The utility model is characterized in that the outside of the pressing roller (4) is provided with a parted combined type grinding ring equipment; the parted combined type grinding ring equipment comprises a grinding ring sleeve (2) and a grinding ring (3) which installed inside the grinding sleeve (2), the inside of the grinding ring (3) is provided with a roller track matching with the pressing roller (4), the split combined type grinding ring equipment is fixed inside the cabinet (1) by a pressing ring (11) through a bolt (12).
Description
Technical field
The utility model relates to the grinding mill technical field of using roller and bull ring teamwork, particularly a kind of ultra-fine mill with separate assembling bull ring.
Background technology
In the micropowder superfine processing industry, ultra-fine mill is one of main process equipment, and its structure mainly is made up of casing, bull ring, main shaft, rotating disk, pressure roller, bearing pin, cover plate, pressure ring, frame and running part.Bull ring is as the major part in the ultra-fine mill equipment, and the processing performance of the selecting for use of its material, cold and hot working, assembly precision, service life etc. the quality of index will directly affect the quality and the performance of complete machine.The traditional structure form of bull ring is the monolithic construction (see figure 3), select the cast alloy steel casting for use, because volume is big, the planform complexity, be easy to generate defectives such as pore, sand holes, shrinkage porosite in the casting process, bring bigger difficulty to processing and manufacturing, the Technology for Heating Processing performance is also relatively poor, and the mechanical property of material is difficult to be not fully exerted.Operating position analysis from bull ring, material is rolled pulverizing between pressure roller and bull ring raceway, the raceway part that its groundwork district is a bull ring, this zone there are higher intensity, hardness, wearability and anti-fatigue performance requirement, and other parts are only as the supporter of bull ring, need not too high requirement.Bull ring body made in one piece will also will be considered the process of thermal treatment performance simultaneously according to the material of raceway is required carry out selection, has strengthened cost of manufacture, behind the bull ring wear out failure, can only integral replacing, and the use and maintenance cost of equipment is increased relatively.And, existing ultra-fine mill it press roller bearing pin to be directly installed in the pin shaft hole on the rotating disk, owing to also exist mutual motion at work between bearing pin and rotating disk pin shaft hole, a bearing pin drives pressure roller work more than 2 simultaneously during the above structure of particularly two raceways, so this kinematic pair is stressed bigger, serious wear causes rotating disk to be changed again owing to the wear out failure of pin shaft hole, has strengthened the use maintenance cost of equipment.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned the deficiencies in the prior art, and a kind of convenient processing and manufacture, long service life, the ultra-fine mill with separate assembling bull ring that the equipment use and maintenance cost is low are provided.
For achieving the above object, the utility model improves existing ultra-fine mill, it has casing and rack-mounted main shaft on the frame of being fixed on equally, rotating disk is installed on main shaft, on rotating disk, the pressure roller is installed by bearing pin, its design feature is in the arranged outside of pressing roller separate assembling bull ring device to be arranged, said separate assembling bull ring device comprises the bull ring cover and is installed in the interior bull ring of bull ring cover, the raceway that the inboard of bull ring has and presses roller to match, this separate assembling bull ring device by pressure ring by being bolted to box inside.
The ultra-fine mill that has the separate assembling bull ring as mentioned above is equipped with at least two laminations roller on its rotating disk, several corresponding bull rings of the roller number of plies are installed and press in the bull ring cover, and the inboard of each bull ring respectively has a raceway that matches with the pressure roller.
The ultra-fine mill that has the separate assembling bull ring as mentioned above is equipped with pin sleeve in the bearing pin installing hole on its rotating disk, and bearing pin is installed in the pin sleeve.It between bearing pin and the pin sleeve matched in clearance.
Have the ultra-fine mill of separate assembling bull ring as mentioned above, cover plate is installed above the rotating disk at it.
Because the utility model has adopted separate assembling bull ring device, bull ring cover and bull ring can be selected different materials for use, given full play to the mechanical property of material, realized the reasonably combined of each assembly material, improved the manufacturing process performance of member, convenient processing and manufacture on the basis that does not increase design cost, has increased substantially the quality and the service life of product.And pin sleeve is installed on rotating disk, need only changes bull ring and pin sleeve after the wearing and tearing in the use, need not change bull ring cover and rotating disk, thereby reduced the use and maintenance cost of equipment, improved the overall performance of equipment.
Description of drawings
Fig. 1 cuts open figure in of the present utility model, shows its overall structure;
Fig. 2 is the A-A cutaway view among Fig. 1;
Fig. 3 is for cuing open figure in the existing ultra-fine mill.
The specific embodiment
Fig. 1, embodiment illustrated in fig. 2 be that its round box 1 bottom is by being bolted on the frame to the improvement of existing ultra-fine mill.Main shaft 7 bottoms vertically are installed on the frame by bearing holder (housing, cover), and are connected the transmission moment of torsion with motor through belt pulley.Main shaft 7 tops are connected to rotating disk 8 by binding, and rotating disk 8 has four layers of plate, and the pressure roller 4 that is installed on the bearing pin 5 is arranged respectively between adjacent two plates, and promptly present embodiment has 3 laminations roller, and every layer is equipped with 7 pressure rollers.Press roller 4 and 5 of bearing pins to leave certain design gaps, the size in this gap is relevant with material 6 granularities.In each bearing pin installing hole on rotating disk 8 pin sleeve 10 is installed, bearing pin 5 is installed in each pin sleeve 10, and 10 of bearing pin 5 and pin sleeves are matched in clearance.In rotating disk 8 outsides, be provided with a bull ring 3 corresponding to every lamination roller 4, promptly present embodiment is the tricyclic structure with 3 bull rings, the inboard of each bull ring 3 respectively has one and levels 4 raceways that match with a roller with pressing.3 bull rings are assembled in the same bull ring cover 2, and are fixed on casing 1 inboard by pressure ring 11 by bolt 12.On rotating disk 8, cover plate 9 is installed, and leaves certain clearance, in case shotpin axle 5 is scurried out in the course of the work with bearing pin 5 upper surfaces by bolt.
During work, motor drives rotating disk 8 rotations through main shaft 7, presses roller 4 through driving by bearing pin 5 and making high speed rotating at the ring raceway of action of centrifugal force lower edge bull ring 3, and material to be machined 6 is rolled pulverizing.
