Technical Field
[0001] The present application relates to the technical field of mechanical hydraulic devices, and particularly to a hydraulic motor housing with a flange plate. Background Art
[0002] A speed reducer is a common rotational output device, which mainly includes a prime mover and a speed reduction transmission component. Common prime movers are mainly motors or hydraulic motors, and the speed reduction transmission component is generally a planetary speed reducer. The output shaft of the prime mover is connected to the planetary speed reducer, and the speed regulation and torque transmission are achieved through the meshing transmission relationship of the gear set. Among them, compared with motors, hydraulic motors have the advantages of high torque, low speed, and high transmission torque, and are commonly used in environments with large torque output.
[0003] In the related art, when connecting a hydraulic motor to a planetary speed reducer, generally several screws are passed through the housing of the hydraulic motor, and the screws are threadedly connected to the outer shell of the planetary speed reducer. The output shaft of the hydraulic motor meshes with the driven gear of the planetary speed reducer, thereby driving the gear set in the planetary speed reducer to rotate, so as to achieve the adjustment of the output speed and output torque.
[0004] In view of the above related art, the inventor found the following defects: The positions of the holes for the screws to pass through on the hydraulic motor housing and the planetary speed reducer are fixed, resulting in that the hydraulic motor and the planetary speed reducer must correspond one by one, that is, the hydraulic motor cannot be adapted to planetary speed reducers of different model sizes.

Thus, it is convenient for the installation and fixation of the first screw.
[0011] Optionally, a positioning protrusion is provided on the housing body, and a positioning groove for the positioning protrusion to be inserted into is provided on the flange.

[0017] Optionally, a guiding inclined wall is provided on the inner side wall of the fixing perimeter, the guiding inclined wall is annular, and the inner diameter of the guiding inclined wall gradually decreases from the side away from the flange to the other side.

[0019] Optionally, an elastic component is provided on the inner wall of the fixing perimeter, and the elastic component is used to abut against the upper end surface of the planetary reducer.
[0020] By adopting the above technical solution, by providing the elastic component, the sinking of the hydraulic motor is buffered, so that during the installation of the hydraulic motor, the impact force on the upper end surface of the planetary reducer due to gravity factors is reduced.

