Abstract
The utility model discloses a mechanical seal uide bushing subassembly, a serial communication port, including two at least uide bushing bodies, the uide bushing body inlays on the inner wall of axle sleeve, and this body cover of uide bushing is on the main shaft, and the uide bushing body is located between axle sleeve and the main shaft, is equipped with the clearance between axle sleeve and the main shaft. The utility model discloses an increase the uide bushing, by original iron material looks mutual friction, become the friction of polytetrafluoroethylene and iron material after changing, improved the reliability of mechanical seal installation, labour saving and time saving, safe and reliable prevents that the main shaft from pulling.
Description
Technical Field
The utility model relates to a uide bushing subassembly especially relates to a mechanical seal uide bushing subassembly, belongs to mechanical seal technical field.
Background
In the installation process of the large mechanical seal, due to the fact that the mechanical seal is too heavy, the spindle is easy to be pulled when the mechanical seal is rubbed on the spindle, the spindle sleeve and the spindle are locked, and the spindle sleeve and the spindle can be scrapped when the spindle sleeve and the spindle are serious, so that labor and time are wasted. Therefore, the problem of installing large mechanical seals is the first concern of technicians.
Disclosure of Invention
the to-be-solved technical problem of the utility model is: the problem of how to avoid mechanical seal to pull the main shaft when epaxial friction, and cause axle sleeve and main shaft locking is solved.
In order to solve the technical problem, the technical scheme of the utility model a mechanical seal uide bushing subassembly is provided, a serial communication port, including two at least uide bushing bodies, the uide bushing body inlays on the inner wall of axle sleeve, and uide bushing body cover is on the main shaft, and the uide bushing body is located between axle sleeve and the main shaft, is equipped with the clearance between axle sleeve and the main shaft.
Preferably, the material of the guide sleeve body is polytetrafluoroethylene.
Preferably, the inner wall of the shaft sleeve is provided with an inner groove, and the inner groove is provided with a guide sleeve body.
Compared with the prior art, the beneficial effects of the utility model are that:
The utility model discloses an increase the uide bushing, by original iron material looks mutual friction, become the friction of polytetrafluoroethylene and iron material after changing, improved the reliability of mechanical seal installation, labour saving and time saving, safe and reliable prevents that the main shaft from pulling.
Drawings
FIG. 1 is a schematic structural diagram of a conventional mechanical seal shaft sleeve;
Fig. 2 is a schematic view of the mechanical seal guide sleeve assembly of the present invention.
Detailed Description
In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
The utility model relates to a mechanical seal uide bushing subassembly, as shown in FIG. 2, it includes first uide bushing body 1, second uide bushing body 2, and the uide bushing body inlays on the inner wall of axle sleeve 3, is equipped with the inside groove on the inner wall of axle sleeve 3, is equipped with the uide bushing body on the inside groove. The guide sleeve body is sleeved on the main shaft 4 and arranged between the shaft sleeve 3 and the main shaft 4, and a gap is formed between the shaft sleeve 3 and the main shaft 4.
When the guiding sleeve is used, the two guiding sleeve bodies (namely the first guiding sleeve body 1 and the second guiding sleeve body 2) are adhered to the inner groove in the inner wall of the shaft sleeve 3 by using specific glue, the mechanical seal is slowly pushed into the main shaft 4 during installation, the polytetrafluoroethylene guiding sleeve mainly rubs with the main shaft 4 during sliding at the moment, the friction coefficient is low, and the guiding sleeve is safe and reliable.
Through the utility model discloses a mechanical seal uide bushing subassembly, mechanical seal (having axle sleeve 3) become present polytetrafluoroethylene- -stainless steel by original stainless steel with the friction of main shaft 4, and coefficient of friction becomes present 0.04 by original 0.3 ~ 0.4, has improved the reliability of mechanical seal installation, and labour saving and time saving, safe and reliable saves labour.
Claims (3)
