Claims9
A liquid injection ring, comprising a ring body, wherein the ring body is provided with a liquid storage chamber and a plurality of liquid guide holes;
- the liquid storage chamber is arranged in a circle around an axis of the ring body;
- an inlet of each of the plurality of liquid guide holes communicates with the liquid storage chamber, and an outlet of each of the liquid guide holes faces an end surface of a to-be-lubricated bearing;
- and
- the liquid guide holes are uniformly distributed in a spaced manner along a circumferential direction of the ring body;
- wherein each of the liquid guide holes comprises a transition hole and a liquid injection hole that communicate with each other;
- the transition hole is in communication with the liquid storage chamber;
- the plurality of the transition holes are uniformly distributed in a spaced manner along the circumferential direction of the ring body;
- the outlet of each of the liquid guide holes is formed by the liquid injection holes
- the plurality of the liquid injection holes are uniformly distributed in a spaced manner along the circumferential direction of the ring body;
- and the diameter of the plurality of liquid injection holes is smaller than that of the transition holes;
- wherein each liquid injection hole penetrates through the ring body and forms two of the outlets respectively in two end faces of the ring body, and the outlets located in the same end face of the ring body are uniformly distributed in a spaced manner along the circumferential direction of the ring body, and
- wherein the volume of the liquid storage chamber is greater than or equal to the sum of the volumes of all transition holes and all liquid injection holes, and the volume of each transition hole is greater than or equal to that of the corresponding liquid injection hole.
