panel 11 and front case 1, rear case 2.Described non-round central gear 5 both ends of the surface are equipped with lubrication groove 8, and the root circle of non-round central gear 5 is provided with the lubrication hole 9 communicated with lubrication groove 8; Be provided with the compensated loop 7 matched in described lubrication groove 8.
During use, circular side panel 11 on rear case 2 is for joining oily side plate, circular side panel 11 on front case 1 is common side plate, two side plates all adopt ceramic material, there is high abrasion and self lubricity, therefore be difficult for being worn, long service life, rear case 2 and join between oily side plate and front case 1 and common side plate between compensated loop 7 can compensator or trimmer pressure.
Hydraulic oil directly enters lubrication groove 8 by lubrication hole 9, by the side of 8 pairs of non-round central gears 5 of lubrication groove and the surface of circular side panel 11, be lubricated, generate oil film in the process of non-round central gear 5 runnings, it is less that gap between non-round central gear 5 and circular side panel 11 processes, make the oil film of side can guarantee to lubricate, can guarantee that again sealing lets out in preventing, lubrication groove 8 is interior simultaneously can arrange compensated loop 7, compensated loop 7 has self-lubricating function, and can auxiliary seal.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation on its shape or structure; every have identical with a application or akin technological scheme, within all dropping on protection domain of the present utility model.
