Abstract
The invention discloses a kind of material combined forcep hydraulic motor, including hydraulic cylinder, drive end bearing bracket, rear end cap, it is characterized by and is provided with hydraulic cylinder on hydraulic cylinder external diameter, hydraulic cylinder and hydraulic cylinder phase fixed；Rear end cap is provided with and the material of drive end bearing bracket difference.Use bi-material can alleviate motor weight.Compared with prior art, its advantage and providing the benefit that: the present invention uses hydraulic cylinder Split type structure, motor uses material combined forcep structure, in the case of ensureing that hydraulic motor displacement is constant, the weight of hydraulic motor significantly alleviates, and efficiently reduces the volume of hydraulic motor.
Description
Technical field
The present invention relates to the main part of hydraulic motor technology, specifically hydraulic motor and use material
Combined mode is fabricated by.
Background technology
Hydraulic motor is the driver part of a kind of high pulling torque, often uses in space industry, example
As in space flight turntable test equipment.Hydraulic motor is widely used as driver part, its
Comparing with torque motor, under equal volume, hydraulic motor possesses bigger output moment of torsion；Meanwhile,
The control mode of hydraulic motor determines that the Influence from Eccentric that its position control is loaded is less.In load
In the case of having bias or needing the biggest angular acceleration, use hydraulic motor the most suitable.
Although hydraulic motor can export the biggest moment of torsion under small size, but due to its zero
Part material is usually steel, there is the problem that weight lays particular stress on.Especially want in space industry
Ask that hydraulic motor is lightweight, volume is little.As used multistage steel hydraulic motor to turn round, its prime
Hydraulic motor is really the load of rear class, therefore in the system of multi-stage rotary, controls hydraulic pressure horse
The weight and volume reached is very important.
Summary of the invention
The technical problem to be solved in the present invention is to provide the hydraulic motor of a kind of material combined forcep, energy
Effectively reduce the weight of hydraulic motor.
For solving above-mentioned technical problem, the present invention is to be realized by following technical scheme, one
Planting material combined forcep hydraulic motor, including hydraulic cylinder, drive end bearing bracket, rear end cap, its structure is wanted
Point is to be provided with hydraulic cylinder on hydraulic cylinder external diameter, hydraulic cylinder and hydraulic cylinder phase fixed；
Rear end cap is provided with and the material of drive end bearing bracket difference.Use bi-material can alleviate motor weight.
The material of described hydraulic cylinder is steel, and the material of hydraulic cylinder is aluminium alloy, hydraulic cylinder
Body is matched by interference with hydraulic cylinder.
The material of described drive end bearing bracket is steel, it is simple to threaded, and the material of rear end cap is that aluminum closes
Gold, to alleviate motor weight.
The present invention uses hydraulic cylinder Split type structure, and motor uses material combined forcep structure, with existing
Technology is compared, its advantage and providing the benefit that:
In the case of ensureing that hydraulic motor displacement is constant, the weight of hydraulic motor significantly alleviates,
And effectively reduce the volume of hydraulic motor.
Accompanying drawing explanation
Below with reference to drawings and Examples, the present invention is further illustrated.
Fig. 1 is the structural representation of hydraulic motor of the present invention.
In figure:
Rear flange 1, rear end cap 2, hydraulic cylinder 3, hydraulic cylinder 4, drive end bearing bracket 5, forward flange
6, main shaft 7.
Detailed description of the invention
As it is shown in figure 1, be the structural representation of the present invention, hydraulic motor include rear flange 1,
Rear end cap 2, hydraulic cylinder 3, hydraulic cylinder 4, drive end bearing bracket 5, forward flange 6, main shaft 7.Main
Equipped with hydraulic cylinder 4 on axle 7, the two ends of hydraulic cylinder 4 are respectively provided with drive end bearing bracket 5, rear end cap 2,
The other end at drive end bearing bracket 5, rear end cap 2 is respectively provided with forward flange 6, rear flange 1.For subtracting
The weight of light liquid cylinder pressure 4, hydraulic cylinder 4 uses inside and outside Split type structure, i.e. hydraulic cylinder 3 to overlap
Being loaded on hydraulic cylinder 4 external diameter, hydraulic cylinder 3 uses aluminum alloy materials, hydraulic cylinder 4 to use steel
Material, hydraulic cylinder 3 uses interference fit to be nested with hydraulic cylinder 4, and its magnitude of interference is
0.02～0.03mm, so can effectively inhibit hydraulic cylinder 4 deformation under high pressure, simultaneously
Reach to alleviate the weight of hydraulic motor.
Using difference to use the material of drive end bearing bracket 5 and rear end cap 2, the material of drive end bearing bracket 5 is steel
Material, the model of this example steel is 38CrMoL, hydraulic motor can be made externally to be screwed with steel,
It is easy to screw and coordinates the processing of port, and can ensure that installation reliability with threaded, with
Time suitably reduce volume；The material of rear end cap 2 is aluminium alloy, and carries out at surface hard anode
Reason, uses aluminium alloy rear end cap 2 to alleviate motor weight.
Obviously, those skilled in the art the present invention can be carried out various change and deformation and not
Depart from the spirit and scope of the present invention.So, if these amendments and deformation belong to present invention power
Profit requires and within the scope of equivalent technologies, then the present invention is also intended to comprise these changes and become
Including shape.
