Abstract
The invention discloses the pistons for hydraulic motor, including sealing ring, it further include cylinder and pipe sleeve, the sealing snare is on the cylinder, the pipe sleeve covers on the cylinder, the both ends of the sealing ring are clamped and fixed between the cylinder and the pipe sleeve, and the first through hole communicated and the second through-hole are provided on cylinder described in the pipe sleeve box, and bolt passes through the first through hole and second through-hole.It is covered on cylinder in use, we can show sealing ring, then pipe sleeve is put on, be finally inserted bolt and fix, the installation of sealing ring can be significantly facilitated in this way.
Description
Technical field
The present invention relates to a kind of pistons for 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 the piston for hydraulic motor, can put convenient
Sealing ring is installed.
The present invention is achieved through the following technical solutions: further including column for the piston of hydraulic motor, including sealing ring
Body and pipe sleeve, on the cylinder, the pipe sleeve covers on the cylinder sealing snare, and the both ends of the sealing ring are pressed from both sides
It fastens between the cylinder and the pipe sleeve, is provided with the first through hole communicated and second on cylinder described in the pipe sleeve box
Through-hole, bolt pass through the first through hole and second through-hole.It is covered on cylinder in use, we can show sealing ring,
Pipe sleeve is put on again, bolt is finally inserted and fixes, the installation of sealing ring can be significantly facilitated in this way.
In above-mentioned technical proposal, it is preferred that the cylinder be include first part and second part, the first part
Diameter is greater than the second part, is provided with external screw thread on the second part, the pipe sleeve covers on the second part, institute
Sealing snare is stated on the second part, the sealing ring, which is clamped at, connects the first part and the second part
On step surface and between the end face of pipe sleeve.
In above-mentioned technical proposal, it is preferred that the diameter of the pipe sleeve outer ring is identical with the diameter of the first part outer ring.
The invention has the following beneficial effects: in use, we can show sealing ring covers on cylinder, then by pipe sleeve set
On, it is finally inserted bolt and fixes, the installation of sealing ring can be significantly facilitated in this way.
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:
It further include cylinder 2 and pipe sleeve 3 for the piston of hydraulic motor, including sealing ring 1, the cylinder 2 is packet referring to Fig. 1-2
Include first part 21 and second part 22, the diameter of the first part 21 is greater than the second part 22, and 3 sets of the pipe sleeve exists
On the second part 22,1 set of the sealing ring on the second part 22, the sealing ring 1 is clamped at described in connection
On the step surface of first part 21 and the second part 22 and between the end face of pipe sleeve 3.The diameter of 3 outer ring of pipe sleeve and
The diameter of 21 outer ring of first part is identical.The first through hole 31 communicated and are provided on cylinder 2 described in 3 box of pipe sleeve
Two through-hole 2a, bolt 4 pass through the first through hole 31 and the second through-hole 2a.
It is covered on cylinder in use, we can show sealing ring, then pipe sleeve is put on, sealing can be significantly facilitated in this way
The installation of circle.
