Description
技术领域 technical field
本发明涉及圆锥滚子轴承，具体涉及一种防止圆锥滚子轴承外圈旋转的结构。 The invention relates to a tapered roller bearing, in particular to a structure for preventing the outer ring of the tapered roller bearing from rotating.
背景技术 Background technique
圆锥滚子轴承在运转过程中轴承外圈端面与轴承压盖的接触面会发生相对运动，这样就会使轴承的外圈端面与轴承压盖的接触面都造成磨损，从而降低轴承的使用寿命，故需要对轴承的外圈端面进行防转处理。 During the operation of tapered roller bearings, the contact surface between the end face of the bearing outer ring and the bearing gland will undergo relative movement, which will cause wear on the contact surface between the end face of the outer ring of the bearing and the bearing gland, thereby reducing the service life of the bearing. Therefore, it is necessary to carry out anti-rotation treatment on the end face of the outer ring of the bearing.
发明内容 Contents of the invention
本发明的目的在于克服上述不足问题，提供一种防止圆锥滚子轴承外圈旋转的结构。 The object of the present invention is to overcome the above disadvantages and provide a structure for preventing the outer ring of the tapered roller bearing from rotating.
本发明为实现上述目的所采用的技术方案是：一种防止圆锥滚子轴承外圈旋转的结构，包括轴承压盖、销子、圆锥滚子轴承，所述轴承压盖上开设有压盖销孔，所述圆锥滚子轴承的外圈端面对应压盖销孔的位置开设有孔，所述销子的一端固定安装在压盖销孔内，另一端安装在孔内。 The technical solution adopted by the present invention to achieve the above purpose is: a structure for preventing the outer ring of a tapered roller bearing from rotating, including a bearing gland, a pin, and a tapered roller bearing, and a gland pin is provided on the bearing gland A hole is provided on the end surface of the outer ring of the tapered roller bearing corresponding to the position of the gland pin hole. One end of the pin is fixedly installed in the gland pin hole, and the other end is installed in the hole.
所述销子的一端过盈镶装在压盖销孔内，另一端与孔间隙配合。 One end of the pin is interference-fitted in the gland pin hole, and the other end is in clearance fit with the hole.
本发明的特点是：结构简单，便于实现，解决了圆锥滚子轴承运转时轴承外圈与轴承压盖产生相对运动的问题，延长了圆锥滚子轴承的使用寿命。 The invention is characterized by simple structure and easy realization, solves the problem of relative motion between the bearing outer ring and the bearing cover when the tapered roller bearing is in operation, and prolongs the service life of the tapered roller bearing.
