Description
Technical field
The present invention relates to roll, specifically double planetary systems roll.
Background technology
Planetary rolling, from roll system structure, can be divided into double-planet roller mill and single file star roller mill.In the planetary rolling built up, the overwhelming majority is double-planet roller mill, as shown in Figure 1.
Double-planet roller mill (as shown in Figure 1) equipment is complicated, and production accident is many, and operating rate is low, particularly tight to the synchronous requirement of little working roll to upper and lower tens, slightly lack of proper care, just may cause the accident such as " accordion " or " large tail ", to connect when rolling more so; In addition, workroll bearing consumption is large, the life-span is short and change not easily.
Single file star roller mill (as shown in Figure 2) only adopts a planetary rollers, there is not upper working rolls and lower working rolls stationary problem, simplify milling train mechanism, enhance functional reliability, meanwhile, planetary rollers running part can save pinion stand and universal-joint spindle, is separated circle external diameter not by the restriction of planetary rollers size, outlet guide is simple, makes operation and keeps in repair more convenient.But, because its planetary rollers structure is still identical with double-planet roller mill. be separated coil structures complexity and still must drive separately. mill star-up complicated operation, especially workroll bearing and hold-down mechanism complexity thereof, service life is short, it is difficult to change, and connects the problem of rolling and is not still resolved.
Compound planetary mill (cpm) (as shown in Figure 3) simplifies further to form on the basis absorbing single file star roller mill advantage, adopts the retainer of rigid unitary to replace the separation circle of protoplanet roller, eliminate planetary rollers left and right sychronisation; Adopt the outer race of special construction to compress working roll, eliminate workroll bearing and bearing block and hold down gag thereof; Adopt outer race and supporting base, eliminate and be separated circle auxiliary drive.
Above-mentioned planetary rolling is single file galaxy milling train, and comprise a planetary rollers and a common plain-barreled roll, namely only have a set of planetary rollers system outside each backing roll, each planetary rollers is stressed separately, and it is as shown in Figure 4 stressed.After planet mill star-up, when not yet entering as-rolled condition, planet roller surface and backing roll surface are without relative sliding; After steel billet is nipped, the horizontal component of VD is just consistent with the feeding speed VG of steel billet, fricton-tight between the two, and the speed VC of this time-division height circle has just become, thus causes the VC being separated circle to reduce, and working roll skids at A point; Along with the rotation being separated circle, multiple working roll order is depressed and forges steel billet, skidding also appears in the contact point of working roll and steel billet, therefore working roll is not only by the power pointing to backing roll center, also bear larger tangential force simultaneously, when first contact steel billet, tangential force belongs to the impulsive force forged, and will cause the bending of working roll and fracture.Therefore design and roll forming and long service life, double planetary systems roll stable, easy to maintenance can be kept very necessary.
Summary of the invention
The object of this invention is to provide and a kind ofly can keep roll forming and long service life, double planetary systems roll stable, easy to maintenance.
For achieving the above object, the present invention adopts following technical scheme:
Double planetary systems roll, comprise backing roll and working roll, the support roll shaft at backing roll two ends is connected with support by clutch shaft bearing, it is characterized in that supporting on roll shaft and be provided with separation circle, be separated circle to be connected with support roll shaft by the second bearing, be separated on circle and be furnished with interior garden week hole slot, be separated on circle and be evenly arranged a circle axis hole, lateral surface around backing roll has been evenly arranged a circle intermediate calender rolls, the two ends of each intermediate calender rolls are fixed in interior garden week hole slot by positioner and pressure strip, the side of each intermediate calender rolls is all tangent with the side of backing roll, the two ends of working roll are connected with axis hole with axle sleeve by the 3rd bearing, the side of two operated adjacent rollers and the side of same intermediate calender rolls tangent, the radial direction of working roll is by pressing plate, bolt and elastic washer location, be separated between the inner side of circle and the outside of backing roll and be provided with wearing piece.
Due to working roll planetary system of the present invention and intermediate calender rolls planetary system be placed in same be separated circle in, each working roll is supported by two intermediate calender rolls, normal force suffered by working roll passes to backing roll by two backing rolls, tangential force suffered by each working roll is born by two intermediate calender rolls and is passed to next working roll, simultaneously, time stressed, backing roll, intermediate calender rolls and working roll compress mutually, rolling friction is between roll surface, without skidding, therefore, stress is fully optimized, and is conducive to keeping roll forming and reducing wearing and tearing.The present invention is stable, easy to maintenance.
