Abstract
The utility model discloses a driving unit of hydraulic motor which comprises hydraulic motor, brake, cycloid pin wheel reducer, characterized in that: one end of brake outer casing is connected with output end on outer casing of hydraulic motor, the other end is connected with input end on outer casing of cycloid pin wheel reducer, the output shaft of hydraulic motor is connected with the input shaft of cycloid pin wheel reducer; the brake is suited on input shaft of cycloid pin wheel reducer and output shaft of hydraulic motor. The utility model of hydraulic motor driving unit adopt cycloid pin wheel reducer, which has the advantage of satisfying the requirements of industrial production for more bearing capacity, stronger overload capacity and higher transmission efficiency of driving unit of hydraulic motor.
Description
(1) technical field
The utility model belongs to hydraulic power unit, a kind of specifically driving device for hydraulic motor.
(2) background technique
The speed reducer of traditional driving device for hydraulic motor adopts planet-gear speed reducer, along with industrial expansion, bearing capacity, anti-overload ability and total transmission efficiency to driving device for hydraulic motor, have higher requirement, adopt the driving device for hydraulic motor of planet-gear speed reducer to be difficult to satisfy industrial production requirement in these areas.
(3) summary of the invention
The purpose of this utility model is to provide the driving device for hydraulic motor that a kind of bearing capacity is bigger, anti-overload ability is stronger, total transmission efficiency is higher at above-mentioned technical problem.
The purpose of this utility model is realized by following technological scheme: a kind of driving device for hydraulic motor, comprise oil hydraulic motor 3, break 2, cycloidal planetary gear speed reducer 1, it is characterized in that an end of the shell 22 of break 2 connects the shell of oil hydraulic motor 3 output terminals, the other end connects the shell of the input end of cycloidal planetary gear speed reducer 1, and the output shaft of oil hydraulic motor 3 connects the input shaft of cycloidal planetary gear speed reducer 1; Break 2 is sleeved on the output shaft of the input shaft of cycloidal planetary gear speed reducer 1 and oil hydraulic motor 3.
The output shaft of oil hydraulic motor 3 and cycloidal planetary gear speed reducer 1 input shaft suit are connected by key; Perhaps the output shaft of oil hydraulic motor 3 adopts splined shaft to be connected with the mode of splined hole with the input shaft of cycloidal planetary gear speed reducer 1; Also can be that the input shaft of cycloidal planetary gear speed reducer 1 and the output shaft of oil hydraulic motor 3 are connected by spline housing.
The brake stator sheet 24 of break 2 is installed in the splined hole of shell 22, the moving braking plate 23 of break 2 is sleeved on the external splines of the output shaft of oil hydraulic motor 3 and cycloidal planetary gear speed reducer 1 input shaft, perhaps is installed on the external splines of spline housing of output shaft of the input shaft that connects cycloidal planetary gear speed reducer 1 and oil hydraulic motor 3.
When oil hydraulic motor 3 rotates, high pressure oil promotes brake piston 25 compression brake springs 27, moving braking plate 23 and brake stator sheet 24 disengage, removed the braking of the input shaft of cycloidal planetary gear speed reducer 1, the input shaft that the output shaft of oil hydraulic motor 3 has driven the cycloidal planetary gear speed reducer 1 that is attached thereto rotates, by cycloidal planetary gear speed reducer 1 slow down increase square after, power is from the output shaft output of cycloidal planetary gear speed reducer 1; When oil hydraulic motor 3 stalls, high pressure oil becomes low pressure oil, and under brake spring 27 effects, brake piston 25 compresses moving braking plate 23 and brake stator sheet 24, and the input shaft of cycloidal planetary gear speed reducer 1 is braked.
The utility model has the advantages that: cycloidal planetary gear speed reducer has that bearing capacity is big, anti-overload ability is strong, total high advantage of transmission efficiency, driving device for hydraulic motor of the present utility model adopts cycloidal planetary gear speed reducer, has satisfied the requirement that bearing capacity bigger, anti-overload ability stronger, total transmission efficiency higher of industrial production to driving device for hydraulic motor.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model;
(5) embodiment
A kind of mode of execution of the present utility model shown in Figure 1, an end connecting flange 26 of the shell 22 of break 2 is connected by bolt 5 with the shell of oil hydraulic motor 3 output terminals, and the other end connects the shell of the input end of cycloidal planetary gear speed reducer 1 by bolt 4.The output shaft of oil hydraulic motor 3 is inserted in the input shaft axis hole of cycloidal planetary gear speed reducer 1, connects by flat key.The brake stator sheet 24 of break 2 is installed in the splined hole of shell 22, and the moving braking plate 23 of break 2 is sleeved on the external splines of cycloidal planetary gear speed reducer 1 input shaft.The two ends of brake spring 27 contact the endoporus of connecting flange 26 and brake piston 25 respectively, and the left end of break 2 is braking plate glands 21, and the high pressure oil that promotion brake piston 25 moves is opened hydraulic fluid port 28 inputs by braking.
