Alignment device for long-distance drum-shaped gear transmission dial indicator in confined space

Abstract

The invention discloses a limited space long distance drum-shaped gear transmission dial gauge alignment device. The device is characterized by comprising a first mandrel (1), a second mandrel (2), afirst flange plate (3) and a second flange plate (4), wherein one side of the first mandrel (1) and one side of the second mandrel (2) are connected with a motor end drum-shaped tooth half coupling and a reducer end drum-shaped tooth half coupling respectively, the other sides are connected with one sides of the flange plates, and the other sides of the flange plates are connected with a transmission shaft cylinder. A motor output end is in rigid connection with a reducer input end, the flange plates are guaranteed by a bearing to do 360-DEG rotation, a rigid shaft cylinder can rotate when thecouplings are aligned, moreover, when a motor and a speed reducer cannot rotate, coaxiality adjustment of the long distance coupling is realized by dialing the dial indicator, a problem of alignmentof the long-distance drum-shaped tooth transmission in the narrow space of the site is completely solved, the alignment effect is good, and smooth production and smooth flow are guaranteed.

Description

Technical field: [0001] The invention relates to the technical field of PQF limit-moving mandrel continuous rolling tubes, in particular to a long-distance drum-shaped tooth transmission dial indicator alignment device in a limited space; it is used for alignment of a coupling in a long-distance limited space, It solves the problem of centering and alignment of long-distance drum gear transmission in narrow space on site. Background technique: [0002] The existing PQF460 production line is driven by three motors at the top and bottom respectively. The lower motor is transmitted to the reducer through the middle indirect shaft through the hole of the upper motor base, and the transition is made through a safety coupling in the middle. The distance is longer, the middle links are more, and the space It is very narrow, which makes it difficult to find the alignment; when the equipment is initially installed, a professional manufacturer uses a laser alignment instrument to comp...

Problems solved by technology

[0002] The existing PQF460 production line is driven by three motors at the top and bottom respectively. The lower motor is transmitted to the reducer through the middle indirect shaft through the hole of the upper motor base, and the transition is made through a safety coupling in the middle. The distance is longer, the middle links are more, and the space It is very narrow, which makes it difficult to find the alignment; when the equipment is initially installed, a professional manufacturer uses a laser alignment instrument to complete the alignment and alignment; but as a manufacturer, there is no laser alignment instrument, because it is a drum-shaped gear drive and has a safety coupling The four-table alignment method of the intermediate indirect shaft cannot be used for the transition of the coupling. In the past, due to poor alignment, the reaming bolts of the coupling were frequently loosened and broken, which affected production.
