Abstract
The invention discloses the pistons of hydraulic motor, including sealing ring, it further include cylinder and two pipe sleeves, the sealing snare is on the cylinder, two pipe sleeves cover on the cylinder both ends, the both ends of the sealing ring are clamped and fixed between two pipe sleeves, are interference fit between described sleeve pipe and the cylinder, his outside of sleeve is provided with blind hole.When needing that sealing ring is installed, two ends of cylinder then can be knocked in from the both ends of cylinder respectively, the sealing ring is fixedly clamped between described sleeve pipe first by sealing snare on cylinder.This structure, sealing ring installation are very simple.
Description
Technical field
The present invention relates to a kind of pistons of hydraulic motor.
Background technique
Most important hydraulic motor is exactly to seal, and original sealing means are slotted on piston, then setting in slot again
The mode of sealing ring is realized, but this scheme, there are a defect, original sealing ring packs into very difficult in slot, installation
It is inconvenient, it is therefore necessary to be improved.
Summary of the invention
For the deficiencies in the prior art, the present invention provides a kind of piston of hydraulic motor, can put convenient
Sealing ring is installed.
The present invention is achieved through the following technical solutions: the piston of hydraulic motor, including sealing ring, further include cylinder and
Two pipe sleeves, the sealing snare is on the cylinder, and two pipe sleeves cover on the cylinder both ends, the sealing ring
Both ends are clamped and fixed between two pipe sleeves, are interference fit between described sleeve pipe and the cylinder, his casing
Outside is provided with blind hole.It, can be first by sealing snare on cylinder, then respectively from the both ends of cylinder when needing that sealing ring is installed
Two ends for knocking in cylinder, the sealing ring is fixedly clamped between described sleeve pipe.This structure, sealing ring are installed very
Simply.
In above-mentioned technical proposal, it is preferred that the cylinder is a cylindrical body, the end of described sleeve pipe and the cylinder
End flushes.
In above-mentioned technical proposal, it is preferred that the diameter of two pipe sleeve outer rings is identical.
It, can be first by sealing snare on cylinder, then when the invention has the following beneficial effects: needing to install sealing ring
Two ends for knocking in cylinder from the both ends of cylinder respectively, the sealing ring is fixedly clamped between described sleeve pipe.This knot
Structure, sealing ring installation are very simple.
Detailed description of the invention
Fig. 1 is schematic cross-sectional view of the invention.
Fig. 2 is structural schematic diagram of the invention.
Specific embodiment
Present invention is further described in detail with specific embodiment with reference to the accompanying drawing:
Referring to Fig. 1-2, a kind of piston of hydraulic motor, including sealing ring 1, it further include cylinder 2 and two pipe sleeves 3, described in two
The diameter of pipe sleeve outer ring is identical.
1 set of the sealing ring on the cylinder 2, two 3 sets of the pipe sleeve on 2 both ends of cylinder, the sealing
The both ends of circle 1 are clamped and fixed between two pipe sleeves 3, are interference fit, institute between described sleeve pipe 3 and the cylinder 1
It states and is provided with blind hole 31 on the outside of his casing 3.The cylinder is a cylindrical body, the end of the end of described sleeve pipe and the cylinder
It flushes.
When needing that sealing ring is installed, column then can be knocked in from the both ends of cylinder respectively first by sealing snare on cylinder
Two ends of body, the sealing ring is fixedly clamped between described sleeve pipe.This structure, sealing ring installation are very simple.
