Description
Technical field
A kind of the present invention relates to novel hydraulic motor, more particularly, it relates to multiaction external curve radial plunger hydraulic pressure horse
Reach.
Background technology
Common hydraulic motor substantially has following lower several types currently on the market：1. gear motor, sliding-vane motor, cycloid
Motor, radial plunger piston motor, rotor hydraulic motor, screw rod hydraulic motor, multiple-action inner curved piston motor, axial piston motor
Etc..
The plunger of multiple-action inner curved piston motor is configured on the rotor of motor, and the center for occupying motor rotor is empty
Between, therefore the size of rotor will not be too little, general rotor limits motor applications scope without mesopore or intermediate pore size very little；In addition
The multiple-action inner curved of multiple-action inner curved motor is configured in casing (generally edge is fitted in casing), and inner curve processing is relative
More difficult, distribution oil ring (covering) is configured in motor center, occupies the space in motor center hole, in view of above-mentioned several situations, more
Effect inner curve piston motor rotor will not be too little.In other words, the motor in same size does not have larger through hole or without through hole.
The content of the invention
For the problems referred to above, multiaction external curve radial plunger type motor of the present invention configures plunger in stator (casing)
On, save rotor size, and external curve be configured in rotor it is cylindrical on, processing is simple, therefore multiaction external curve plunger horse
Up to larger through hole is capable of achieving, various functions part is can configure in big mesopore, the range of application of motor is expanded.
In order to achieve the above object, the present invention provides a kind of multiaction external curve radial plunger piston motor, including outline is in
Two faceplate types of curvilinear disk rotor, the stator for being placed on the rotor exterior and the rotor both sides that are placed in
Oil distribution casing, and some plungers for being spaced in rotate for rotor described in support top on the rotor outer circle week；Wherein, it is each described
Plunger both sides are respectively provided with a control valve rod and entry/exit oil hydraulic fluid port；The entry/exit oil hydraulic fluid port and the oil distribution casing, Yi Jisuo
The oil guide groove stated in stator constitutes the hydraulic-driven oil circuit for driving the plunger up and down reciprocatingly action；Additionally, the rotor center
It is connected to center output shaft；The control valve rod arranges control valve rod spring；The plunger arranges buffer spring.
Under optimal way, it is provided for supporting the bearing of the center output shaft rotation, Yi Jipei on the outside of the oil distribution casing
If end cap.The plunger is equipped with plunger capping.
Motor piston of the present invention is located in stator (casing), and rotor outer circle is multiaction external curve in many groove curves.
Radial plunger piston motor of the present invention has large through-hole, big flow, high-power slow-speed of revolution feature.Specifically：
1. large through-hole：The motor adopts multiaction outcurve line structure, the i.e. outer rim of rotor for multiaction outcurve line structure, post
Plug is not installed on internal rotor, but on stator (motor shell), thus greatlys save the sky at rotor center position
Between, increased the central hole size of motor, the increase of central hole size, it is convenient to configure all kinds of output shafts (such as splined shaft) defeated
Go out turning moment, hollow type female thread output sleeve, mix external screw thread leading screw, achievable leading screw is axially moveable, export straight line
Motion, big mesopore be also convenient for configure other various output mechanisms increased motor function.
2. output form is various：Motor can configure various export structure forms, such as hollow female thread axle sleeve, by hydraulic pressure horse
The rotary motion for reaching is converted to the linear motion of functional part；Hollow output shaft with keyway (or splined shaft) exports the rotation of motor
Transport dynamic etc..For overcoming axial load, it is furnished with taper roll bearing at output shaft two ends, makes motor both bear radial force, and
Axial force can be born.As multiaction plunger hydraulic motor is adapted to run under the high-power state of the slow-speed of revolution, subtract not configuring
Functional part can be directly driven to be operated in the case of fast mechanism, mechanism simplifying.
3. female thread export structure is adopted, one-level spiral reduction of speed itself is increased, reduction of speed can be produced very big than very big
Axial power output, directly drive the functional part of linear motion to be operated, realize that straight-line displacement is exported.
4. the slow-speed of revolution, huge discharge, high-power：The motor operations plunger quantity is more, and it is defeated that flow is more suitable for greatly low-speed big
Go out, many fluid cylinder alternations of the motor system, rotor each rotation will have k*m*n (the k rotor numbers of plies, m every layer of plunger number, n
The groove number of external curve rotor) individual plunger work, such as hydraulic motor described herein as, (per layer is to fix tentatively k=1 (monolayer), m=6
6 plungers), n=8 (rotor has 8 grooves), i.e. the motor rotor each rotation have the work of 1*6*8=48 plunger, therefore
Motor displacement is big, rotating speed is low, power big (theoretical power (horse-power) of motor is the product of flow and pressure), it is possible to achieve high-power, big
Flow, the slow-speed of revolution, big torque output.Motor can directly drive functional part and carry out work in the case where reducing gear is not configured
Make.Motor will be it can also be designed multilamellar plunger, its power, flow, output torque will be multiplied.
5. motor is capable of achieving multi-faceted, Suresh Kumar installation, quick and easy for installation：The motor can have multiple mounting modes, such as
Can be installed with being horizontally mounted of pedestal, reversely hung Yong, the multiple mounting modes such as the flange form of both sides is installed, it is quick and easy for installation, increase
Add the multiformity installed, can also be according to the various mounting means of the Demand Design of client.