Specific embodiments
[0035] The following will Figures 1-5 further elaborate on the present application in detail with reference to the attached drawings.
[0036] The embodiment of the present application discloses a hydraulic motor housing with a flange 2.
[0037] Refer to Figure 1 and Figure 2 , the hydraulic motor housing is used to be connected to the planetary reducer 3 to achieve the adjustment of the output speed and output torque of the hydraulic motor. Among them, the hydraulic motor has an output shaft 4 for outputting rotational torque, and external teeth are provided on the output shaft 4; the planetary reducer 3 has a driven wheel 32 that meshes and drives with the output shaft 4, and the driven wheel 32 has internal teeth 33 that mesh and drive with the output shaft 4.
[0038] Refer to Figure 1 and Figure 2 , the hydraulic motor housing with a flange 2 includes a housing body 1 and a flange 2 provided on the housing body 1. A first screw 11 that is threaded with the flange 2 is passed through the housing body 1 to achieve the detachable connection between the housing body 1 and the flange 2, and a plurality of second screws 21 for threading with the planetary reducer 3 are passed through the flange 2 to achieve the detachable connection between the flange 2 and the planetary reducer 3. When the hydraulic motor needs to be connected to planetary reducers 3 of different sizes, only the flange 2 with different radius sizes needs to be replaced. It should be noted that when replacing different planetary reducers 3, it is necessary to ensure that the model of the driven wheel 32 on the planetary reducer 3 remains unchanged, that is, the inner diameter and the number of teeth of the internal teeth 33 remain unchanged, so as to ensure that the driven wheel 32 can mesh and drive with the output shaft 4 of the hydraulic motor.
[0039] Refer to Figure 2, a plurality of first threaded holes 12 are formed in the housing body 1, and a plurality of second threaded holes 22 corresponding to the first threaded holes 12 are formed in the flange 2. The first screw 11 is inserted into the first threaded hole 12 and the second threaded hole 22, thereby connecting the housing body 1 and the flange 2. In this embodiment, five first screws 11 are circumferentially arranged at equal intervals. Among them, the first threaded hole can be a threaded hole or a hole without threads. In this embodiment, the first threaded hole is not provided with threads.
[0040] Referring to Figure 2 and Figure 3 , a first through hole 13 for the output shaft 4 to pass through is formed in the housing body 1, and a second through hole 23 for the output shaft 4 to pass through is formed in the flange 2. Among them, the inner diameter of the second through hole 23 is larger than the outer diameter of the output shaft 4. A positioning convex ring 14 is integrally provided on the housing body 1. The positioning convex ring 14 is inserted into the second through hole 23 and abuts against the hole wall of the second through hole 23, thereby axially limiting the flange 2, facilitating the subsequent alignment of the first threaded hole 12 and the second threaded hole 22, and facilitating the insertion of the first screw 11.
[0041] Referring to Figure 2 and Figure 3 , a positioning protrusion 15 is also integrally welded and fixed on the housing body 1, and a positioning groove 24 for the positioning protrusion 15 to be embedded is formed in the flange 2. In this embodiment, both the positioning protrusion 15 and the positioning groove 24 are provided with two. After the positioning convex ring 14 is inserted into the second through hole 23, the housing body 1 is rotated until the positioning protrusion 15 is rotated into the positioning groove 24. At this time, the first threaded hole 12 and the second threaded hole 22 are aligned, and the first screw 11 can be directly inserted and installed. During this process, in order to facilitate the rotation of the housing body 1, the positioning protrusion 15 is provided with a hemispherical shape. Correspondingly, the positioning groove 24 is also hemispherical.
[0042] Referring to Figure 2 , a plurality of third threaded holes 25 are formed in the flange 2, and a plurality of fourth threaded holes 31 corresponding to the third threaded holes 25 are formed in the planetary reducer 3. By inserting the second screw 21 into the third threaded hole 25 and the fourth threaded hole 31, the connection between the flange 2 and the planetary reducer 3 is realized.
[0043] Referring to Figure 4 , a fixing perimeter 26 is integrally provided on the side of the flange 2 away from the housing body 1. The fixing perimeter 26 is used to sleeve the outside of the planetary reducer 3. The inner side of the end of the fixing perimeter 26 has a guiding inclined wall 27. The guiding inclined wall 27 is annular, and the inner diameter of the guiding inclined wall 27 gradually decreases from the side away from the flange 2 to the other side. By providing the guiding inclined wall 27, it is convenient to cover the flange 2 on the planetary reducer 3.
[0044] Referring toFigure 4 With Figure 5 , an elastic component 28 is provided on the inner side wall of the fixed border 26, and the elastic component 28 is used to abut against the upper end surface of the planetary reducer 3. After the flange 2 is fixed to the housing body 1 by the first screw 11, the flange 2 is covered on the planetary reducer 3, and the elastic component 28 abuts against the upper end surface of the planetary reducer 3. At this time, since the teeth on the output shaft 4 cannot be directly inserted into the tooth grooves of the internal teeth 33 of the driven wheel 32 just right, the flange 2 needs to be slightly rotated. When the teeth on the output shaft 4 just rotate to align with the tooth grooves of the internal teeth 33 of the driven gear, under the action of gravity, the flange 2 and the hydraulic motor sink, and the teeth on the output shaft 4 slide and embed into the tooth grooves of the internal teeth 33 of the driven wheel 32. At the same time, under the buffering action of the elastic component 28, the sinking of the flange 2 is buffered, reducing the impact force of the entire hydraulic motor directly hitting the upper end surface of the planetary reducer 3.
[0045] The elastic component 28 includes a buffer spring 281 and a ball 282 for abutting against the upper end surface of the planetary reducer 3. In this embodiment, both the buffer spring 281 and the ball 282 are provided in multiple numbers and correspond one by one. The multiple buffer springs 281 are circumferentially and equidistantly distributed on the inner side wall of the fixed border 26. By providing the ball 282, the rotation of the flange 2 is made smoother.
[0046] The elastic component 28 further includes a connecting ring 283. One end of the buffer spring 281 is fixedly welded to the connecting ring 283, and the other end is fixedly welded to the ball 282. The connecting ring 283 can be fixed to the end of the flange 2 by welding or bonding. A clearance hole 284 for the second screw 21 to pass through is provided on the connecting ring 283. After the output shaft 4 of the hydraulic motor meshes with the driven gear of the planetary reducer 3, the flange 2 needs to be rotated so that the third threaded hole 25 and the fourth threaded hole 31 can be aligned, facilitating the insertion of the second screw 21. During the rotation of the flange 2, the output shaft 4 and the driven wheel 32 rotate synchronously. At this time, the buffer spring 281 generates an upward elastic force on the hydraulic motor, reducing the direct pressure of the hydraulic motor on the planetary reducer 3, making it easier for the hydraulic motor to rotate, and thus making it more convenient for the third threaded hole 25 to be aligned with the fourth threaded hole 31.
[0047] The implementation principle of a hydraulic motor housing with a flange 2 in an embodiment of the present application is as follows: When assembling the hydraulic motor, first insert the positioning convex ring 14 into the second through hole 23, and then rotate the housing body 1 so that the positioning protrusion 15 is embedded in the positioning groove 24. Then, install and fix the housing body 1 and the flange 2 through the first screw 11. Then place the hydraulic motor with the flange 2 on the planetary reducer 3, sleuth the fixed perimeter 26 on the outside of the planetary reducer 3, and then rotate the hydraulic motor so that the output shaft 4 meshes with the driven wheel 32. Then rotate the hydraulic motor again so that the third threaded hole 25 can be aligned with the fourth threaded hole 31, and then install and fix the hydraulic motor and the planetary reducer 3 through the second screw 21.
[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
