Description

Technical Field

[0001] The utility model belongs to the technical field of hollow cup motor reducers, and in particular relates to a one-to-many running machine applied to hollow cup motor reducers. Background Art

[0002] like Figure 7 As shown, the coreless motor reducer 200 includes: a housing 01 in the shape of a cylindrical shell, a gear train 02 disposed in the housing 01, and a reducer output shaft 03 for driving the gear train 02 to rotate, and the lower part of the reducer output shaft 03 extends out of the housing 01. The overall volume of the coreless motor is relatively small, and the volume of the coreless motor reducer 200 used in conjunction with it is also relatively small (the outer diameter of the coreless motor reducer 200 is only a few millimeters to tens of millimeters). Since the gears in the gear train are relatively small, in order to make the gear meshing clearance in the most suitable state, the assembled coreless motor reducer needs to be run-in. It should be noted that the description of the structure of the coreless motor reducer 200 in this section only provides background information related to the disclosure of the utility model, and does not constitute prior art.

[0003] The so-called running-in is to run the assembled gear pair with a certain lubricant under no-load or gradually loaded and accelerated conditions, gradually grinding off the unevenness peaks on the meshing surface and increasing the actual contact area of ​​the two contact surfaces, so that the meshing surfaces maintain the most suitable clearance and the best economic benefits.

[0004] In the prior art, patent publication number CN219675469U discloses a reducer testing device, including a base assembly and two groups of transmission assemblies installed on the base assembly, each of the transmission assemblies is connected to a reducer, and each of the reducers is equipped with a motor; the base assembly includes a transmission shaft and two first bevel gears installed on the transmission shaft, the transmission assembly includes a rotating shaft and a second bevel gear installed on the rotating shaft, the second bevel gears of the two groups of transmission assemblies are meshed with the two first bevel gears one by one, and the rotating shaft is connected to the output shaft of the reducer.

[0005] The deficiency of the prior art is that the reducer test device of this structure cannot be applied to the running-in of the hollow cup motor reducer. The specific analysis is as follows: the reducer test device in the prior art uses two pairs of bevel gears to turn, and the simulated operating conditions are different from the operating conditions of the hollow cup motor reducer. It cannot accurately simulate the operating conditions of the hollow cup motor reducer, which affects the running-in effect and also affects the effect of the life and performance test. In addition, in the reducer test device, when performing the running-in test, the upper and lower parts of the reducer are respectively connected to the motor and the adapter flange through the flange structure, while the hollow cup motor reducer obviously does not have a connecting flange structure. The structural reducer test device in the prior art cannot directly and quickly complete the installation of the hollow cup motor reducer.

[0006] Therefore, it is necessary to provide a new one-to-many running machine for hollow cup motor reducer to solve the above technical problems. Summary of the invention

[0040] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0041] The following is combined with Figure 1-7 The utility model of the one-to-many running-in machine applied to the hollow cup motor reducer is further explained.

[0042] The utility model discloses a one-to-many running-in machine applied to a hollow cup motor reducer, comprising: a driving gear 1, a rotating power part connected to the driving gear 1 at the upper part and used to drive the driving gear 1 to rotate, and n sets of running-in execution units 100 arranged around the driving gear 1, where n is a natural number ≥ 2; the running-in execution unit 100 comprises: a driven wheel shaft 5, a driven gear 4 sleeved outside the driven wheel shaft 5, and a workpiece clamping unit arranged above the driven wheel shaft 5; the driven gear 4 is meshed with the driving gear 1, the driven wheel shaft 5 is coaxial with the driven gear 4, and the rotation axis of the driven wheel is Its own axis; the workpiece clamping unit includes a clamping block 6 and a locking screw 7; the clamping block 6 includes a workpiece clamping hole 61 and a main deformation seam 62 respectively penetrating thereon in the up-down direction, one end of the main deformation seam 62 is connected to the workpiece clamping hole 61, and the other end of the main deformation seam 62 extends to an outer side wall of the clamping block 6, the clamping block 6 also includes a locking screw hole 63 penetrating thereon in the front-back direction, the locking screw hole 63 also penetrates the main deformation seam 62, and the locking screw 7 is arranged in the locking screw hole 63; in the same group of running-in execution unit 100, the driven wheel shaft 5 is arranged opposite to the workpiece clamping hole 61.

[0043] It should be noted that the directions of “front”, “rear”, “upper” and “lower” in this invention refer to Figure 3 Directions shown.

[0044] The one-to-many running-in machine applied to the hollow cup motor reducer of the utility model is used to drive the gear train 02 in the hollow cup motor reducer 200 to rotate, so as to realize the running-in of the gear train 02. The hollow cup motor reducer 200 includes: a shell 01 which is in the shape of a cylindrical shell, a gear train 02 arranged in the shell 01, and a reducer output shaft 03 for driving the gear train 02 to rotate, and the lower part of the reducer output shaft 03 extends out of the shell 01. Each set of running-in execution unit 100 can drive a hollow cup motor reducer 200 to run in, that is, the one-to-many running-in machine applied to the hollow cup motor reducer of the utility model can simultaneously load n hollow cup reducers 3, which greatly saves the time of the running-in operation and improves the efficiency.

