Abstract
The utility model provides a hydraulic clutch so as to solve the problems that a hydraulic clutch in the prior art is prone to abrasion and short in service life after running for long. The hydraulic clutch comprises a body, wherein friction plates are arranged inside the body, a bearing sleeve is arranged on the left sides of the friction plates, a plunger body is arranged in the body and located on the left side of the bearing sleeve, nine plunger holes which are blind holes are uniformly formed in the periphery of the plunger body, plungers are arranged in the plunger holes, and the plunger body is provided with an oil inlet hole and further provided with three oil sealing grooves. According to the hydraulic clutch, the plunger body is additionally arranged on an original hydraulic clutch, the design is ingenious, friction resistance of the hydraulic clutch is reduced effectively, the hydraulic clutch is long in service life after running for long, the cost of spare parts is reduced, and the cost for equipment replacement is also reduced; moreover, the hydraulic clutch is simple in structure and easy and convenient to operate.
Description
Technical field
the utility model belongs to mechanical field, particularly a kind of hydraulic coupling.
Background technique
The wearing and tearing that hydraulic coupling relies on stroke energy auto-compensation friction element, easily realize seriation, standardization, therefore be widely used in claimed structure compactness, engage frequently, on high speed and remote-controlled lathe, engineering machinery and boats and ships.Hydraulic coupling is due to long-time running, and internal friction makes easy to wearly, and long-time running meeting causes hydraulic coupling serious wear, makes working life short.
Model utility content
The purpose of this utility model is to provide a kind of hydraulic coupling, to solve the long-time running existing in prior art, has problem easy to wear, working life is short.
For achieving the above object, the utility model is by the following technical solutions:
A kind of hydraulic coupling, comprise body, in described body, be provided with friction plate, described friction plate one side is provided with bearing housing, in described body, is provided with plunger body, described plunger body is positioned at described bearing housing one side, described plunger body even circumferential is arranged 9 plunger holes, and described plunger hole is blind hole, in described plunger hole, is provided with plunger, described plunger body is provided with oil inlet hole, is also provided with 3 oil sealing grooves on described plunger body.
The facing-up gap of plunger hole and plunger is 0.006～0.015 μ m.
The internal diameter of plunger hole is 20mm, and the degree of depth is 21mm, and the external diameter of described plunger is 20mm, and length is 20mm.
The utility model has increased plunger body in original hydraulic coupling, designs ingeniously, has effectively reduced the friction resistance of hydraulic coupling, long-time running long service life, has saved spare parts cost, has reduced because the cost that more exchange device produces, and simple in structure, easy and simple to handle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of plunger body of the present utility model;
Fig. 3 is the side view of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, 2, 3, the utility model hydraulic coupling comprises body 1, in body 1, be provided with friction plate 2, friction plate 2 one sides are provided with bearing housing 4, are provided with plunger body 3 in body 1, plunger body 3 is positioned at bearing housing 4 one sides, plunger body 3 even circumferentials are arranged 9 plunger holes 5, and plunger hole 5 is blind hole, is provided with plunger 8 in plunger hole 5, plunger body 3 is provided with oil inlet hole 6, is also provided with 3 oil sealing grooves 7 on described plunger body 3.
Because processing is not through hole processing, so matching gap is difficult to guarantee.Plunger hole 5 is 0.006～0.015 μ m with the facing-up gap of plunger 8.
For guaranteeing that hydraulic oil does not leak, the internal diameter of plunger hole 5 is 20mm, and the degree of depth is 21mm, and the external diameter of plunger 8 is 20mm, and length is 20mm.
By hydraulic system, according to requirements control and pass into pressure oil, promote plunger motion, make friction plate adhesive drive output shaft motion.Hydraulic oil promotes plunger motion, the interior outside friction disc combination of hydraulic coupling; Oil hydraulic circuit commutation, the spring reset of hydraulic coupling, inside and outside wearing piece is separated.
The utility model, by increased plunger body in original hydraulic coupling, has effectively reduced the friction resistance of hydraulic coupling, and long-time running long service life, has reduced because the cost that more exchange device produces.
