The invention discloses a heavy transmission shaft middle bracket assembly with rubber vulcanized on a bearing outer ring, and relates to the field of middle support assemblies; the heavy transmissionshaft middle bracket assembly comprises a fixed support and a ball bearing, the outer ring of the ball bearing is vulcanized with a rubber buffer pad at a low temperature, so that the ball bearing and the rubber buffer pad form an integrated structure; and the ball bearing is directly mounted and fixed with the fixed support through the rubber buffer pad. The heavy transmission shaft middle bracket assembly has the beneficial effects that the machining and assembling procedures of three parts, namely a bearing seat and a snap ring, are reduced, the assembling period is shortened, and the partproduction procedure is simplified; the weight of the middle support assembly is reduced, and the cost of the middle support assembly is reduced; the rubber buffer pad and the bearing are of an integrated structure, interference fit does not exist between the bearing and the rubber buffer pad, the working clearance of the bearing can be effectively controlled, the service life is prolonged, the bearing is reliably fixed, and the bearing is prevented from being disengaged from the rubber buffer pad.

    本发明公开了一种橡胶硫化在轴承外圈上的重型传动轴中间支架总成,涉及中间支架总成领域,包括固定支架和球轴承,所述球轴承的外圈低温硫化有橡胶缓冲垫,使球轴承与橡胶缓冲垫形成一体式结构,球轴承通过该橡胶缓冲垫直接与固定支架安装固定。本发明的有益效果为:减少轴承座、卡环共3个零件的加工以及装配工序缩短装配周期,简化零部件生产工序;减轻中间支架总成重量,降低中间支架总成成本;橡胶缓冲垫与轴承为一体结构,轴承与橡胶缓冲垫之间无过盈配合,可有效控制轴承的工作游隙,提升使用寿命,又可靠的固定住轴承,防止轴承从橡胶缓冲垫中脱出。