[0045] More specifically, the coreless motor reducer 200 is a two-stage planetary gear reducer. When in use, a motor connection hole 04 for inserting the coreless motor is provided at one end of the gear train 02 away from the reducer output shaft 03. After the coreless motor is inserted, it meshes with the gear train 02 through the gear, and the reducer output shaft 03 is connected to the driven member.

[0046] In this embodiment, the workpiece clamping hole 61 is used to load the cylindrical shell-shaped housing 01, and the locking screw 7 is used to control the size of the main deformation joint 62, that is, to control the size of the workpiece clamping hole 61 at the same time. Before the running-in operation, the hollow cup motor reducer 200 is inserted downward into the workpiece clamping hole 61, and the reducer output shaft 03 is just docked with the driven wheel shaft 5 below. When the locking screw 7 is rotated, the width of the main deformation joint 62 gradually decreases, and the workpiece clamping hole 61 gradually decreases until the hole wall of the workpiece clamping hole 61 locks the housing 01, and then the locking screw 7 is stopped from rotating to complete the rapid assembly of the hollow cup motor reducer 200. When the running-in operation is completed, the locking screw 7 is rotated in the opposite direction to quickly loosen the hollow cup motor reducer 200, so that the hollow cup motor reducer 200 can be quickly removed after the running-in operation is completed. Finally, the rapid disassembly and assembly of the cylindrical shell-shaped hollow cup motor reducer 200 is realized.

[0047] The rotating power part is used to provide rotational power. The rotating power part can be a motor or a combination of a motor and a reducer. The rotation of the rotating power part can drive the driving gear 1 to rotate. The driving gear 1 is respectively engaged with the driven gears 4 in n sets of running-in execution units 100, and is used to transmit a rotational power of the rotating power part to n driven gears 4 at the same time, forming a one-to-many structure. The driven gear 4 rotates, driving the driven wheel shaft 5 connected to the driven gear 4 to rotate. When running-in, the reducer output shaft 03 is connected to the driven wheel shaft 5, and rotates driven by the driven wheel shaft 5. The rotation of the reducer output shaft 03 drives the gear train 02 in the reducer 3 to rotate, thereby realizing the running-in of the gear train 02.

[0048] According to the specific implementation mode of the utility model, the one-to-many running-in machine applied to the hollow cup motor reducer is applied to the hollow cup motor reducer 200, and the hollow cup motor reducer 200 includes: an outer shell 01 which is in the shape of a cylindrical shell, a gear train 02 arranged in the outer shell 01, and a reducer output shaft 03 for driving the gear train 02 to rotate, and the lower part of the reducer output shaft 03 extends out of the outer shell 01; the side of the reducer output shaft 03 away from the outer shell 01 is a connecting section 031, and one side of the connecting section 031 is provided with a torque transmission plane 032 for transmitting torque; the end of the driven wheel shaft 5 facing the workpiece clamping hole 61 is provided with a concave connecting shaft hole 41, and the shape of the connecting shaft hole 41 matches the shape of the connecting section 031.

[0049] Since the overall volume of the hollow cup motor reducer 200 is very small, the diameter of the reducer output shaft 03 is even smaller, and the weakening of the strength of the reducer output shaft 03 should be reduced during connection. In this embodiment, only a torque transmission plane 032 is set on one side of the connecting section 031, and the driven wheel shaft 5 with a diameter larger than the connecting section 031 is used to form a coupling hole 41, and the coupling hole 41 has a plane that matches the torque transmission plane 032, and the reducer output shaft 03 is plugged into the coupling hole 41 to achieve connection. With this structure, while ensuring smooth torque transmission, it can also minimize the weakening of the strength of the reducer output shaft 03.

[0050] According to a specific embodiment of the present invention, the clamping block 6 further includes an auxiliary deformation seam 64 which passes through it in the up-down direction and communicates with the workpiece clamping hole 61 . The auxiliary deformation seam 64 and the main deformation seam 62 are arranged on both sides of the workpiece clamping hole 61 .

[0051] In this embodiment, when the main deformation joint 62 is opened, the workpiece clamping hole 61 corresponding to the auxiliary deformation joint 64 is subjected to greater force, and the auxiliary deformation joint 64 is provided at this location to prevent the workpiece clamping hole 61 corresponding to the auxiliary deformation joint 64 from being torn due to the opening of the main deformation joint 62. By adding the auxiliary deformation joint 64, the variation range of the workpiece clamping hole 61 can be further expanded, and the installation and removal of the hollow cup motor reducer 200 can be further facilitated.

