Abstract
The utility model provides a lantern ring and particularly relates to a lantern ring for engineering machinery. The lantern ring for the engineering machinery comprises a ring body, a mounting hole is arranged in the ring body, and an inner mounting ring groove and an outer mounting ring groove are disposed in the mounting hole, and the inner mounting ring groove and the outer mounting ring groove are arranged in connecting mode. A middle sealing groove is arranged in the middle of the upper portion of the ring body, a matching position is arranged on the left end of the bottom of the ring body, and a pair of outer sealing grooves is arranged on the outer wall of the tail portion of the ring body. A clamping groove is arranged between the outer sealing grooves, and an oil-way is arranged in the ring body. The lantern ring for the engineering machinery is compact in structure, high in mounting accuracy and strong in tightness.
Description
Technical field
The utility model is a kind of isolating ring, particularly a kind of isolating ring for engineering machinery.
Background technique
Isolating ring assembly precision of the prior art is low, and usability is not enough to some extent simultaneously, so that using effect descends.
Chinese patent 200820023439.6 discloses a kind of oil seal isolation ring, belongs to mechanical field, comprises body, oilhole, oil duct, and its difference is that the external diameter of body is provided with oil duct, and being provided with between the internal diameter of body and the external diameter can be by the oilhole of lubricant oil.This structure is relatively simple, and sealing is relatively poor simultaneously, and simultaneous adaptation is not strong.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, compact structure, and improving product sealing, the isolating ring that is used for engineering machinery that assembly precision is high.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of isolating ring for engineering machinery, comprise ring body, be provided with pilot hole in the described ring body, be provided with interior assembling ring recess and outer assembling ring recess in the described pilot hole, the distribution that is connected with outer assembling ring recess of described interior assembling ring recess, the top interposition of described ring body is provided with the intermediate seal groove, the left end of described ring body bottom is provided with and connects the position, the afterbody outer wall of described ring body is provided with a pair of external sealed groove, is provided with draw-in groove between described external sealed groove, is provided with oil circuit in the described ring body.
As preferably, be provided with fastener hole in the described draw-in groove, a port of described oil circuit is positioned at the outer side wall of ring body, and the another port of described oil circuit is arranged in and connects the position.
As preferably, the degree of depth of described interior assembling ring recess is less than the degree of depth of outer assembling ring recess, and described interior assembling ring recess is connected by hypotenuse with outer assembling ring recess, and the angle of inclination of described hypotenuse is 45 degree, and described outer assembling ring recess is positioned at the head of pilot hole.
Therefore, the isolating ring that is used for engineering machinery that the utility model provides, compact structure, assembly precision is high, and sealing is strong.
