Description
Technical field
The utility model relates to technical field of bearings, especially a kind of roller-mill bearing gap adjusting device.
Background technique
Along with battery of mobile phone manufacturing starts fast development, also higher requirement is constantly proposed to battery pole piece rolling equipment, the circle when nonstraightness of the roll bus of pole piece rolling equipment and rolling is beated the standard (bus nonstraightness≤0.001mm that will reach high, round≤the 0002mm that beats), this just needs to provide one to reduce bearing clearance, is convenient to again the gear mechanism improving bearing installation precision.
Current pole piece rolling equipment mainly contains two kinds of structural types on the location and supporting means of roll, a kind of as shown in Chinese patent CN2669378Y, in order to eliminate the play of roller-mill bearing, add one group and be specifically designed to the gap bearing that disappears eliminating main bearing play, pass through pretension, make roll close to a direction, roller-mill bearing rolling element is close to bearing outer ring (precision reference) all the time on some directions, thus precision when ensureing roll running.But the system rigidity of this structural type is poor, mainly structure middle (center) bearing play is large, and roll within the bearing degrees of freedom is large, and play larger shaft strength area is less, and working stability and rigidity are deteriorated.And in order to consider the factor of assembling, need leave fit up gap (0.10 ~ 0.15mm), along with the coping roller in using process, gap can continue to increase, and lifting surface area also can be more and more less, directly causes system stiffness to become poorer and poorer.
The another kind of highi degree of accuracy that adopts adjusts the supporting of gap bearing, bearing play is eliminated by bearing pre-tightened, be commonly used on the higher machine tool chief axis of required precision, its bearing inner race is with tapering, axle journal with matching, also with tapering, is eliminated the play of bearing, and is reached certain pretightening force by the movement of adjustment bearing inner race on axle journal, thus increase the rigidity of bearing, improve positioning precision and the running precision of roll.This structure can apply certain preloading after mounting again, bearing roller and inner and outer ring is made to produce certain predeformation, and keep inside and outside circle to be in impaction state, rolling element and inside and outside circle have good contact stiffness all the time, structural rigidity is better, but cumulative error is comparatively large, time unloaded, testing precision is lower.Precision as bearing is not high enough, and the roll circle glitch detection after general assembly completes reaches≤0.002mm by being difficult to.Chinese patent CN101922507A discloses a kind of rolling bearing system eliminating play, on the basis of the second structural type bearing means, while bearing inner race has tapering, the outer wall of bearing setting sleeve is made also to have certain tapering, thus can self-aligning and there is degree of precision can bear larger load, we find, this bearing inner ring have tapering thus produce pretightening force basis on, also rely on tapering to produce pretightening force between its outer ring and setting sleeve and realize disappearing gap, while increase disappears gap effect, the pretightening force direction produced due to two conical surfaces is contrary, thus realize certain self-aligning effect, but this bearing needs axle journal, bearing inner race, bearing setting sleeve outer wall, and bearing support inwall all processes tapering, with only by axle journal, the bearing that bearing inner race processes tapering is compared, meet same round glitch detection require under higher to the requirement on machining accuracy of axle journal and each parts of bearing means, thus cause whole installation cost too high.
Based on the deficiency of the existing gap bearing means that disappears, provide a kind of precision higher, working life and stability are strong, and the lower-cost gap bearing means that disappears for battery pole piece rolling mill becomes problem demanding prompt solution in prior art.
