## Abstract

A machine assembly bushing temperature detecting system is disclosed. The system includes multiple temperature measuring components, leads and oil resistance component separately connected with the temperature measuring components. The oil resistance component includes process connecting bolt, multi-point fixing piece, locking screws for connecting the process connecting bolt and the multi-point fixing piece. The locking screw is sleeved in the multi-point fixing piece. One end of the multi-point fixing piece is provided with convex structure. A compressing structure is provided in the locking screw to coordinate with the convex structure. The locking screw is in thread connection with the process connecting bolt. The compressing structure is moved away from or pressed against the convex structure by rotation of the locking screw relative to the process connecting bolt.

## Claims

### Claim 1

A machine assembly bushing temperature detecting system, comprising a plurality of temperature measuring components, leads and oil resistance component separately connected with the plurality of temperature measuring components;
the oil resistance component comprises process connecting bolt, multi-point fixing piece, locking screws for connecting the process connecting bolt and the multi-point fixing piece; the locking screw is sleeved in the multi-point fixing piece;
one end of the multi-point fixing piece is provided with convex structure; a compressing structure is provided in the locking screw to coordinate with the convex structure; the locking screw is in thread connection with the process connecting bolt; the compressing structure is moved away from or pressed against the convex structure by rotation of the locking screw relative to the process connecting bolt;
a plurality of jacket through holes are arranged on the multi-point fixing piece, and an armor sealing sleeve is arranged in each of the jacket through holes, and the leads pass through the armor sealing sleeve; a high temperature resistant sealant for sealing the lead in the armor sealing sleeve is arranged in the armor sealing sleeve;
an other end of the multi-point fixing piece is sleeved with a compressing screw; a high temperature resistant O-shaped sealing ring is arranged between the outer wall of the armor sealing sleeve and the inner wall of the jacket through hole; the compressing screw compresses the high-temperature resistant O-shaped sealing ring through a compressing structure; the compressing structure comprises a pressing column pressed on the O-shaped sealing ring and a pressing plate pressed on the pressing column;
the temperature measuring components are firstly inserted into temperature measuring positions in the machine assembly, and each leads is arranged inside the machine assembly through the fixing clip;
the leads pass through the process connecting bolt and the process connecting bolt is tighten to the process interface on the machine assembly; the locking assembly is inserted into the multi-point fixing piece and the leads pass through the multi-point fixing piece, so that the armor sealing sleeve is passed through the multi-point fixing piece;
the locking screw is tightened because the multi-point fixing piece and the process connecting bolt are connected by a movable locking screw; a surface sealing between the multi-point fixing part and the process connecting bolt is achieved by tightening the locking screw; the O-shaped sealing ring, the pressing column and the pressing plate are sequentially fitted into the armor sealing sleeve; the pressing screw is connected with the multi-point fixing piece through the leads, and the pressing plate can be pressed with a balanced force by tightening the pressing screw.

### Claim 2 (depends on 1)

The bushing temperature detecting system of claim 1, wherein an O-ring blocking protrusion is arranged in the inner wall of the lead through hole, and the O-ring is pressed on the O-ring blocking protrusion.

### Claim 3 (depends on 1)

The bushing temperature detecting system of claim 1, wherein the pressing plate is provided with a plurality of lead through holes, and the leads pass through the lead through holes.

### Claim 4 (depends on 1)

The bushing temperature detecting system of claim 1, wherein each of the leads is provided with a fixing clip for fixing the lead in the machine assembly.

### Claim 5 (depends on 1)

The bushing temperature detecting system of claim 1, wherein the process connecting bolt is connected to a process interface on the machine assembly.
