Detailed Description

As shown in fig. 1 and fig. 2, a grease suction and discharge device comprises a shell 1, a power oil cavity 2, a waste oil cavity 3 and a sliding groove 4 are respectively formed in the shell 1, a power oil port 5, an oil suction port 6 and an oil discharge port 7 are respectively formed in the side wall of the shell 1, the power oil port 5 is communicated with the power oil cavity 2, the oil suction port 6 can be communicated with the waste oil cavity 3, the oil discharge port 7 is communicated with the sliding groove 4, a piston 8 is arranged between the power oil cavity 2 and the waste oil cavity 3 in a sliding sealing mode, a sliding column 9 is arranged in the sliding groove 4 in a sliding sealing mode, one side of the sliding column 9 is connected with the piston 8, an oil inlet 10 and an oil outlet 11 which are mutually communicated are respectively formed in the sliding column 9, the oil outlet 11 can be communicated with the oil discharge port. Taking the fan variable pitch bearing automatic lubrication system as an example, the power oil port 5 is connected with the power system, the oil suction port 6 is connected with the bearing oil discharge port, and the oil discharge port 7 is connected with the waste oil collection system. In the grease suction state, the spring 12 is reset to extrude pressure oil in the power oil cavity 2, the sliding column 9 and the piston 8 move towards the power oil port 5, the pressure in the waste oil cavity 3 is reduced, the oil outlet 11 enters the sliding groove 4, the oil outlet 11 is blocked by the shell 1, and when the waste oil cavity 3 is communicated with the oil suction port 6 of the oil discharge port of the butt bearing, the waste oil enters the waste oil cavity 3 due to negative pressure in the waste oil cavity 3. Then the power system injects oil into the power oil cavity 2 through the power oil port 5, the sliding column 9 and the piston 8 move towards the oil drain port 7 and compress the spring 12, so that the piston 8 blocks the oil suction port 6 abutting against the oil drain port of the bearing, the oil outlet 11 is communicated with the oil drain port 7, at the moment, the waste oil cavity 3, the oil inlet 10, the oil outlet 11 and the oil drain port 7 are sequentially communicated, and under the action of pressure, the waste oil enters the waste oil collecting system from the waste oil cavity 3 through the oil inlet 10, the oil outlet 11 and the oil drain port 7. After the power system stops injecting oil into the power oil cavity 2, the spring 12 is reset and enters a grease suction state. The structure uses the spring 12 to reset the sliding column 9 and the piston 8, waste grease can be discharged through pressure generated by oil injection of the power system and elasticity of the spring 12, and in the grease discharging process, oil pipes and valves are not needed to be controlled, so that the oil pipes and the valves are prevented from being maintained and overhauled.

A connecting hole 13 is formed in the sliding column 9, and the oil inlet 10 is communicated with the oil outlet 11 through the connecting hole 13. The oil inlet 10 and the oil outlet 11 are respectively communicated with two ends of the connecting hole 13, the connecting hole 13 not only can play a role of communicating with the oil inlet 10 and the oil outlet 11, but also can play a role of buffering waste oil when the waste oil flows through, and therefore the flow rate of the waste oil is reduced.

An opening is formed in the side of the shell 1, an end cover 14 is arranged at the opening, and the end cover 14 can seal the opening. The end cap 14 is removably mounted to the opening in a configuration that allows the end cap 14 to be opened to facilitate maintenance and inspection of the internal components.

The side parts of the two sides of the shell 1 are provided with openings, the openings are provided with end covers 14, and the openings can be sealed by the end covers 14. The end caps 14 are removably mounted to the openings and this configuration allows the end caps 14 on both sides to be opened to facilitate maintenance and inspection of the internal components.

A sealing ring 15 is arranged between the end cover 14 and the opening. The sealing ring 15 can seal the end cover 14 and the opening, and leakage is avoided.

And a limiting device is arranged in the power oil cavity 2 and is positioned between the power oil port 5 and the oil suction port 6, and the limiting device can block the piston 8. The limiting device can be a bump arranged on the inner wall of the shell 1, and can also be a buffer structure such as a spring, a soft cushion and the like. The limiting device can prevent the piston 8 from blocking the power oil port 5, and prevent oil of a power system from being incapable of being injected into the power oil cavity 2.

The limiting device is a limiting ring 16. The limiting ring 16 can block the piston 8, and the piston 8 is prevented from blocking the power oil port 5. The stop collar 16 may be fitted on the inner wall of the housing 1.

The oil inlet 10 and/or the oil outlet 11 is at least one. The number of the oil inlets 10 and/or the oil outlets 11 can be any number, and when the number of the oil inlets 10 and/or the oil outlets 11 is multiple, the waste oil in the waste oil cavity 3 can be facilitated to flow into the oil drain port 7.

The oil drain cavity 17 is formed in the shell 1, the oil drain cavity 17 is communicated with the oil drain port 7 and the sliding groove 4 respectively, the sliding column 9 can slide into the oil drain cavity 17, and the oil outlet 11 can be communicated with the oil drain cavity 17.
