Abstract

Disclosed are a sealing device, an apparatus and a robot having the same. The sealing device for use between first and second members includes a first sealing component configured to be sealingly connected to the first member; and a second sealing component configured to be sealingly connected to the second member. The first and second sealing components are configured to form at least one dynamic seal with each other in a circumferential direction of the first and second members. The apparatus includes the sealing device. The robot includes a robot arm including at least a first link and the sealing device, wherein the first member is the first link and the second member is a second link, a base or an end-effector connected to the first link.

Dependent claims

A sealing device configured for use between a first member and a second member, comprising:

a first sealing component configured to be sealingly connected to the first member;
and
a second sealing component configured to be sealingly connected to the second member,
wherein the first sealing component and the second sealing component are configured to form at least one dynamic seal with each other in a circumferential direction of the first member and the second member;
wherein the first sealing component comprises a first sealing portion and a second sealing portion;
wherein the first sealing portion is disposed between the first member and the second sealing portion and configured to seal the first member and the second sealing portion in a radial direction of the first member and the second member;
wherein the second sealing component comprises a third sealing portion and a fourth sealing portion;
wherein the third sealing portion is disposed between the second member and the fourth sealing portion and is configured to seal the second member and the fourth sealing portion in the radial direction and an axial direction of the first member and the second member,
wherein the fourth sealing portion is configured to form the at least one dynamic seal with the second sealing portion in the circumferential direction of the first member and the second member;
and
wherein one of the second sealing portion and the fourth sealing portion defines a concave portion and the other of the second sealing portion and the fourth sealing portion is provided with a convex portion, wherein the convex portion is inserted into the concave portion and is in contact with the concave portion to form the at least one dynamic seal in the circumferential direction of the first member and the second member.
