Abstract
Description
Technical Field
[0001] The utility model relates to a bearing slip torque measuring device. Background Art
[0002] Bearing is an important component used for rotating support of mechanical body. Bearing usually includes outer ring, inner ring and several rollers. Several rollers are rollingly arranged on the raceway formed between outer ring and inner ring. The inner ring is used to be connected to the rotating shaft, and is connected to external equipment through the outer ring. Before the bearing leaves the factory, it is often necessary to carry out various performance tests, among which the test of bearing slip torque performance is also one of the test items, so as to avoid the bearing from slipping, causing noise or loosening during actual operation. However, there is no special detection instrument for bearing slip torque in the prior art, and there are large differences in the specifications of bearing outer rings and the materials of the installed equipment are also different, which brings great trouble to the detection and verification. In order to solve this problem, this tooling is specially designed. Utility Model Content
[0003] In view of the deficiencies in the prior art, the utility model provides a bearing slip torque measuring device which can quickly detect and has good adaptability.
[0004] To achieve the above-mentioned purpose, the utility model provides a bearing slip torque measuring device, including a torque wrench, a mounting seat, an adapter block and a connecting rod. The mounting seat is provided with a groove portion in which the adapter block can be detachably connected, and the groove portion and the adapter block are anti-rotation fit. The adapter block is provided with a mounting groove, and the mounting groove can be used for the bearing to be tested to be installed therein, and the inner wall of the mounting groove can form an interference fit with the outer ring of the bearing to be tested. The connecting rod is used to be passed through the bearing to be tested and form a positioning fit therewith, and one end of the connecting rod is also provided with an operating groove in which the connecting end of the torque wrench can be inserted.
[0005] The advantages of adopting the above technical solution are: a mounting seat, an adapter block and a connecting rod are provided, a groove portion for detachably connecting the adapter block is provided on the mounting seat, and a mounting groove for installing the bearing to be tested is provided on the adapter block. After glue is poured into the inside of the bearing to be tested to form a whole, the bearing to be tested is firstly interference-connected with the inner wall of the mounting groove of the adapter block through its outer ring, and then the adapter block is connected to the bearing to be tested and installed in the groove portion of the mounting seat, and then the connecting rod is passed through the inner ring of the bearing to be tested to the bearing to be tested to form a positioning fit with the bearing to be tested, and finally the torque wrench is inserted into the operating groove to complete the installation. After the test is completed, the connecting rod is rotated to drive the bearing to be tested to rotate. When the outer ring of the bearing to be tested rotates relative to the mounting groove of the adapter groove, the reading of the torque wrench is observed to determine the slip torque of the bearing to be tested. Before the test, the type and material of the adapter block can be adjusted to make the adapter block correspond to the bearing to be tested and the use environment of the bearing to be tested. Then, the bearing to be tested and the adapter block are connected, so that the device can better adapt to bearings of different specifications and the use environment of the bearings. After starting the test, you only need to connect the adapter block and the mounting seat, the connecting rod and the bearing to be tested to facilitate the test.
[0006] The utility model can be further configured as follows: the adapter block is configured in a polygonal shape, the shape of the groove portion corresponds to the adapter block, a limiting edge is configured below the groove portion, and the limiting edge can abut and cooperate with the bottom of the adapter block.
[0007] Through further settings, the adapter block is set into a polygon, and the shape of the groove is made to correspond to it. After the adapter block is installed into the groove, the anti-rotation effect is achieved through the shape matching between the two. Then, a limiting edge is set under the groove to abut against the bottom of the adapter block, so as to achieve the vertical limiting effect and facilitate the installation of the adapter block.
[0008] The utility model can be further configured as follows: the adapter block is provided with a plurality of screw holes located at the corners, the limiting edge is provided with a plurality of bolts at the positions corresponding to the screw holes, the bolts are sleeved with elastic parts, and the two ends of the elastic parts are respectively in contact with the cap of the bolt and the limiting edge.
[0009] Through further arrangements, screw holes and bolts are respectively arranged on the adapter block and the limiting edge, and a plurality of bolts are arranged on the limiting edge, and elastic parts are mounted on the bolts, which are respectively in contact with the cap and the limiting edge of the bolts. This enables the bolts to maintain an initial position under the action of the elastic parts in a normal state, and after the adapter block is installed, the bolts can be pushed to overcome the elastic force and be inserted into the screw holes, and then rotated to form a threaded fit, which is convenient for installation.
[0010] The utility model can be further configured as follows: an abutment portion and a threaded portion are also provided on the connecting rod, the abutment portion is provided below the operating slot, and the abutment portion can abut and cooperate with the bearing to be tested, the threaded portion is provided at the other end of the connecting rod, and a nut threadedly engaged therewith is provided at the threaded portion.
[0011] Through further configuration, an abutment portion and a threaded portion are provided on the connecting rod, the abutment portion is provided below the operating groove, and the threaded portion is provided at the other end of the connecting rod for nut installation, and the bearing to be tested is clamped and positioned by the abutment portion and the nut, so that after the torque wrench is subsequently installed, the bearing to be tested can be driven to rotate by rotating the connecting rod.
[0012] The utility model can be further configured as follows: the operation slot is configured in a rectangular shape.
[0013] Through further configuration, the operating slot is configured to be rectangular, so that the connecting rod and the torque wrench can be conveniently anti-rotated. BRIEF DESCRIPTION OF THE DRAWINGS
