The bearing grease capping machine is a special equipment for the installation of the bearing seal assembly of railway trucks. For a long time; during the operation process; the bearing seal cover assembly is often biased and misaligned; the components are invalidated; the cost of raw materials is added; the production is affected; Even the quality of the whole set of bearings is affected. Others; after the bearings are greased; can not be reset to the middle of the material path; can not complete the active cutting; therefore, the operator needs to manually cut and then cut; because the bearing quality is large; Objectively increased the labor intensity of the workers; affected the production power.
The drawing scheme is carefully analyzed and discussed in the technical difficulties presented during the bearing installation process. The uniform grease capping machine is optimized and depicted.
(1) Change the layout and support surface of the gland cylinder; add the support strength and rigidity of the system; ensure the system under frequent pressure shock; can adhere to better centering accuracy.
(2) The original double motor drive homogenization is changed to single motor drive homogenization; the whole machine layout is compact; the axial scale is reduced; the floor space is reduced; and the energy consumption is greatly reduced.
(3) Adjust the stroke of the cylinder; ensure that the bearing gland is greased and then pushed to the specified orientation of the material channel by the reset cylinder;
(4) In the organization depiction; the elastic organization is added; before the gland; the two sides of the grease conflicting piece under the effect of the spring force; the pre-positioning of the bearing is first performed (the conflicting piece is spline-guided; the centering is accurate); The bearing does not deflect during the movement; together, it can prevent the problem of gland deflection caused by inaccurate loading.
The working principle is shown in the drawing; the sealing cover assembly is placed in the gland seats 4 and 6 on the left and right sides. When loading, the bearing inner assembly rolls to the orientation as shown. The gland cylinder piston 2 is rightward under the pressure oil effect. Move; the grease conflicting sheet 5 first touches the left end of the bearing assembly; the thrust bearing inner component moves to the right. Then; the right end of the inner component touches the right side conflict piece. Then; the spring is tightened and the internal component is finished with a certain pressure. Position, move to the right; carry out the gland; announce the signal when the block 3 presses the travel switch K2; indicates that the gland is finished. The motor drives the pulleys 1 on both sides; the torque is transmitted through the spline shaft; The inner ring of the bearing rotates; the end is greased. The grease is adjustable at 0~3min; the grease spindle speed is 150r/min. After the grease is fixed; the cap cylinder piston 2 is retracted; when the block is pressed, the stroke switch K1 is announced. The reset cylinder piston 7 moves to the left under the effect of the pressure oil; the bearing after the gland is pushed back to the initial orientation under the effect of the reset cylinder, the reset cylinder piston retracts; the release stroke switch K3 announces the signal; the workpiece is unloaded; Go to the next cycle.
The conclusion is improved by the description of the uniform grease capping machine; when the function of the pressure cap is equalized; the principle of the action is more scientific and more reasonable; the pressure deviation and misalignment problems in the gland process are dealt with; the quality of the gland is ensured and The loading and unloading is smooth; together; greatly reducing energy consumption; increasing production power.
