Abstract
The utility model relates to steel hot-rolled and cold-rolled machine equipment thrust bearing of the roll technical field, specifically a kind of replaceable preloading spring tapered roller bearings.The bearing includes outer ring, rolling element, inner ring and preloading spring component, the preloading spring component includes preloading spring, stop push rod, spring groove, jump-ring slot, in spring groove on cycle surface machining clamp spring slot, preloading spring and stop push rod are limited in bearing face jump-ring slot using spring collar, ring face is stretched out on stop push rod head.The utility model bearing each section part exchanging is convenient, and Spring Card section is smaller, and push rod activity space is big, is not easy stuck, and effectively improving bearing the phenomenon that premature failure, has good persistent and practicability due to preloading spring failure.
Description
Technical field
It is specifically a kind of replaceable the utility model relates to steel hot-rolled and cold-rolled machine equipment thrust bearing of the roll technical field
Preloading spring tapered roller bearing.
Background technique
Field of steel metallurgy milling train mostly uses taper roller thrust bearing, and the included bearing for pre-tightening function can effectively disappear
The insufficient influence to bearing performance and service life, but most of preloading springs used from preloaded bearing are pre-tightened except manually installed
It is not only easily stuck to be disposable, can also occur pre-tightening insufficient and failure phenomenon because of recess.
Summary of the invention
In order to solve the above technical problems, the utility model provides a kind of replaceable preloading spring tapered roller bearing.
For achieving the above object, the utility model uses following technical scheme:
A kind of replaceable preloading spring tapered roller bearing, the bearing include outer ring, rolling element, inner ring and pre-tighten bullet
Spring component, the preloading spring component includes preloading spring, stop push rod, spring groove, jump-ring slot, in spring groove close to outer ring end
Preloading spring and stop push rod are limited in bearing face jump-ring slot by machining clamp spring slot on face using spring collar, and stop pushes away
Club head stretches out ring face.
Compared with prior art, the utility model has the following beneficial effects: bearing each section part exchanging of the present invention is convenient, bullet
Spring card section is smaller, and push rod activity space is big, be not easy it is stuck, effectively improve bearing because preloading spring failure due to premature failure
The phenomenon that, there is good persistent and practicability.
Detailed description of the invention
Fig. 1 the utility model structure diagram；
Fig. 2 the utility model preloading spring component partial structural diagram；
Fig. 3 spring card slot partial enlarged view；
Fig. 4 the utility model installs preloading spring component priority order figure.
Specific embodiment
The utility model is described further below in conjunction with attached drawing.
A kind of replaceable preloading spring tapered roller bearing, the bearing include outer ring 2, rolling element 3, inner ring 4 and pre-
Tight spring assembly 1, the preloading spring component includes preloading spring 5, stop push rod 6, spring groove 9, jump-ring slot 8, in spring groove
Close to machining clamp spring slot 8 on cycle surface, preloading spring 5 and stop push rod 6 are limited in bearing face card using spring collar 7
In spring slot 8, ring face is stretched out on 6 head of stop push rod, forms a pre-tightening apparatus, plays the role of preload.Preloading spring is height
Elastic compression spring plays the role of bearing and preload.Stop push rod compresses spring by shell contact, start-stop movement
With.Spring collar plays position-limiting action by the cooperation with the spring card slot on blind hole hole wall 10.Bearing outer ring end face carries out
Hole machined, as pre-tightening apparatus carrier.When installation, preloading spring is first installed, then stop push rod is installed, Spring Card is finally installed
Circle, for erection sequence as shown in figure 3, spring collar is mounted in card slot, spring card slot is blind hole structure, and retaining spring and push rod are pacified
In spring card slot.
