Abstract
The utility model discloses a connecting structure of a drive shaft and a lengthened shaft, belonging to the mechanical connecting structures. As the conventional drive shaft and lengthened shaft are connected through a shaft coupler, low transmission precision and poor coaxiality as well as reliability are caused. The connecting structure of the drive shaft and the lengthened shaft comprises a drive shaft and a lengthened shaft, wherein a counter bore is arranged at the axis of the end part of the lengthened shaft; the wall of the counter bore is provided with a gap; one end of the drive shaft is inserted into the counter bore; and the position at the outer side of the wall of the counter bore, which corresponds to the gap, is tightly locked by a connecting ring. As a customized drive shaft is unnecessary, the connecting structure of the drive shaft and the lengthened shaft, disclosed by the utility model, has the advantages of improving reliability of rigid connection between the drive shaft and the lengthened shaft, being high in assembling precision, improving transmission precision and coaxiality and bringing convenience for installation and detachment.
Description
Technical field
The utility model belongs to mechanical connecting structure, specifically is the linkage structure of a kind of live axle and extension shaft.
Background technique
The customization of live axles such as present motor both domestic and external, diesel engine particularly is the customization of Diesel Driven axle, is quite to bother, and promptly enables customization, and lead time will prolong, cost will increase.
At present domestic and international traditional driving axle is connected with extension shaft; Adopt the linkage structure of rigidity clamping coupling; Though the dismounting of this structure is comparatively convenient,, add factors such as processing and assembling owing to increased the intermediate connecting ring joint of coupling; It is not high to make this structure be prone to transmission accuracy in actual use, causes pump shaft and live axle coaxality difference and reliability poor yet.
The model utility content
The technical problem that the utility model will solve and the technical assignment of proposition be overcome existing live axle and extension shaft through coupling be connected that the transmission accuracy that causes is not high, the defective of coaxality and poor reliability, the linkage structure of a kind of live axle and extension shaft is provided.
For reaching the purpose of the utility model; The live axle of the utility model and the linkage structure of extension shaft comprise live axle, extension shaft; It is characterized in that: the place, axle center, end of said extension shaft establishes counterbore; Offer the slit on the wall of said counterbore, an end of described live axle inserts described counterbore, is locked by connecting ring at the position in the corresponding said slit, the outside of the wall of said counterbore.
As the optimization technique measure, described slit is at least two and be uniformly distributed with in a circumferential direction.
As the optimization technique measure, described connecting ring is formed by connecting through lock screw two semi-rings.Further, stagger in the slit between the slit on the said counterbore wall and said two semi-rings.
The beneficial effect of the utility model is: do not customize live axle, improve live axle and the rigidly connected reliability of extension shaft, assembly precision is high, and transmission accuracy and coaxality are improved, convenient simultaneously the installation and dismounting.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model;
Fig. 2 is that A-A among Fig. 1 is to sectional view;
Label declaration among the figure: 1-live axle, 2-extension shaft, 3-counterbore, the slit on the 4-counterbore wall, 5-connecting ring, 6-semi-ring, the slit between two semi-rings of 7-, 8-lock screw.
Embodiment
Below in conjunction with Figure of description the utility model is further specified.
The live axle of the utility model and the linkage structure of extension shaft; Like Fig. 1, shown in 2; It comprises live axle 1, extension shaft 2, and the place, axle center, end of extension shaft 2 establishes counterbore 3, offers slit 4 on the wall of counterbore 3; One end of live axle 1 inserts counterbore 3, at the position in the corresponding slit 4, the outside (axially offer and be convenient to make) of the wall of counterbore 3 by connecting ring 5 lockings.Especially, the slit on counterbore 3 walls is at least two (being illustrated as 3) and be uniformly distributed with in a circumferential direction.Connecting ring 5 two semi-rings 6 through lock screw 8 be formed by connecting (folder shell-type coupling ring); Stagger in slit 7 between slit 4 on counterbore 3 walls and two semi-rings.The utility model is regarded as linkage structure, through tightening or unclamping lock screw and can realize installing the locking and the dismounting that gets loose.
