Abstract

The utility model discloses a vertical-mill rocker-arm rotating-shaft positioning device, which comprises a fixed ring, a self-lubricating bearing, a movable ring, a distance ring, a vertical-mill rocker-arm rotating shaft and a bearing seat; and the vertical-mill rocker-arm rotating-shaft positioning device is characterized in that: the fixed ring is fixed on the bearing seat, the self-lubricating bearing is clamped in the bearing seat through the fixed ring, the distance ring is sleeved in the fixed ring, the movable ring is clamped at the outer side of the fixed ring, and the movable ring and the distance ring are together fixed on the vertical-mill rocker-arm rotating shaft. The vertical-mill rocker-arm rotating-shaft positioning device is applied to the working conditions that a vertical-mill rocker arm has a heavy load, a large span and a larger axial load and the vertical-mill rotating shaft frequently swings at small angles, so that a radial load and the axial load are simultaneously born by the self-lubricating bearing; because the requirements of no maintenance and self-lubrication under long-term use conditions can be met by the self-lubricating bearing, meanwhile, the abrasion problem for the distance ring under the working conditions that the axial heavy load is born by the vertical-mill rocker-arm rotating shaft and the vertical-mill rocker-arm rotating shaft frequently swings at the small angles is solved; and the device has the advantages of simple structure, high reliability and low cost.

Description

A kind of Vertical Mill rocker shaft positioner

Technical field

The utility model relates to a kind of Vertical Mill rocker shaft mechanism, relates in particular to a kind of Vertical Mill rocker shaft positioner.

Background technology

The Vertical Mill rocker shaft is the big span dual-gripper configuration design of bearing bigger radial load and axial load, often came bearing radial force by the biserial spheric roller bearing in the past, the axle head stop assembly bears axial force, its two ends one end is fixed, the other end floats, the so-called inner and outer ring that uses fastenings to retrain bearing that fixedly is meant produces relative displacement with axle, bearing block, realizes the location that whole axle is; So-called floating is meant relative displacement between the outer collar that do not retrain bearing and the static bearing block.And for spheric roller bearing, if comprising the axial load that has impulsive force acts on stiff end bearing ring and the rolling element, even lubricated fully and enough clean environment degree are arranged so, this axial load also is very big to the influence in reduction bearing service life, or even it is fatal, therefore adopt the configuration mode of rolling bearing just to need the special elimination axial load device of design, guarantee axial location and bear axial load by stiff end axle head block, and must be equipped with supporting dry oil lubrication device; Also need dispose special elimination rubbing device to the stiff end wear problems because of the Vertical Mill rocker shaft exists under the low-angle frequent swing operating mode in addition, make that the complexity of Vertical Mill rocker shaft positioner, manufacturing cost increase, reliability reduces;

Otherwise the employing price is lower, intensity is high and can realize that the lubricated self-lubricating bearing of oneself substitutes spheric roller bearing and then can thoroughly overcome the above problems.

The utility model content

The technical problem that the utility model solved is to overcome Vertical Mill rocker shaft positioner complexity in the prior art, cost height, problem that reliability is low, provide a kind of simple in structure, use the Vertical Mill rocker shaft positioner reliable, that cost is low.

The utility model is realized the above-mentioned purpose technical scheme: a kind of Vertical Mill rocker shaft positioner, comprise retainer ring, self-lubricating bearing, rotating ring, distance collar, Vertical Mill rocker shaft and bearing block, described retainer ring is fixed on the bearing block, self-lubricating bearing is clamped in the bearing block by retainer ring, distance collar is enclosed within the retainer ring, rotating ring is clamped in the outside of retainer ring, and rotating ring is fixed on the Vertical Mill rocker shaft with distance collar.

The utility model is applied in Vertical Mill rocking arm heavy load, big span, larger axis under the operating mode of load and Vertical Mill rotating shaft low-angle frequent swing, make self-lubricating bearing bear radial load and axial load simultaneously, because of can satisfying oneself non-maintaining and under long-term service condition, lubricates self-lubricating bearing, solved the Vertical Mill rocker shaft simultaneously and born the wear problem to distance collar under axial heavy duty and the rocker shaft low-angle frequent swing operating mode, this apparatus structure is simple, reliability is high, cost is low.

Description of drawings

Fig. 1 is a cutaway view of the present utility model.

Wherein: the 1-retainer ring; The 2-self-lubricating bearing; The 3-rotating ring; The 4-distance collar; 5-Vertical Mill rocker shaft; The 6-bearing block.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail.

As shown in Figure 1, the utility model Vertical Mill rocker shaft positioner, comprise retainer ring 1, self-lubricating bearing 2, rotating ring 3, distance collar 4, rocker shaft 5 and bearing block 6, described retainer ring 1 is fixed on the bearing block 6, and self-lubricating bearing 5 is clamped in the bearing block by retainer ring.Distance collar 4 is enclosed within the retainer ring 1, and rotating ring 3 is clamped in the outside of retainer ring 1, and rotating ring 3 is fixed on the Vertical Mill rocker shaft 5 with distance collar 4.Distance collar 4 is used for guaranteeing keeping between rotating ring 3 and the retainer ring 1 suitable gap.

During Vertical Mill work, the axial force that transmits from Vertical Mill rocker shaft 5 is delivered to bearing block 6 by self-lubricating bearing 2, retainer ring 1, pass the swing rotation of coming from Vertical Mill rocker shaft 5 and pass to rotating ring 3, distance collar 4, make them center on the axle center rotary oscillation of Vertical Mill rocker shaft 5, self-lubricating bearing 2 is pressed on rotation on the retainer ring 1; Between the lubricated face of retainer ring 1, rotating ring 3, self-lubricating bearing 2, pump into lubricating grease, to guarantee the operate as normal of Vertical Mill rocker shaft positioner.

The utility model is applied in Vertical Mill rocking arm heavy load, big span, larger axis under the operating mode of load and Vertical Mill rotating shaft low-angle frequent swing, make self-lubricating bearing bear radial load and axial load simultaneously, because of can satisfying oneself non-maintaining and under long-term service condition, lubricates self-lubricating bearing, solved simultaneously the Vertical Mill rocker shaft bear under axial heavy duty and the rocker shaft low-angle frequent swing operating mode to the stiff end wear problems, this apparatus structure is simple, reliability is high, cost is low and non-maintaining.

Claims

1. a Vertical Mill rocker shaft positioner comprises retainer ring, self-lubricating bearing, rotating ring, distance collar, Vertical Mill rocker shaft and bearing block; It is characterized in that: described retainer ring is fixed on the bearing block, and self-lubricating bearing is clamped in the bearing block by retainer ring, and distance collar is enclosed within the retainer ring, and rotating ring is clamped in the outside of retainer ring, and rotating ring is fixed on the Vertical Mill rocker shaft with distance collar.
