Description

实施往复冲击部不同心凸轴固定轴承方法的不同心凸轴固定轴承往复冲击部 技术领域
本发明属于机械领域，具体涉及实施往复冲击部不同心凸轴固定轴承方法的不同心凸轴固定轴承往复冲击部。
背景技术
目前，往复冲击式掘进机掘进时，往复冲击齿垂直于待采掘物往复冲击落料，块料率高、节能环保、效率高，现市场销售块煤的价格是末煤价格的两倍多，因此往复冲击式采掘机具有广阔的使用前景。但在该产品的推广过程中发现，虽然往复冲击式掘进机采掘效率很高，但由于其往复冲击机构的旋转曲轴存在所安装的轴瓦体积小、而所承受冲击反作用大、冲击侧向力大，使旋转曲轴使用寿命极短等问题，又因轴瓦或分体轴承为分体式结构，其抗摆动、抗冲击能力差，且易损坏，损坏后更换、维修困难，因而使往复冲击式采掘机无法长期连续工作，使往复冲击式采掘机难以满足现场使用要求，常用的固定轴承等的挡圈多为卡簧，卡簧作为挡圈使用方便，但用在往复冲击式掘进机的曲轴上，会因所受强大往复冲击振动力及侧向力损坏很快就会变形脱落，造成轴承窜动无法工作，加之其往复冲击落料采掘头不具有向后输料的功能，使往复冲击所落料大量堆积在待采掘面上，不能运至运输系统将物料运走，故严重制约了往复冲击式采掘机的性能及推广应用。

9.耙料离合器设置在耙料旋转件上或设置在动力轴段上或设置在耙料传动件上，不同心连体挡套设置在偏心轴段轴承与动力轴段耙料离合器之间，当耙料臂需旋转耙料时耙料离合器驱动耙料旋转件带动耙料臂旋转，当往复冲击落料时耙料离合器使耙料臂停止旋转，防止耙料臂阻碍冲击落料，解决了往复冲击落料时因耙料旋转臂旋转妨碍往复冲击落料影响摇臂升降等问题，结构巧妙，实用性强。
10.托爪在上限位块和下限位块之间摆动，限位块与箱体分体连接或为一体式，固定轴设置在箱体上，托爪与固定轴铰接，限位块对托爪限位，使托爪处于工作或休止状态，耙料臂旋转耙料时，耙料臂将托爪托起一定角度后通过托爪的旋转空间顺利旋转耙料，当耙料臂反向运动时，托爪在限位块的作用下将耙料臂托住，保持耙料臂处于休止状态。