[0052] According to the specific implementation mode of the present utility model, the clamping block 6 includes: a main clamping block 65, a control block 66 fixed to the top of one side of the main clamping block 65, and a connecting block 67 fixed to the lower part of the other side of the main clamping block 65; the workpiece clamping hole 61 and the auxiliary deformation seam 64 are both located on the main clamping block 65, one side of the main deformation seam 62 passes through the control block 66, and the other side of the main deformation seam 62 extends to a distance from the main clamping block 65, the locking screw hole 63 is located on the control block 66, and the connecting block 67 is provided with a connecting screw hole 68 passing through it from the top and bottom directions; the height of the bottom surface of the main clamping block 65 is higher than the height of the bottom surface of the connecting block 67.

[0053] In this embodiment, the structure of the clamping block 6 is specifically designed, and the main clamping block 65 is used to form the workpiece clamping hole 61. The control block 66 is located at the top of one side of the main clamping block 65. The structure of the control block 66 protruding upward is conducive to providing enough space to form the connecting screw hole 68. During assembly, the bottom surface of the connecting block 67 is located on the plate to be fixed (such as the upper cover plate 8), and the clamping block 6 is fixed to the plate to be fixed by using bolts / screws to penetrate the connecting screw hole 68. After the installation is completed, there is a gap between the bottom of the main clamping block 65 and the plate to be fixed. With this structure, when adjusting the size of the workpiece clamping hole 61, the bottom surface of the main clamping block 65 is unobstructed and can be opened and closed freely.

[0054] In addition, since the bottom of the main clamp 65 is suspended, the main clamp 65 can be slightly deformed on the water surface to avoid a hard connection structure. When the hollow cup motor reducer 200 is not fully installed or there is a deviation in the docking between the driven wheel shaft 5 and the reducer output shaft 03, the rotating power part will generate torque due to misalignment at the moment of starting. The slight deformation of the main clamp 65 can also absorb a certain amount of torque. Therefore, the generated torsional force will not act entirely on the hollow cup motor reducer 200 and the driven wheel shaft 5. After rotating for a period of time, the driven wheel shaft 5 and the reducer output shaft 03 are naturally straightened, and the main clamp 65 returns to its original shape. This structure can greatly improve the smoothness of the action in actual use.

[0055] According to a specific implementation of the utility model, the rotating power part includes a motor 2 and a reducer 3 connected to the motor 2. The one-to-many running-in machine applied to the hollow cup motor reducer also includes a frame, which includes: an upper cover plate 8, a base plate 9 arranged below the upper cover plate 8, a motor mounting plate 10 fixed to the lower part of the base plate 9, and a column 11 connecting the upper cover plate 8 and the base plate 9; the reducer 3 is installed at the lower part of the motor mounting plate 10, and the top of the reducer 3 passes through the motor mounting plate 10 and the base plate 9 at the same time and is connected to the driving gear 1; the driving gear 1 and the driven gear 4 are respectively installed between the upper cover plate 8 and the base plate 9, and the lower part of each driven wheel shaft 5 is rotatably connected to the base plate 9 via a bearing 12.

[0056] In this embodiment, the motor 2 provides rotational power, which is output after being decelerated by the reducer 3. This embodiment further defines the structure of the frame. The upper cover plate 8, the column 11 and the base plate 9 form a frame structure. The gear set (driving gear 1 and driven gear 4) is installed between the upper cover plate 8 and the base plate 9. The motor mounting plate 10 is fixed at the bottom of the base plate 9 to achieve the installation of the motor 2. As can be seen from the above, the frame of this embodiment has good overall stability, and multiple installation areas can be formed, which can complete the regional stable installation of the rotating power parts and the gear set.

When running in, the coreless motor reducer 200 operates under no-load or gradually loaded and accelerated conditions. The fixed base plate 13, the support rod 14 and the base plate 9 form a frame structure as a whole, which protects the motor 2 and the motor speed regulator 15 located therein.

[0060] In this embodiment, the protective cover 16 connects the upper cover plate 8 at the top and the fixed base plate 13 at the bottom, so that the rotating power parts, the motor mounting plate 10, the base plate 9, the driving gear 1, the driven gear 4 and the speed regulator body 151 are all located in a closed space. On the one hand, it is convenient to protect the rotating parts, and on the other hand, it can prevent external dust from entering, ensuring the long-term stable operation of the motor 2, gears, etc. The speed control panel 152 extends out of the device receiving chamber 17, which is convenient for operators to operate from the outside. The protective cover 18 is a detachable structure, which is convenient for opening for maintenance or observing the operation of internal components.

[0066] In this embodiment, 6 sets of running-in execution units 100 are evenly arranged around the axis of the driving gear 1, so 6 sets of hollow cup motor reducers 200 can be installed at one time and the running-in operation can be performed at the same time, which greatly improves the efficiency of the running-in operation and shortens the operation time.
