Abstract
The utility model discloses a fixing structure for a spline crank arm. The fixing structure comprises an open slot which extends along the radial direction of a spline hole arranged on the spline crank arm, flangings arranged on the periphery of the spline hole in a protruding way are arranged at the two sides of the open slot, bolts for fastening the two flangings to contract the open slot are arranged on the flangings in a penetrating way, and a gasket is arranged in the open slot. For the fixing structure for the spline crank arm, the open slot is arranged on the existing spline crank arm, and the gasket is arranged in the open slot, so that the tight matching between a spline shaft and the spline crank arm is ensured, and the fixing structure for the spline crank arm is easy to assemble and disassemble and cannot generate transmission loss; and the loosing phenomenon between the spline shaft and the spline crank is avoided, so that the safety in use of the spline crank arm is ensured.
Description
Technical field
The utility model relates to the gearing technical field, is specifically related to a kind of spline connecting lever fixed structure.
Background technique
As everyone knows, traditional splined shaft cooperates with the spline connecting lever and has following several kinds of shortcomings: 1, have the probability distribution problem of machining accuracy, when drawing spline and rolling splined shaft; Because the wearing and tearing of cutter; Can not guarantee that all splined shafts and connecting lever all are drive fits, perhaps can be tight, perhaps can be loose; The cooperation of tension will cause being difficult to dismounting, and the cooperation of pine can let transmission produce unnecessary transmission loss excessively; 2, inconvenient installation is because general splined shaft and spline connecting lever all are Spielpassung or interference fit, so all very difficult when installation and removal; 3, no locking self-tightening device, between splined shaft and the connecting lever spline if Spielpassung or the transition fit that causes because of processing problems after the long-time operation campaign, can cause splined shaft and spline connecting lever to get loose.
The model utility content
The purpose of the utility model is to provide a kind of spline connecting lever fixed structure.
In order to realize above purpose; The technological scheme that the utility model adopted is: a kind of spline connecting lever fixed structure; Comprise along the opening slot that radially extends that is arranged at the splined hole on the spline connecting lever; The both sides of said opening slot are provided with and are convexly set in peripheral the turning edge of splined hole, are equipped with on turning edge to be used for fastening two and to turn edge to fold the bolt of opening slot, are provided with pad in the said opening slot.
Further, said pad and opening slot Spielpassung.
Said pad is sheathed on the bolt.
The spline connecting lever fixed structure that the utility model provides is through being provided with opening slot on existing spline connecting lever; Make the spline connecting lever have the certain elastic deformation surplus; Fold the opening slot of spline connecting lever then through bolton, reach the purpose of fastening pressing splined shaft.The spline connecting lever fixed structure that the utility model provides has guaranteed the drive fit of splined shaft and spline connecting lever; Too tight or too loose phenomenon can not appear; Easy disassembling and can not produce transmission loss, and after the long-time operation campaign, be not easy to occur the phenomenon that gets loose of splined shaft and spline connecting lever.The problem that gets loose does not appear in order further to guarantee to be used for the fastening bolt that folds spline connecting lever opening slot; In opening slot, be provided with pad; Obviously reduced the deformation space of spline connecting lever when driving the splined shaft motion; The spline connecting lever is difficult for producing vibration at the opening slot place when driving the splined shaft motion, thereby has solved the problem that bolt gets loose, and has guaranteed the safe handling of spline connecting lever.
Description of drawings
A kind of embodiment's that Fig. 1 provides for the utility model structural representation.
Embodiment
Embodiment
As shown in Figure 1; A kind of spline connecting lever fixed structure that present embodiment provides; Comprise along the opening slot 6 that radially extends that is arranged at the splined hole 2 on the spline connecting lever 1; The both sides of opening slot 6 be provided be convexly set in splined hole 2 peripheral turn edge 7, turning edge to be equipped with on 7 is used for fastening two 7 the bolts 3 to fold opening slot 6 that turn edge, and is provided with pad 5 in the opening slot 6.Pad 5 is sheathed on the bolt 3, pad 5 and opening slot 6 Spielpassung.
