Abstract
The utility model relates to a novel milling roller device, which consists of a roller axis (1), a milling roller (2) arranged on the roller axis and a clamp nut (3) positioned at one end of the roller axis, and is characterized in that: a newly added fix screw (4) passes through the clamp nut (3) and is fixed on the milling roller (2). The utility model has the advantages of simple structure, reliable and stable performance, easy manufacture without increasing cost, convenient installation and prolonging service life of milling roller and roller axis.
Description
(1) technical field
The utility model relates to the parts of Raymond mill, is specially the device of pendulum-type grinding roller.
(2) background technology
Pendulum-type grinding roller assembly is the critical piece of raymond mill, and the abrasive dust principle is exactly the purpose that reaches abrasive dust by the centrifugal swing of these parts.Pendulum-type grinding roller assembly mainly is made up of a grinding roller axle and the drive mechanism that rotates that grinding roller, control grinding roller rotate.Because this assembly is enclosed in the cavity by steel plate, when machine runs up, to bump between material and storeroom, material and grinding roller, can produce very high heat, this heat makes grinding roller axle and the grinding roller that is contained on this expand, and the material that constitutes grinding roller axle and grinding roller is different, and its coefficient of expansion is also different.Roller hole and roll shaft on the grinding roller are taper fit, after machine uses a period of time, produce between grinding roller axle and the grinding roller and become flexible, and rub, and finally cause grinding roller and roll shaft to be worn bad.
Generally solving one of loosening way of grinding roller and grinding roller axle is with sledgehammer grinding roller to be squeezed into the grinding roller axle, again axle head load onto two fall, positive nut, the grinding roller rope is tight.Second way is grinding roller heating assembling, but owing to the abrasion-proof manganese steel roller that has can not heat, even the potassium steel after the heat treatment cannot stand violent bump.So the incident of roller and axle of in use damaging because of grinding roller is loosening often has generation.
(3) technology contents
The purpose of the utility model is to overcome in the prior art defective easily loosening between the grinding roller and roll shaft, and a kind of novel Burnisher apparatus is provided.
In order to realize above-mentioned purpose, the utility model is according to following technical scheme.This device by roll shaft, be arranged on grinding roller on the roll shaft, form at the clamp nut of roll shaft one end, the fixed screw that increases newly passes clamp nut and is fixed on the grinding roller.
Several trough is set on grinding roller, enters so that help fixed screw.
Several holes is set on clamp nut.
Superior part of the present utility model is: simple in structure, dependable performance, stable need not increase cost and just can realize.Easy for installation, increased service life of grinding roller and roll shaft.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model vertical view.
(5) specific embodiment
Concrete structure of the present utility model sees also accompanying drawing 1.This device by roll shaft 1, be arranged on grinding roller 2 on the roll shaft, form at the clamp nut 3 of roll shaft one end, the fixed screw 4 that increases newly passes clamp nut 3 fixedly on the grinding roller 2.When grinding roller 2 is installed, earlier grinding roller 2 is enclosed within on the roll shaft 1, and on an end of roller is fixing, fall, two nuts 3 just, grinding roller just has been fixed like this.But along with the rotation of machine, it is loosening to only depend on clamp nut still can produce between grinding roller and the roll shaft.Therefore, increased fixed screw 4 newly, this screw passes that fastening usefulness is fallen, positive nut 3 and being fixed on the grinding roller 2, make grinding roller 2, roll shaft 1 and clamp nut 3 form one, even the thermal expansion of grinding roller and roll shaft is inconsistent, grinding roller can not rotate separately yet, has played dual fixation like this.
Because fixed screw 4 passes clamp nut 3 and fix relatively difficulty on grinding roller 2, so several trough 5 is set on grinding roller 2, several holes 6 is set on clamp nut enters so that help fixed screw.
Claims (3)
1. novel Burnisher apparatus by roll shaft (1), be arranged on grinding roller (2) on the roll shaft, form at the clamp nut (3) of roll shaft one end, is characterized in that the fixed screw (4) that increases newly passes clamp nut (3) and is fixed on the grinding roller (2).
2. novel Burnisher apparatus as claimed in claim 1 is characterized in that: several trough (5) is set on grinding roller (2).
3. novel Burnisher apparatus as claimed in claim 1 or 2 is characterized in that: several holes (6) is set on clamp nut (3).
