Problems solved by technology

Therefore, under the same sealing gap conditions, the leakage of the emulsion will far exceed the leakage of mineral oil, which will lead to a sharp drop in the working pressure and volumetric efficiency of the hydraulic motor, and even make it unusable.
[0005] 2. Compared with mineral oil, the emulsion does not have a good lubricating function, which will cause the friction pair of the hydraulic motor to wear quickly and shorten the life;
[0006] 3. Compared with mineral oil, it is difficult for the emulsion to form a protective film on the metal surface, which has a strong corrosion effect on the metal parts of the hydraulic motor and seriously affects the performance and life of the motor.

Embodiment Construction

[0025] Such as figure 1 , figure 2 As shown, the emulsion hydraulic motor of the present invention includes a non-circular gear train consisting of a heart wheel 9, a peripheral wheel 5 and 5 planetary gears. The wheel train, the front side plate 3, and the rear side plate 7 form a working chamber. On the side of the front side plate facing the working chamber, a compensating plate 8 that can move slightly in the axial direction is inlaid. On the side of the compensating plate facing away from the working cavity, an elastic compensating ring 11 is installed. The compensating plate The profile of 8 is consistent with the inner curve shape of the wheel and is slightly smaller; liquid inlet 1 and liquid outlet 2 are arranged on the rear side plate 7, and the front and rear side plates 3 and 7 are fastened and connected by screws 6. The heart wheel 9 is elliptical, with two perimeters and three perimeters. The elliptical heart wheel 9 and the triangular perimeter 5 are formed a...

Abstract

A liquor motor of noncircular wheel series is featured as applying operation cavity with automatic gap compensation function on motor, forming said cavity by one noncircular wheel series and front as well as back side plates, making noncircular wheel series have automatic hold function of side direction gap and making front side plate have automatic compensation function of axial gap, enabling to use liquor as operation media of said motor since micron grade function of seal movement gap can be constantly remained axially and radially by said operation cavity.

Description

technical field [0001] The invention belongs to the technical field of planetary gear hydraulic power actuators, and in particular relates to a non-circular gear system emulsion motor with emulsion as a working medium. Background technique [0002] Hydraulic motor is a widely used hydraulic actuator. Its structure is various. The common ones are plunger motor, vane motor, inner curve motor, etc., and mineral oil is usually used as the working medium. But it is not suitable to use mineral oil in every occasion. For example, in the underground of coal mines, the frequently used working medium is emulsion, so it is necessary to use a hydraulic motor with emulsion as the working medium. [0003] Conventional hydraulic motors have many problems when using emulsion as the working medium, such as low volumetric efficiency and short service life. This is mainly due to the nature of the emulsion different from mineral oil. details as follows: [0004] 1. Co...
