The bearing grease capping machine is a special equipment for the assembly of the railway truck
bearing seal cover assembly. For a long time, in the course of work, the bearing seal assembly is often biased, misaligned, etc., resulting in component scrapping, increased raw material costs, affecting production, and even the quality of the entire set of bearings are affected. In addition, after the bearing is greased, it can't be reset to the center of the material channel, and it can't realize automatic cutting. Therefore, the staff needs to manually cut and then cut the material. Because the bearing quality is large, the labor intensity of the staff is objectively increased. , affecting production efficiency.
Design
The technical problems arising in the
bearing assembly process were carefully analyzed and discussed, and the uniform grease capping machine was optimized.
(1) Changing the structure and support surface of the gland cylinder increases the support strength and rigidity of the system, ensuring that the system maintains good centering accuracy under frequent pressure shocks.
(2) The original double motor drive homogenization is changed to single motor drive homogenization, which makes the whole structure compact, reduces the axial size, reduces the floor space, and greatly reduces energy consumption.
(3) Adjust the stroke of the action cylinder to ensure that the bearing gland is greased and then pushed to the designated position of the material channel by the reset cylinder to realize automatic cutting.
(4) In the design of the mechanism, the elastic mechanism is added. Before the gland is pressed, the grease friction plates on both sides are under the action of the spring force. Firstly, the bearing is pre-positioned (the friction plate is guided by the spline, and the centering is accurate) to ensure The bearing does not deflect during the movement, and at the same time, it can avoid the problem of gland deflection caused by inaccurate feeding.
