Description
Technical Field
The utility model relates to a double-disc refiner accessory, especially a double-disc refiner's carousel subassembly.
Background
The main mode that double-disc refiner main shaft and carousel hookup in the existing market is involute spline structure, and the carousel is fixed on the carousel core and is cooperated with main shaft involute spline, and the carousel can the axial slip realize that two grinds thick liquid regional clearances are even under the effect of medium pressure. Due to spline machining and assembling deviation, axial deflection of the rotary table can occur, the surface of the rotary table is not parallel to the surface of the static disc, gaps between grinding plates of the pulping machine in the running are not uniform, the fiber pulping effect of different regions is different, and the pulping quality is influenced.
SUMMERY OF THE UTILITY MODEL
The technical task of the utility model is to provide a carousel subassembly of double plate fiberizer to the not enough among the above-mentioned prior art, this carousel subassembly of double plate fiberizer has and to make the carousel realize the axial self-balancing under the medium pressure effect, guarantees that the clearance is even between the abrasive disc, guarantees the characteristics of making beating quality.
The utility model provides a technical scheme that its technical problem adopted is: it includes carousel and carousel core, the carousel setting on the carousel core, the carousel core adopt involute spline structure hookup with the main shaft, carousel and carousel core adopt spherical spline structure hookup, both ends are provided with sphere support, fixed cover and hold-down mechanism respectively about spherical spline structure, the sphere supports and the cooperation of carousel core sphere, fixed cover sets up in the outside that the sphere supported, the outside of fixed cover is provided with hold-down mechanism.
The spherical spline structure comprises a straight-tooth internal spline arranged on the turntable and a spherical external spline arranged on the turntable core, the straight-tooth internal spline is arranged in the middle of the inner cavity of the turntable, and the straight-tooth internal spline is matched with the spherical external spline.
The pressing mechanism comprises a pressing nut and an adjusting nut, the pressing nut is pressed on the fixing sleeve and is in threaded connection with the inner cavity of the turntable, and the adjusting nut is arranged on the outer side of the pressing nut and is in threaded connection with the fixing sleeve.
And a positioning spring ring is arranged between the rotary disc core at the lower part of the spherical support and the fixed sleeve.
The utility model discloses a carousel subassembly of double-disc fiberizer compares with prior art, has following outstanding beneficial effect: the axial self-balancing of the turntable under the action of medium pressure can be realized, the slight axial swing of the turntable compensates the existing deflection, the surfaces of the movable grinding plate and the static grinding plate are always parallel, so that the uniform gap between the grinding plates is ensured, the pulping quality is ensured, and the like.

Detailed Description
The rotating disc assembly of a double disc refiner of the present invention will be described in detail with reference to the accompanying drawings 1 and 2.
The utility model discloses a carousel subassembly of double-deck refiner, its structure includes carousel 1 and carousel core 2, carousel 1 set up on carousel core 2, carousel core 2 and 3 adoption involute spline structures 4 hookups of main shaft, carousel 1 and carousel core 2 adopt spherical spline structures 5 hookups, both ends are provided with the sphere respectively about spherical spline structures 5 and support 6, fixed cover 7 and hold-down mechanism 8, 6 and the cooperation of carousel core sphere are supported to the sphere, fixed cover 7 sets up in the outside that the sphere supported 6, the outside of fixed cover 7 is provided with hold-down mechanism 8.
The pressing mechanism 8 comprises a pressing nut 81 and an adjusting nut 82, the pressing nut 81 is pressed on the fixed sleeve 7 and is in threaded connection with the inner cavity of the turntable, and the adjusting nut 82 is arranged on the outer side of the pressing nut 81 and is in threaded connection with the fixed sleeve 7.
A positioning spring ring 9 is arranged between the rotary disk core 2 at the lower part of the spherical support 6 and the fixed sleeve 7.
The main shaft 3 is connected with the turntable core 2 by an involute spline structure 4, so that the turntable 1 can axially slide on the main shaft 3; the rotary table 1 is connected with the rotary table core 2 by a spherical spline structure 5 for transmitting torque, and is composed of a straight-tooth internal spline 51 of the rotary table 1 and a spherical external spline 52 of the rotary table core 2, so that the rotary table 1 can axially swing under the combined action of the spherical support 6 and the fixed sleeve 7. Because the external spline of the turntable core is spherical, the contact surface area of the straight-tooth internal spline 51 and the spherical external spline 52 is basically unchanged in the deflection process of the turntable 1, and the contact strength of the tooth surface is not influenced. Spherical support 6 and 2 spherical sliding fit of carousel core can realize the carousel axial swing under the hydraulic pressure effect, and positioning spring ring 9 is used for restricting the swing range of carousel 1. Fixed cover 7 and gland nut 81 are used for compressing tightly and fixed sphere supports 6, and adjusting nut 82 screws the direction the same with carousel direction of rotation, screws the opposite direction with gland nut simultaneously, and at rotatory in-process and gland nut interact, can adjust the degree that gland nut compresses tightly, guarantees that the sphere can smoothly slide under suitable fit clearance, can guarantee simultaneously that the clearance is unchangeable.
The above-mentioned embodiments are only for understanding the present invention, and are not intended to limit the technical solutions of the present invention, and those skilled in the relevant art can make various changes or modifications based on the technical solutions described in the claims, and all equivalent changes or modifications should be covered by the scope of the claims of the present invention. The parts of the present invention not described in detail are the known techniques of those skilled in the art.
