Abstract

The utility model relates to a bearing, in particular to an internal tensioning bearing. The internal tensioning bearing comprises an internal tensioning tail shaft, a pair of tail wheels and a pair of internal tensioning bearing seats, wherein the pair of tail wheels are symmetrically arranged on the left side and the right side and are sheathed on the two sides at the middle part of the internal tensioning tail shaft respectively, the pair of the internal tensioning bearing seats are symmetrically arranged on the left side and the right side and are sheathed on the two ends of the internal tensioning tail shaft respectively, and the internal tensioning bearing is further provided with a pair of bearing outer covers which are sheathed outside the internal tensioning bearing seats. The internal tensioning bearing adopts the method that a balancing weight is directly sheathed on the internal tensioning tail shaft, so that various parts of the internal tensioning bearing are connected more tightly due to the action of tension, the vibration during the running is reduced, and the running is more stable.

Description

Interior tensioning bearing

Technical field

The utility model relates to a kind of bearing, is specifically related to a kind of interior tensioning bearing.

Background technique

In equipment such as conveyor, bearing is extremely important parts, and the normal operation of machine all needs sprocket wheel to drive.Since now the conveying capacity of equipment such as conveyor is required more and more higher, also more and more higher to the requirement of the mechanical property of bearing.

Interior tensioning bearing is the bearing of the present adaptation high strength operation of using always, it is generally fixed by bearing support by interior tensioning tailing axle and tail wheel and constitutes, but the stress that such structure produces bearing in the running can be very big, and, such connection is comparatively loose, and the vibrations during running are also bigger.And general conveyor working environment is more abominable, and parts long term exposure such as bearing support are easily invaded by impurity such as dust outside, cause the damage of bearing.

The model utility content

It is tight that the purpose of this utility model provides a kind of structure, operate steadily, and effective tensioning bearing in the dust-tight.

Above-mentioned technical purpose of the present utility model is achieved by the following technical programs:

Interior tensioning bearing, tensioning tailing axle, tail wheel and interior tensioning shaft bearing in comprising, described tail wheel is symmetrical a pair of, and both sides, tensioning tailing axle middle part in being set in respectively, the tensioning shaft bearing is symmetrical a pair of in described, and the two ends of tensioning tailing axle in being set in respectively, the tensioning bearing also is provided with a pair of balancing weight in described, described balancing weight is separately positioned on the outside of tail wheel, and directly be set on the interior tensioning tailing axle, the tensioning bearing also is provided with the pair of bearings outer cover in described, and described bearing outer cover is set in outside the interior tensioning shaft bearing.Method in the utility model adopts balancing weight directly is set on the tensioning tailing axle makes each parts of the utility model more tight because the effect of pressure connects, and the vibrations when reducing to move, and makes that operation is more steady; The utility model also is provided with the bearing outer cover outside interior tensioning shaft bearing, make whole interior tensioning shaft bearing and external environment separate, and plays well dustproof, grease proofing effect.

Interior tensioning shaft bearing is made up of axle sleeve, bearing shell and square plate, and on the tensioning tailing axle, described bearing shell was set in the axle sleeve outside in described axle sleeve was set in, and described side's sleeve-board is located at the bearing shell outside.

As preferably, bearing shell and axle sleeve are made by Cr12.The utility model utilizes Cr12 to make the critical component of interior tensioning shaft bearing, and the tensile strength of the critical component of tensioning shaft bearing is stronger in making, wear-resisting property is better.

In sum, the utlity model has following beneficial effect:

1, the method in the utility model adopts balancing weight directly is set on the tensioning tailing axle makes each parts of the utility model more tight because the effect of pressure connects, and the vibrations when reducing to move, and makes that operation is more steady; The utility model also is provided with the bearing outer cover outside interior tensioning shaft bearing, make whole interior tensioning shaft bearing and external environment separate, and plays well dustproof, grease proofing effect;

2, the utility model utilizes Cr12 to make the critical component of interior tensioning shaft bearing, and the tensile strength of the critical component of tensioning shaft bearing is stronger in making, wear-resisting property is better.
