Problems solved by technology
[0002] Since the D series reducer uses multiple pads during assembly, sometimes it cannot be positioned or the positioning is inaccurate, and sometimes the reducer will move when it is installed.
Moreover, there are many pads of various specifications, which are easy to lose, difficult to manage, and do not meet the requirements of modern assembly
In addition, during the assembly process of the reducer, after installing the bearing on one side and assembling the corresponding shaft, it is usually necessary to turn the reducer over again to install and position the bearing in the other direction. Among them, if it is some small-sized reducers, it is realized by manual turning. If it is some large-sized reducers, it is sometimes necessary to turn over with the help of certain equipment. The assembly is time-consuming and labor-intensive, and the cost is high.
Moreover, during the assembly process, due to the movement of the reducer and the difficulty in controlling the assembly force, it is easy to cause damage to the bearing.

The invention aims at providing a fixture having a bearing protecting function and used for assembling a D-series speed reducer. The fixture having the bearing protecting function and used for assembling the D-series speed reducer is simple in structural design and capable of greatly reducing labor force and cost, avoiding damage caused by axial force to the end face of a bearing during installation of the speed reducer, prolonging the service life of the speed reducer and improving the strength of the speed reducer. The fixture having the bearing protecting function and used for assembling the D-series speed reducer comprises a chassis and a positioning tray capable of being detachably installed at the top end of the chassis; three positioning through holes are eccentrically formed in the positioning tray; each positioning through hole corresponds to a gear shaft of the D-series speed reducer; positioning blocks are installed in two of the positioning through holes through positioning columns; and the positioning blocks are supported on the top face of the chassis.
Description
technical field [0001] The invention relates to an assembly device of a reducer, in particular to a fixture for assembling a D series reducer with the function of bearing protection. Background technique [0002] Since the D series reducer uses multiple pads during assembly, sometimes it cannot be positioned or the positioning is not accurate, and sometimes the reducer will move during installation after the positioning is completed. And there are many pads of various specifications, which are easy to lose, difficult to manage, and do not meet the requirements of modern assembly. In addition, during the assembly process of the reducer, after installing the bearing on one side and assembling the corresponding shaft, it is usually necessary to turn the reducer over again to install and position the bearing in the other direction. Among them, if it is some small-sized reducers, it is realized by manual turning. If it is some large-sized reducers, it is sometimes necessary to t...
