Abstract

The utility model discloses an adjustment disk with anti-loose structure, it includes the adjustment disk, and the adjustment disk has the internal thread, cooperatees with the front bearing lid external screw thread, characterized by: the outer wall of the adjusting disc is provided with an anti-loosening end, and the anti-loosening end and the adjusting disc are integrally formed; the outer wall of the anti-loosening end of the adjusting disc is provided with a 2mm through groove to the inner thread surface of the adjusting disc along the radial direction, the axial center of the anti-loosening end is provided with a through hole to the through groove, the other side of the through groove corresponding to the axis of the through hole is provided with a bolt hole, the diameter of the through hole is larger than that of the bolt hole, the structure is simple, the processing is convenient, and the phenomenon that the bearing box is loosened due to the fact that the loss pretightening force is slowly increased in the operation process of the air compressor bearing box and the thread is.

Description

Adjusting disk with anti-loosening structure

Technical Field

The utility model belongs to the technical field of the air compressor machine, mainly relate to an adjusting disk with anti-loose structure.

Background

The air compressor is an important energy generation form and is widely applied to various links of production and life. Such as machinery, metallurgy, electronic power, medicine, packaging, chemical industry, food, mining, textile, transportation and other fields, become the mainstream products of compressed gas. In the operation process of the air compressor, the phenomenon that the bearing box rotates slowly sometimes occurs because the adjusting disc for fixing the bearing box is connected with the front bearing cover through threads, but the threads are reduced due to loosening along with the influence of multiple factors such as temperature change, impact, vibration and variable load, the loss of the pretightening force is slowly increased along with the increase of the vibration times, the threads fail, the bearing box is loosened, and the phenomenon that the bearing box rotates slowly occurs.

Aiming at the problems, a novel adjusting disc needs to be developed, the bearing box of the air compressor can be prevented from loosening due to thread failure in the operation process, and the problem that the bearing box needs to be solved is solved through simple structure and convenient processing.

Disclosure of Invention

The utility model aims at providing an adjustment disk with anti-loosening structure, its simple structure, processing are convenient, have prevented effectively that air compressor bearing box from increasing slowly because of the pretightning force of loss at the operation in-process, and the screw thread is inefficacy, leads to the phenomenon that the bearing box pine takes off.

In order to achieve the above purpose, the utility model provides a technical scheme is: it includes the adjustment disk, and the adjustment disk has the internal thread, cooperatees with the front bearing lid external screw thread, characterized by: the outer wall of the adjusting disc is provided with an anti-loosening end, and the anti-loosening end and the adjusting disc are integrally formed; a2 mm through groove is formed in the outer wall of the anti-loosening end of the adjusting disc along the radial direction to the inner thread surface of the adjusting disc, a through hole is formed in the axial center of the anti-loosening end, the through groove is formed in the axial center of the anti-loosening end, a bolt hole is formed in the other side of the through groove corresponding to the axis of the through hole, and the diameter of the through hole is larger than that of the.

Further, the anti-loose end may be provided in plurality on the adjustment disk.

The utility model has the effects that: the novel bearing box has the advantages of being simple in structure and convenient to machine, and effectively preventing the phenomenon that the bearing box is loosened due to the fact that the pretightening force of the bearing box of the air compressor is slowly increased and the threads are invalid in the operation process.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-4, the bearing box 2 is installed between the adjusting disk 1 and the front bearing cover 3, and the adjusting disk 1 is connected with the front bearing cover 3 through a screw thread, and the adjusting disk 1 is rotated to tightly install the three parts together. Insert the back with bolt 4 from the through-hole 6 of locking end 5, screw in the bolt hole 7, until the hexagon head nut of bolt 4 and the terminal surface full contact of locking end 5, continue pretension bolt 4, cause locking end 5 bolt hole 7 one side will be because the effect of bolt 4 pulling force is to through-hole 6 one side slope, lead to the cooperation screw thread between front bearing cap 3 and the adjustment disk 1 to take place elastic deformation, increased the relative pivoted frictional force of this place screw thread, thereby realized locking. The problem of air compressor machine bearing box 2 take place the phenomenon of slow rotation in the operation engineering is solved.

The above description is only exemplary of the present invention, and is not intended to limit the scope of the present invention. Any person skilled in the art should also realize that such equivalent changes and modifications can be made without departing from the spirit and principles of the present invention.

Claims

1.
