Abstract
The utility model discloses a concealed two-speed axial piston motor comprising a hydraulic motor, a planetary gear reducer and a stopping braking device. The utility model has the advantages of compact structure, easy installation and convenient maintenance.
Description
Technical field:
The utility model relates to a kind of piston motor.
Background technique:
The design stop device is connected with plane table thermoconductivity meter in the existing double speed axial piston motor, oil hydraulic motor, the back maintenance difficult that breaks down, and particularly in the track-type engineering machinery, the sideslip error that requires two motors to drive is difficult to reach.
Summary of the invention:
The purpose of this utility model is to provide a kind of compact structure, exchanges the good built-in double speed hydraulic motor of performance.
Technical solution of the present utility model is:
A kind of built-in double speed axial piston motor has comprised oil hydraulic motor, plane table thermoconductivity meter, stop device, and it is characterized in that: motor directly inserts retarder.
The mounting flange design of double speed axial piston motor is in the centre of housing, and this structure allows motor almost completely to put in the retarder, only remaining valve body and the mounting flange that needs to connect hydraulic fluid port, thus very compact parts are provided.In the track-type engineering machinery, the sideslip error requirements that two motors are driven is than higher, this just requires drift angle before and after two motor speed varyings, efficient very approaching, present this structure has solved this difficult problem well, as long as two motor displacements, efficient are basic identical, be connected the back rotating speed with plane table thermoconductivity meter equal substantially, just can meet the sideslip error requirements.Because only need insert retarder, install very convenient simultaneously.If because sideslip occurring needs repairing, as long as change a motor, the exchange performance is good, does not need integral body to take apart, influences precision, concerning the user, when both connect, does not need to consider location tolerance.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is an embodiment's of the utility model a configuration diagram.
Embodiment:
A kind of built-in double speed axial piston motor, oil hydraulic motor 1 is as parts independently, major part is all hidden in the retarder 3, only stay a control port to stop device 2 on the housing, hydraulic part is separated fully with mechanical part, under the normal condition, motor 1 tick-over, open outer governor pressure, motor 1 high speed operation.Stop device 2 is installed on the plane table thermoconductivity meter 3, and when not needing work, the brake block in the braking device 2 is compressed under the effect of spring force mutually, retarder 3 is braked, and when needing work, control oil promotes piston, brake block unclamps, and braking is removed, just can proper functioning.
Claims (2)
