Abstract
The invention provides a novel shaft end locking structure for engineering machinery planetary gearboxes, which comprises an output shaft, an output flange, a washer and a blocking nut.The arc-shaped groove of the thread portion at the shaft end of the output shaft and the periphery of the blocking nut are subject to riveting punch at the groove part and are matched with each other to be used, thereby ensuring the reliability of the shaft end locking structure.The washer and the blocking nut are screwed into the thread portion of the shaft end after the installation of the output flange and the output shaft by the engaged spline.After being tightened to a predetermined torque, the locking nut is subject to riveting punch at the groove part to enhance the anti-rotation effect.Meanwhile, the nut can not rotate around the axis of the output shaft, so that the retreat of the nut is avoided.The fastening and anti-rotation capability can be improved by regulating the valve of the torque of the blocking nut and the depth of the riveting punch.By adopting the above structure of the utility model, the operation program is simplified, the work strength is reduced and the assembly quality and efficiency is improved.
Description
Technical field
The utility model relates to a kind of novel axle head locking mechanism that is applied on the engineering machinery planetary transmission.
Background technique
At present, the locking mechanism of engineering machinery planetary transmission output shaft axle head generally is: by cover plate, the combined type anti-loose structure that flange locking plate and clamping bolt are formed, clamping bolt is very easily loosening and cause its fracture under the vibratory impulse operating mode, cause simultaneously to produce abnormal sound in the working procedure, need often to change clamping bolt, output shaft and the output flange that damages; The tapped hole that clamping bolt is installed is positioned on the end face of output shaft; Locking and the anti-rotation of clamping bolt is to realize by encasing bolt mode in front behind the locking plate flange.The programmed sequence of operations of locking plate flange is loaded down with trivial details and be difficult for standard, workload is big.
Summary of the invention
The purpose of this utility model is: a kind of novel axle head locking mechanism on the gearbox that can not become flexible under the vibratory impulse operating mode is provided, fundamentally solved the loosening easily and fracture of clamping bolt, the clamping bolt screw-down torque reduces or the caused fault that lost efficacy gradually.
The purpose of this utility model is achieved in that by output shaft, output flange, packing ring and locking nut to be formed, dash the supporting use in back by the circular arc type groove of output shaft axle head helical thread portion and the circle edge of locking nut in the groove riveting, guarantee the reliability of axle head locking mechanism.After output flange and output shaft are installed by mesh splines, helical thread portion with packing ring and locking nut screw-in axle head, carrying out riveting at groove at locking nut screwing after the regulation moment dashes to strengthen the anti-rotation effect, guarantee that nut can not cause that it axially retreats around the output shaft rotational, its fastening and anti-rotation ability are that size and the riveting by locking nut moment improves towards the degree of depth.
Because the utility model adopts said structure, improved the stability and the reliability of gearbox torque transmission capacity, simplified programmed sequence of operations, alleviated working strength.

Embodiment
Embodiment: form by output shaft 1, output flange 2, packing ring 3 and locking nut 4.Among Fig. 1, output flange 2 inserts on the mesh splines of output shaft 1, subsequently packing ring 3 and locking nut 4 is screwed in the helical thread portion of output shaft 1 axle head.Among Fig. 2, at output shaft 1 axle head helical thread portion, mill two circular arc type grooves that do not influence the output shaft bulk strength along axial direction.After locking nut 4 tightens to regulation moment, dash supporting use to the appropriate depth, guarantee the locking effect under the vibratory impulse operating mode with the circular arc type groove riveting of output shaft 1 axle head helical thread portion.The utility model assembling is simple, and the axle head locking mechanism is reliably effective.
