Description

Technical Field

[0001] This utility model belongs to the field of mechanical testing technology, specifically relating to a multi-gear transfer case testing device. Background Technology

[0002] The multi-gear transfer case is a component in metallurgical rolling mill equipment responsible for power transmission between the front and rear rolling mill rollers.

[0003] Since the transfer case is assembled from multiple sets of gear shafts and bearings, problems such as excessive rotational load causing motor overload and power tripping, and bearing overheating and damage due to overly tight bearing clearance adjustments often occur when the transfer case is put directly into use after assembly, resulting in equipment failure and shutdown.

[0004] However, since the transfer case is assembled on-site and comes in various sizes with different input shaft positions, there is currently no professional multi-gear transfer case testing device on the market. Therefore, there is an urgent need to design a multi-gear transfer case testing device to conveniently and safely conduct offline test rotation of the transfer case, ensuring that the transfer case passes the test before going online and avoiding equipment failure after going online. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multi-gear transfer case testing device that can conveniently and safely perform offline test rotation of the transfer case, ensuring that the transfer case passes the test before going online and avoiding equipment failure after going online.

[0006] To achieve the above objectives / to solve the above technical problems, this utility model adopts the following technical solution:

[0007] This utility model provides a multi-gear transfer case testing device, including a device base, a transfer case base and a motor base;

[0008] The transfer case base is fixedly connected to the device base, and its top surface is used to fix the transfer case.

[0009] The motor base is movably and fixedly connected to the device base, and its top surface is used to fix the motor base.

[0010] The above setup achieves the following effects: the transfer case base and the motor base are used to connect the transfer case and the motor, respectively, thereby fixing the relative positions of the transfer case and the motor, ensuring a firm connection between the motor output shaft and the transfer case input shaft, and enabling relatively convenient and safe offline test rotation of the transfer case. This ensures that the transfer case passes the test before going online, preventing equipment failure after going online.

[0011] During use, hoist the multi-gear transfer case to be tested onto the transfer case base and secure it firmly. Adjust the position of the motor base according to the position of the transfer case input shaft and securely fix the motor base onto the device base. Hoist the motor onto the motor base, connect the power cord of the electrical control device to the motor, and operate the handle to rotate the motor, causing the transfer case to rotate for test operation.

[0012] Further configuration: The top surface of the motor base is fixedly connected to the motor via an adjustment device;

[0013] The adjustment device is used to adjust the center height of the motor.

[0014] The above setup achieves the following effect: There is usually a height difference between the center of the motor output shaft and the transfer case input shaft used for measurement. Directly replacing the motor base is troublesome, costly, and requires disassembly and fixation. Therefore, this utility model changes the distance between the motor and the motor base by adjusting the device, thereby aligning the center of the motor output shaft and the transfer case input shaft. After adjustment, the motor and base are firmly fixed, and the motor output shaft and the transfer case input shaft are firmly connected, thereby increasing the universality and economy of this testing device and improving the ease of operation.

[0015] Furthermore, the adjustment device includes multiple adjustment pads of different thicknesses, which are used to place between the motor base and the motor.

[0016] The above setup achieves the following effect: by using adjustment pads of different specifications on the motor base, the center height of the motor can be adjusted to ensure the connection between the motor and the input shaft of the transfer case. Therefore, this device can meet the testing requirements of multi-gear transfer cases of different specifications.

[0017] Furthermore, the adjustment device includes an adjustment screw fixed on the top surface of the motor base, an adjustment pad slidably sleeved on the adjustment screw, and an adjustment nut movably connected to the adjustment screw;

[0018] The adjusting pad is provided with a through hole with a diameter larger than that of the adjusting screw, and the adjusting screw passes through the through hole, thereby allowing the adjusting pad to be slidably sleeved on the adjusting screw;

[0019] The adjusting screw is threaded, and the adjusting nut is engaged with the adjusting screw and located below the adjusting pad; the adjusting nut moves along the adjusting screw by rotation and abuts against and fixes the adjusting pad.

[0020] The above settings achieve the following effect: by adjusting the rotation of the adjusting nut, the adjusting screw moves up and down, thereby adjusting the distance between the adjusting shim and the top surface of the motor base, thus adjusting the center height of the adjusting motor.

[0021] Furthermore, the adjusting pad is square, with four through holes distributed at its four corners;

[0022] There are four adjusting screws, which are vertically fixed to the top surface of the motor base, corresponding to the positions of the four through holes.

[0023] The above setup achieves the effect of making the four adjusting screws more secure.

[0024] Furthermore, the adjusting pad is provided with mounting holes three corresponding to the mounting holes at the bottom of the motor;

[0025] The top plate of the transfer case base is provided with mounting holes two corresponding to the transfer case foot holes.

[0026] The above setup achieves the following effect: it allows for quick and easy fixing via mounting holes.

[0027] Furthermore, the device base has multiple sets of bolt holes distributed along the length of the transfer case base next to it;

[0028] The bottom of the motor base is provided with mounting holes that are compatible with the bolt holes of each group;

[0029] The motor base and the device base are movably and fixedly connected by adjusting bolts that pass through the bolt holes and mounting holes.

[0030] The above setup achieves the following effect: the motor base is detachable and movable, and is fixed to the test device base by adjusting bolts distributed on the device base. Therefore, the position of the motor base can be adjusted to meet the power input position requirements of different transfer cases.

[0031] Furthermore, the transfer case base is designed in a fishbone shape, including a main support plate, ribs, and an upper top plate; the bottom of the main support plate is fixedly connected to the device base, and the top is fixedly connected to the upper top plate; the ribs are arranged on the side of the main support plate, with the bottom fixedly connected to the device base and the top fixedly connected to the upper top plate; the upper top plate is provided with mounting holes two corresponding to the transfer case foot holes.

[0032] The above setup achieves the following effect: the fishbone-shaped design of the transfer case base can meet the installation dimensions of all different transfer cases on site, while reducing the weight of the base and saving costs.

[0033] Furthermore, the transfer case base is welded onto the device base.

[0034] Furthermore, the motor base includes a base plate, a cross-shaped support, and a top plate;

[0035] The top plate is fixedly connected to the bottom plate by a cross-shaped support;

[0036] The base plate is provided with mounting hole one, and the top plate is provided with mounting hole two.

[0037] Furthermore, the testing device also includes an electrical control device, which is used to provide power to the motor and operate the motor to meet the offline test rotation of the multi-gear transfer case.
