The invention discloses a tapered roller bearing gap adjustment device and a gear reducer, which include an externally threaded pipe, an internally threaded pipe, a locking spring arm, a rotating body and a flange connected to a box body, an externally threaded pipe, and an internally threaded pipe Through threaded connection, the internally threaded pipe can be rotatably connected to the flange, and the rotating body can be rotatably connected to the inside of the internally threaded pipe. . The inner threaded pipe is provided with a locking elastic arm, and the locking elastic arm is provided with a locking pin that can extend to the radially outer side of the inner threaded pipe, and the radially inner side of the outer threaded pipe is provided with a number of axially distributed locking grooves. There is a swing arm for driving the locking spring arm. In the locked state, the locking elastic arm can safely and reliably avoid the change of the length of the threaded pipe assembly. When the driving rotating body rotates relative to the locking elastic arm, the locking pin and the locking groove can be automatically separated, so that the length of the threaded pipe assembly can be adjusted, and then the bearing clearance can be adjusted.
Description
technical field [0001] The invention relates to the technical field of bearing assembly, in particular to a tapered roller bearing gap adjustment device and a gear reducer. Background technique [0002] Gear reducers are widely used in industries such as automobiles, rolling mills, mining, metallurgy, and plastic machinery, and tapered roller bearings are usually an important part of gear reducers. Tapered roller bearings can provide both radial support and axial thrust. Different from ordinary deep groove ball bearings, tapered roller bearings need to adjust the radial clearance by adjusting the axial distance between the inner ring and outer ring. Therefore, during assembly and later use, it is necessary to regularly check and adjust the axial distance between the angular thrust inner ring and outer ring. [0003] Conventional methods in the prior art are usually achieved by adding gaskets or grinding and adjusting gaskets. During assembly, the radial clearance of the be...
