Description

Technical Field

[0001] The utility model relates to the technical field of bucket wheel stacker reclaimers, namely, a device for preventing a spline shaft and a reducer of a bucket wheel stacker reclaimer from loosening, which is used for connecting and preventing a spline shaft of a bucket wheel stacker reclaimer and a spline hollow shaft reducer of a bucket wheel drive. Background Art

[0002] In the prior art, the bucket wheel spline shaft of the bucket wheel stacker reclaimer is connected to the spline hollow shaft reducer by a half reducer flange, which is installed in the groove of the bucket wheel spline shaft and connected to the end face of the reducer low speed shaft through bolts through screw holes to fix the reducer to the bucket wheel spline shaft. In actual applications, since the spline connection is a clearance fit, the bucket wheel mechanism is frequently started, affected by the size of the reducer low speed hollow shaft, and the diameter of the connecting bolt is small, the connecting bolt is frequently subjected to torsion and shear force, resulting in the breaking of the connecting screws, the loosening of the reducer and bucket wheel spline shaft, damage to the internal and external splines, and production interruption. Utility Model Content

[0003] The purpose of the utility model is to provide a reasonable structure and safe use bucket wheel stacker reclaimer spline shaft and reducer anti-loosening device to solve the above shortcomings. It can ensure that the bucket wheel spline shaft and the driving reducer are connected reliably, and the bucket wheel spline shaft and the spline hollow shaft reducer will not loosen, ensuring stable and safe production.

[0004] The technical solution of the utility model is: a bucket wheel stacker reclaimer spline shaft and reducer anti-loosening device, which is characterized in that a plurality of fixed supports are installed on the bearing seat of the bucket wheel spline shaft, the fixed supports are installed on the bearing seat by bolts, and each fixed support is connected to the reducer and the reducer flange of the torque arm by a tensioning screw.

[0005] The above scheme also includes:

[0006] There are three fixed supports, which are arranged along the middle two sides and the top of the bearing seat.

[0007] The top fixed support is connected by two tensioning screws arranged side by side, and the fixed supports on both sides of the middle are connected by one tensioning screw.

[0008] The advantages of the utility model are: 1. The bearing seat is connected with the reducer and the reducer flange of the torque arm at multiple points, which can ensure the reliable connection between the bucket wheel spline shaft and the driving reducer, and there will be no loosening of the bucket wheel spline shaft and the spline hollow shaft reducer, ensuring stable and safe production. 2. The structure is simple, the parts are easy to process and manufacture, convenient for inspection, and safe and reliable.

[0009] The embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
