Description
Affiliated technical field
The utility model relates to the hydraulic transmission field, is a kind of cycloid hydraulic motor of built-in mechanical brake.
Background technique
At present, directly drive load with oil hydraulic motor, because the advantage of all many-sides, so recent two decades is applied rapidly in the whole world.When oil hydraulic motor is closed at oil inlet and outlet, output shaft is stopped operating fully.But, therefore, realize that braking is impossible fully because oil hydraulic motor exists the oil leakage phenomenon inevitably.Method commonly used is to install various breaks in load additional, or at the external mechanical brake of the output terminal of oil hydraulic motor.Install various breaks in the load additional because mechanism's complexity, handle inconvenience, volume is big.At present, more and more tend to, the oil hydraulic motor of band mechanical brake is provided with a whole set of form by the oil hydraulic motor MANUFACTURER at oil hydraulic motor output terminal additional mechanical break.Begun in recent years to use at the external break of the output terminal of cycloid hydraulic motor, but because the axial dimension of cycloid hydraulic motor own is big, axially size is bigger after the adjunction, has limited the application of band brake gerotor motor.
Summary of the invention
The purpose of this utility model is that a kind of cycloid hydraulic motor of built-in mechanical brake is provided to related domain.Solution is that mechanical brake brake axle is partly directly connected with the spline coupling of oil hydraulic motor, some movable friction plates are housed on brake axle, some friction plates of deciding are housed on the brake casing, with the elastic force of spring order about moving, decide friction plate and compress, produce braking action.When motor starting, hydraulic control oil enters from break control port, promotes piston with length of spring compressed, unclamp moving, decide friction plate, make revolution.Because mechanical brake directly is arranged in the output of cycloid hydraulic motor, thereby, simplified the structure, shortened axial dimension, made the application area that transmission is compacter, enlarged the band brake cycloid hydraulic motor.

Now in conjunction with the accompanying drawings, its feature is described as follows: the cycloid hydraulic motor of built-in mechanical brake, form the cycloid hydraulic motor part by rotor 11, rotor 9, spline coupling 10, roller 12, rear case 15, oil distribution mechanism etc., wherein oil distribution mechanism is made of auxiliary port plate 13, thrust plate 14, compensating disc 16 and short spline coupling 18; By brake axle 1, bearing 21, bearing 24, brake casing 7, decide friction plate 6, movable friction plate 5, piston seat 22, piston 4, spring 17, oil sealing 25, connecting plate 8, front cover 2 etc. and form the mechanical brake part; The spline coupling 10 that it is characterized in that oil hydraulic motor directly connects with the brake axle 1 of break, and the rotation of hydraulic motor rotor 11 and the output of moment of torsion are directly to reach brake axle 1 by spline coupling 10.Joining plate 8 is direct coupled with rotor 9, and another kind of connection form is that joining plate also can directly connect with front side plate 19.The movable friction plate 5 of mechanical brake parts and decide friction plate 6 and be located between piston 4 and the connecting plate 8 is loaded onto movable friction plate on brake axle, be equipped with on the brake casing 7 and decide friction plate, and their sheet number is that monolithic is to multi-disc.For setting up reducing gear, can on the position of front cover 2, set retarder 26.Embodiment
The cycloid hydraulic motor of built-in mechanical brake is on the position of common cycloid oil hydraulic motor output, and the design break is integrated the output and the break of cycloid hydraulic motor.The motion of hydraulic motor rotor and moment of torsion are directly passed to the brake axle 1 (output shaft of break) of break by spline coupling 10, some movable friction plates 5 are housed on the brake axle, some friction plates 6 of deciding are housed on the brake casing 7, when motor maybe need stop when not working because the elastic force of spring 3 (helical spring or butterfly spring), make movable friction plate and decide friction plate to compress, produce braking action.Hydraulic control oil is by " K during motor operations
2" mouthful enter, push piston 4 open, with length of spring compressed, unclamp movable friction plate and decide friction plate, motor running.Because braking component is directly designed in cycloid hydraulic motor, a plurality of parts such as front case, front cover, output shaft, bearing of former motor have been saved, make motor volume-diminished 1/3rd, entire belt break cycloid hydraulic motor can reach size, the volume and weight that former cycloid hydraulic motor is close, reduce transmission link, improved mechanical efficiency.
The control of break is adjunction one shuttle valve between oil inlet and outlet " A " at motor and " B ", the delivery outlet " K of shuttle valve
1" with " K of break
2" mouthful (see figure 2) that links to each other and realize.When any one hydraulic fluid port oil-feed of motor, shuttle valve can both provide pressure oil that break is opened.Otherwise, when motor is not worked or is stopped, " A " or " B " mouthful not oil-feed, break plays braking action owing to spring force compresses.Shuttle valve has been installed in motor, and with pipe with " K
1" and " K
2" connect." K when needing
2" mouth also can be connected with other control oil channel and adopt the external control form.The above-mentioned part of not describing all as relevant kit of the present utility model, does not describe in detail, and the spy illustrates in addition.
The cycloid hydraulic motor of built-in mechanical brake can connect with other mechanical device, sets up retarder as shown in Figure 3.Also can connect other load,, constitute compact mechanical transmission as the reel of winch etc.
