Problems solved by technology

However, for applications with more shaft extensions and radial forces, such as the working conditions of driving external meshing gears or large loads driven by sprockets, etc., the prior art small-scale shaft distribution cycloid hydraulic motor structure is used in the application There are some deficiencies in reliability and other aspects, and the requirements for the working conditions of the application are high. For example, the cleaning motor of the rapidly developing sweeper, due to the harsh working conditions, the failure rate of motors from different suppliers at home and abroad has reached more than 2% in the life cycle. , it is necessary to further improve the precision of its own connecting parts and the anti-harsh industrial and mining ability of the motor, so as to improve the service life

Embodiment 1

[0022] The basic composition of a large radial force supporting shaft distribution cycloidal hydraulic motor in this embodiment can be found in figure 1 As shown, combined with the above figure 1 Examples, the present invention is described in detail as follows. A large radial force supporting shaft distribution cycloidal hydraulic motor in this embodiment has an SAE A-type standard Φ82.55 installation notch or a close-to-size installation notch, and a body shell 8 with a mounting flange surface, which is placed on the body shell The output shaft 1 structure of the torque output in 8, and the rotor stator pair fixedly connected with the body shell 8 by connecting bolts 23, the flow distribution system and the flow channel for the oil to enter and exit the motor cavity and the rear cover 19, through the high and low pressure oil The liquid enters and exits the flow path of the inner cavity of the motor to the stator pair 18 to generate torque, which is transmitted to the outpu...

Embodiment 2

[0030] This embodiment uses Figure 5 In the first embodiment of structure replacement figure 1 The structure of the front cover 5, Figure 5 It is an installation surface intention of front cover 5' in embodiment two, and Image 6 for Figure 5From the schematic diagram of the front cover 5', it can be seen that the front cover 5' is nested in the circular surface of the positioning spigot of the body shell 9. A front cover 5' is provided, said front cover 5' being provided with a rotary shaft seal 4. The cylindrical head installation hole of the screw 7 of the front cover 5' is a milled semicircular opening structure, the cylindrical head of the screw 7 is completely installed on the front cover 5', and the ingenious design of the front cover 5' ensures the reliable installation of the motor positioning notch .

Abstract

The invention relates to a large-radial-force supporting shaft flow distribution cycloid hydraulic motor, and belongs to the technical field of hydraulic transmission. The front end of a motor output shaft is provided with a front prop which refers to a full complement cylindrical roller bearing. The outer circle of the front prop and the outer circle of a rear prop are mounted onto the through hole round face of a body shell. A step of the output shaft abuts against a cylindrical roller of the front bearing prop and further conducts axial limitation. A gap is kept between a supporting frame of the front bearing prop and the axial direction of the output shaft. The supporting frame of the cylindrical roller bearing abuts against a check ring, and the other end of the check ring abuts against a front cover. By the adoption of the large-radial-force supporting shaft flow distribution cycloid hydraulic motor, the structure of the motor is made simpler and more reliable, radial and axial force bearing capacity of motor shaft extension is higher, the fabrication property is good, and the problems of rigidity, reliability and the like of a main force-carrying bearing are well solved.

Description

technical field [0001] The invention relates to a cycloidal hydraulic motor which converts hydraulic energy into mechanical energy through the meshing pair of a cycloidal pinwheel group, in particular to a cycloidal hydraulic motor with large radial force supporting shaft distribution and belongs to the technical field of hydraulic transmission. Background technique [0002] The cycloidal hydraulic motor is a commonly used hydraulic drive device. It is a low-speed and high-torque motor. It has the advantages of small size, high unit power density, high efficiency, and wide speed range. It has been widely used. will be more extensive. [0003] The basic structure of this type of device is that the body shell or the back cover is formed with a liquid inlet and a return port, and one end is equipped with a cycloidal pinwheel meshing pair and a flow distribution mechanism. The flow distribution mechanism can be placed before or after the cycloidal pinwheel meshing pair. General...
