Description

Technical Field

[0001] This utility model relates to the field of power device technology, specifically a multi-functional hydraulic cycloidal motor. Background Technology

[0002] Hydraulic cycloidal motors require hydraulic valve assemblies for control during operation. Existing hydraulic cycloidal motor layouts require additional space for hydraulic brakes and hydraulic valve assemblies, along with multiple oil lines, resulting in large space requirements and high operating costs. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model provides a multi-functional hydraulic cycloidal motor, which has a compact structure, occupies little space, and has low operating costs.

[0004] The technical solution is as follows: a multifunctional hydraulic cycloidal motor, comprising a motor body, a hydraulic brake, and a hydraulic valve assembly, characterized in that the motor body and the hydraulic brake are an integral structure, the output shaft of the motor body passes through the hydraulic brake and an output gear is installed at the end, the hydraulic valve assembly is fixed on the motor body, the oil port on the motor body is directly connected to the oil port of the hydraulic valve assembly, the hydraulic valve assembly is also connected to the hydraulic brake through an oil pipe, and the hydraulic valve assembly has two working oil ports.

[0005] A further feature is that the hydraulic valve assembly is fixedly connected to the motor body by bolts;

[0006] The hydraulic valve group is equipped with a two-way relief valve and a shuttle valve.

[0007] The output gear is engaged with the output shaft of the motor body via a keyway and a flat key, and is fixed by a snap ring.

[0008] One end of the output gear abuts against the boss of the output shaft of the motor body, and the other end is flush with the end face of the output shaft.

[0009] By adopting this utility model, the hydraulic brake, hydraulic motor and hydraulic valve group are integrated into one unit. The hydraulic valve group controls the operation of the hydraulic motor and the hydraulic brake at the same time. The structure is compact, eliminating the complicated oil circuit. Only one oil pipe is needed to connect the hydraulic valve group and the hydraulic brake. The installation and maintenance are convenient, the space occupied is small and the operating cost is low.

[0013] Figure 4 This is a schematic diagram of the output gear installation. Detailed Implementation

[0014] See Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a multifunctional hydraulic cycloidal motor includes a motor body 1, a hydraulic brake 2, and a hydraulic valve group 3. The motor body 1 and the hydraulic brake 2 are an integral structure. The output shaft 4 of the motor body 1 passes through the hydraulic brake 2 and an output gear 5 is installed at the end. The hydraulic valve group 3 is fixed on the motor body 1 and is fixedly connected to the motor body 1 by bolts 6.

[0015] The oil port on the motor body 1 is directly connected to the oil port of the hydraulic valve group 3 without the need for an intermediate oil pipe connection. The hydraulic valve group 3 is also connected to the hydraulic brake 2 through the oil pipe 7. The hydraulic valve group 3 has two working oil ports, namely oil port A and oil port B, and also has an oil discharge port, namely oil port T. The oil port T can be opened or blocked with a plug according to customer needs. When opened, the oil inside the motor can be discharged.

[0016] The hydraulic valve assembly 3 is equipped with a two-way relief valve and a shuttle valve. The shuttle valve is used to control the operation of the hydraulic brake, and the two-way relief valve can prevent motor overload.

[0017] When the hydraulic motor is working, the shuttle valve in the hydraulic valve group 3 supplies hydraulic oil to the hydraulic brake 2, and the hydraulic brake 2 releases the braking force under the pressure of the hydraulic oil.

[0018] When the hydraulic motor stops working, the hydraulic brake 2 brakes and locks the hydraulic motor.

[0019] When the hydraulic motor is overloaded, the bidirectional relief valve in the hydraulic valve group 3 overflows, the motor stops working, and the hydraulic brake 2 also brakes and locks the hydraulic motor.

[0020] Integrating the hydraulic motor, hydraulic valve assembly, and hydraulic brake into one unit greatly saves space in the hydraulic system and reduces costs. At the same time, the hydraulic motor, hydraulic valve assembly, and hydraulic brake can respond and work together quickly.

[0021] The output gear 5 is engaged with the output shaft 4 of the motor body 1 via a keyway and a flat key 8, and is fixed by a retaining spring 9 to limit axial displacement. One end of the output gear 5 abuts against the boss of the output shaft 4 of the motor body 1, and the other end is flush with the end face of the output shaft 4. The output gear 5 and the output shaft 4 are designed separately, which is convenient for installation. The output gear and the output shaft do not need to be machined as a whole, which reduces the complexity of component processing and further saves the manufacturing cost of motor components. In addition, with this design, the motor output shaft can be kept unchanged, and only the design of the output gear is changed, which effectively saves the complexity of motor assembly and motor cost. It can facilitate the quick change and maintenance of the output gear, while reducing maintenance costs.
