Abstract
The utility model provides good grinding roller equipment of a flour milling machine, which is composed of a grinding roller, a bearing, a bearing box, etc. The bearing is a single row of radial ball bearing, the inner hole of the bearing is a conical hole, and the conical hole is provided with an adapter sleeve. The utility model can conveniently realize the tight fit of a grinding roller shaft and the bearing by regulating the adapter sleeve, and the assembly and the disassembly of the grinding roller are convenient. The utility model has the advantages of reliable operation, low cost, etc.; the utility model is widely used in various flour milling machines.
Description
The utility model relates to a kind of improved cornmill Burnisher apparatus, belongs to materials crusher tool technical field.
Grinding roller is the core component of cornmill, and it has bigger volume and quality, is bearing high rotational speed and load.Grinding roller is through after the certain hour work, and its roll surface has wearing and tearing and damage in various degree, as milling that groove is polished, pockmark etc. appears in roll surface on the roll surface, needs often grinding roller is disassembled roll surface is repaired.The job specification of grinding roller requires grinding roller except that should having higher running accuracy and bearing capacity, also should be convenient to dismounting.
The Burnisher apparatus of existing roller mill has two types: a kind of two axial ends of grinding roller is bearing in the bearing box of body by rolling bearing, the two axial ends of another kind of grinding roller directly is bearing in the sliding bearing of body, wherein, the rolling bearing supporting has two kinds of forms again: a kind of employing spherical aligning ball bearing, a kind of employing single-row radial ball bearing, the endoporus of the former bearing is conical bore or has sleeve, this kind device, the internal taper hole of bearing and sleeve and grinding roller axle are easy to realize having the tight fit of certain magnitude of interference, and be easy to dismantle, but the spherical self-aligning bearing life-span is short, the cost height, it is in the use of cornmill, short then half a year, length is no more than 2 years just to be needed to upgrade, therefore the cornmill that adopts this device is the cost height not only, simultaneously because of frequent replacing bearing, also corresponding use cost and the maintenance load of having increased; Latter's single-row radial ball bearing need lean on certain magnitude of interference because of the tight fit of its brearing bore zero draft, itself and grinding roller axle and realize, so the dismounting of grinding roller is very inconvenient, and fragile bearing and grinding roller axle in the dismounting.The Burnisher apparatus of another kind of employing sliding bearing as long as lubricating oil has the leakage of drop, will pollute the material in the cornmill, is not therefore also had an optimistic view of by industry.For a long time, never have a kind of Burnisher apparatus of cornmill preferably.
The purpose of this utility model is to provide a kind of Burnisher apparatus of cornmill preferably, and grinding roller and bearing can be realized preferably tight fit, should be convenient to dismounting again in this device, and has reliable operation, characteristics that cost is low.
The purpose of this utility model is achieved in that
A kind of cornmill Burnisher apparatus, it comprises grinding roller, bearing, bearing box etc., and its improvement is that described bearing is a single-row radial ball bearing 1, and this brearing bore is a conical bore, and sleeve 2 is housed on the internal taper hole.
Above-mentioned Burnisher apparatus, the bearing outside of described single-row radial ball bearing are resisted against respectively on the seat hole of bearing box.
Above-mentioned Burnisher apparatus, the tapering of described bearing internal taper hole are 1: 5-1: 20.
Burnisher apparatus according to the utility model making, the single-row radial ball bearing of employing mounting strap sleeve on grinding roller, solved the use defective of existing cornmill Burnisher apparatus with not only science but also easy design, have that grinding roller cooperates with bearing closely, easy installation and removal, reliable, low cost and other advantages, can be widely used on the various cornmills.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model structural representation.
Early stage cornmill product, its structure and manufacturing process are more backward, grinding roller install occur often big because of the grinding roller coaxiality error, influence the installation accuracy problem.Select the spherical aligning ball bearing of 111000 or 11000 series at that time for use, can carry out certain compensation the coaxiality error of grinding roller in the assembling.In the last few years, the cornmill product had had significant progress, and the installation accuracy of grinding roller all holds good security on structural design and manufacturing process, but this kind Burnisher apparatus is in use to today always, was not improved accordingly and improved.
The utility model, one sleeve 2 consistent with the internal taper hole tapering is installed on the internal taper hole of single-row radial ball bearing 1, and be loaded on by sleeve on the two axial ends of grinding roller, the two bearings overcoat is resisted against respectively fully on the outer casing seat hole of bearing box, when rotation sleeve nut moves sleeve outward, the male cone (strobilus masculinus) of sleeve can be realized closely cooperating of grinding roller and bearing with the bearing tensioner on the grinding roller axle; After unclamping sleeve, can easily bearing be unloaded from grinding roller together with bearing box, the grinding roller dismounting easily; Simultaneously, when sleeve unclamped, grinding roller can be adjusted the middle position of grinding roller in the body case easily along the axially-movable of grinding roller axis hole, and assembling and positioning is convenient.The taper hole tapering of radial ball bearing can be 1|12, and its external diameter and width can slightly change, but other physical dimension can be by normal structure size, also otherwise designed.
Claims (3)
1. cornmill Burnisher apparatus, it comprises grinding roller, bearing, bearing box etc., it is characterized in that described bearing is single-row radial ball bearing [1], this brearing bore is a conical bore, and sleeve [2] is housed on the internal taper hole.
2. Burnisher apparatus according to claim 1 is characterized in that the bearing outside of described single-row radial ball bearing is resisted against respectively on the bearing box seated hole.
3. Burnisher apparatus according to claim 2, the tapering of described bearing internal taper hole are 1: 5-1: 20.
