Description

Technical Field

[0001] The utility model relates to the technical field of motors, and in particular to a cycloid hydraulic motor applicable to multiple scenarios. Background Art

[0002] Cycloidal hydraulic motors are widely used, mainly in the rotary mechanisms of various machinery such as agriculture, fishery, light industry, lifting and transportation, mining, and engineering machinery. They have the characteristics of small size, light weight, wide speed range, and stepless speed regulation.

[0003] The installation of the cycloid hydraulic motor relies on the connecting flange on the motor housing. The existing motor housing has only one connecting flange, which has limited applicability. When customers require a different connection method, a new housing needs to be developed to match it, which is costly to use. In addition, under high power output and impact tooling, the single connection structure has poor stability, and the vibration generated can easily cause the connection to loosen and fail. Summary of the Invention

[0004] In order to solve the above technical problems, the utility model provides a cycloid hydraulic motor suitable for multiple scenarios, which can realize different connection methods, meet the needs of customers in different application conditions, and improve connection reliability.

[0005] The technical solution is as follows: a cycloidal hydraulic motor suitable for multiple scenarios, comprising a motor housing, characterized in that the motor housing is provided with two spaced-apart front connecting flanges and a rear connecting flange, the front connecting flange and the rear connecting flange are respectively provided with connecting holes, and a groove is provided on the outer surface of the motor housing between the front connecting flange and the rear connecting flange, and the position of the groove corresponds to the position of the connecting hole.

[0006] It is further characterized in that the rear connecting flange is formed by splicing a left half flange and a right half flange, and the left half flange and the right half flange are both mounted on the outer wall of the motor housing by fixing bolts;

[0007] The inner side surfaces of the left and right flange halves are provided with arc-shaped protrusions corresponding to the grooves, the inner walls of the left and right flange halves are provided with inner tooth areas, and the outer wall of the motor housing is provided with outer tooth areas cooperating with the inner tooth areas;

[0008] The left half flange, the right half flange, and the motor housing are all provided with matching fixing holes. The motor housing is provided with a plurality of fixing holes spaced apart in the axial direction, and the outer tooth area covers the area of ​​the fixing holes.

[0009] The upper end and the lower end of the left half flange and the right half flange are respectively provided with matched rod insertion slot mechanisms.

[0010] After adopting the utility model, a front flange and a rear flange are set on the motor housing, so that the front flange or the rear flange can be selected according to the actual situation during connection to avoid the obstacle area. When encountering high-power output, the front flange and the rear flange can be directly connected and used at the same time. The connection is reliable and the stability of the motor is improved. Different connection methods can be selected according to different working conditions to meet the different application working conditions of customers. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] See Figure 1 , Figure 5 , Figure 6 , Figure 7 As shown, a cycloid hydraulic motor suitable for multiple scenarios includes a motor housing 1, on which are provided two front connecting flanges 2 and rear connecting flanges 3 arranged at intervals. The front connecting flanges 2 and the rear connecting flanges 3 are respectively provided with connecting holes 4, which are used to connect to the base through bolts and nuts. A groove 5 is provided on the outer surface of the motor housing 1 between the front connecting flanges 2 and the rear connecting flanges 3. The position of the groove 5 corresponds to the position of the connecting hole 4, which is used to make room for the bolts and nuts.

[0019] The rear connecting flange 3 is spliced ​​by the left half flange 3-1 and the right half flange 3-2. The left half flange 3-1 and the right half flange 3-2 are both mounted on the outer wall of the motor housing 1 by fixing bolts. Since they are not integrally formed with the motor housing 1, in order to improve the connection stability and prevent deflection or axial movement after they are fixed, the inner side surfaces of the left half flange 3-1 and the right half flange 3-2 are provided with arc-shaped protrusions 3-3 corresponding to the grooves 5, and the inner walls of the left half flange 3-1 and the right half flange 3-2 are provided with inner tooth areas 3-4, and the outer wall of the motor housing 1 is provided with inner tooth areas 3-4. The outer tooth area 1-1, the arc-shaped protrusion 3-3 cooperates with the groove 5 to prevent it from rotating, and the inner tooth area 3-4 is stuck in the outer tooth area 1-1, which can effectively prevent the rear connecting flange 3 from moving back and forth; the left half flange 3-1, the right half flange 3-2, and the motor housing 1 are all provided with matching fixing holes 6, and the motor housing 1 is provided with multiple fixing holes 6 at intervals along the axial direction. The outer tooth area 1-1 covers the area of ​​the fixing holes 6. According to different usage conditions, the left half flange 3-1 and the right half flange 3-2 can be moved to different fixing hole 6 positions, and then the locking bolts 7 can be tightened.

[0020] The upper end and lower end of the left half flange 3-1 and the right half flange 3-2 are respectively provided with matching rod slot mechanisms 8, which can make the splicing of the two half flanges more stable and reliable.

[0021] Three different connection methods are given below.

[0022] like Figure 2 As shown, the front connecting flange 2 on the motor housing 1 is connected to the mounting base 10 via fixing bolts 9, and the rear connecting flange 3 is not connected.

[0023] like Figure 3 As shown, the rear connecting flange 3 on the motor housing 1 is connected to the mounting base 10 via fixing bolts 9, while the front connecting flange 2 is not connected.

[0024] The above two situations are mainly aimed at different installation environments to avoid obstacles and select a suitable installation location.

[0025] like Figure 4 As shown, the front connecting flange 2 and the rear connecting flange 3 on the motor housing 1 are connected to the two mounting bases 10 by fixing bolts 9. The rear mounting base is made into a split type to facilitate smooth connection. This method is particularly suitable for occasions where the motor has high power output, reducing the impact of vibration during motor operation and increasing the overall connection stability and service life of the motor.
