Abstract
The utility model relates to a following aligning support wheel device for a drying machine. The bundle-free rolling matching of an original support ring and the support wheel is changed into mutually embedded rolling matching, a bearing in the support wheel is changed into an aligning bearing, and a core sleeve and a core shaft are changed into movable fit. The improvement is used to compensate for the error which is necessarily produced in the manufacture and the installation of the support ring, and accordingly, the support wheel and the support ring of the utility model are decreased; the structure is compact, the abrasion of a working surface can be reduced, the power loss can be decreased, and the service life of the support wheel can be extended.
Description
The utility model relates to building materials chemical industry equipment, is a kind of trailing type aligning riding wheel apparatus that is installed on the dryer.
Riding wheel apparatus on existing dryer, what its support roller heart was adorned is a pair of taper roll bearing, and bearing and mandrel are stationary fit, and restrainting rolls does not cooperate its support roller in order to have with backing ring.Drier body will inevitably produce and scratch distortion under the effect of its deadweight and load, and backing ring will depart from the position with axis normal, angular displacement occur.On the other hand, dryer tubular axis must occur in making installation not straight, two backing rings are installed problems such as decentraction, also can cause the position of backing ring skew and axis normal, the problems referred to above will make support roller be contained on the mandrel and the bearing enclose axis can not keep overlapping at work, can produce certain deflection, the axis deviation of bearing will cause the uneven distribution of the inner contact stress of bearing, cause the initial failure of bearing; Support roller and backing ring all are to contact in each moment, transmission process is a curve rather than two face work, contact stress from, easy to wear, kinetic equation loss is big, in addition, in temperature changing process, except rolling friction, also have sliding friction to axial between support roller and backing ring, aggravated the wearing and tearing that support roller is paid, therefore, existing support roller, backing ring are made clumsy solidly.
The purpose of this utility model is to address the above problem, and a kind of trailing type aligning riding wheel apparatus of compact conformation is provided.
Concrete scheme of the present utility model is: change backing ring and support roller into the inter-embedding type rolling and cooperate, to retrain both axial relative motions, eliminate both sliding frictions; Reelect and use self-aligning bearing being contained in bearing in the support roller endoporus; And the core retainer plate of brearing bore assembling was changed into movingly with cooperating of mandrel.
Above-mentioned improvement reduces support roller backing ring of the present utility model, be easy to make, compact conformation, can reduce work and wearing and tearing, reduce kinetic equation loss, improve the life-span of consumption wheel backing ring.
The utility model will be further described below in conjunction with accompanying drawing:
Accompanying drawing is a structure cutaway view of the present utility model.
Embodiment: referring to accompanying drawing, the utility model is contained in the mandrel 1 on the support roller seat 6 by support roller seat 6, is loaded on the core retainer plate 2 on the mandrel successively, holds axle 3, holds shaft-cup 7, support roller 4 and backing ring 5 compositions that roll and cooperate with support roller.Support roller 4 its outer ring faces in the utility model are processed into groove surface, backing ring 5 are loaded in the groove roll (also can be designed as support roller be embedded in the backing ring roll), axially eliminate both relative slips; Simultaneously core retainer plate 2 and cooperating of mandrel 1 are changed into movingly, with the axial displacement of compensation support roller 4 necessity; The moving axle that holds of the present utility model is selected self-aligning bearing for use; With adapt to backing ring in the motion 5 with support roller 4 axis the state when not parallel.
Claims (1)
1. be used for a kind of trailing type aligning riding wheel apparatus on the dryer, has the backing ring that is contained on the drying cylinder, support the support roller of backing ring, be contained in bearing, core retainer plate, mandrel in the support roller endoporus, and the support roller seat that mandrel is installed, it is characterized in that: backing ring is that the inter-embedding type rolling cooperates with support roller, and the bearing that is contained in the support roller is selected self-aligning bearing for use, and core retainer plate and mandrel are changed into movingly.
