Abstract
The utility model relates to a rigid shaft connecting structure used for a water pump shaft, which comprises a pump shaft and a driving shaft. The utility model is characterized in that the shaft center position of the pump shaft is provided with an inner counterbore, and a gap which is along the shaft direction is arranged on a lateral surface of the pump shaft. The gap penetrates the inner counterbore, the driving shaft is arranged in the inner counterbore and a locking ring is arranged outside the pump shaft. The locking ring forms a C shape, and two ends are connected by locking screws. The utility model has the advantage of the reliability of the rigid connection of the pump shaft and the driving shaft is improved, and simultaneously the assembly and the disassembly among shafts are convenient.
Description
Technical field
The utility model relates to a kind of linkage structure, particularly a kind of stiff shaft linkage structure that is used for water pump spindle.
Background technique
The connection of at present domestic traditional stiff shaft, a kind of is after adopting pump shaft and live axle transition fit, the structure of locating with pin; This shortcoming is that pump shaft and live axle are tighter owing to cooperating, so dismounting is difficult, and axial dimension is controlled than difficult.Another structure is to adopt the structure of rigidity folder shell shaft joint; Though the dismounting of this structure is comparatively convenient, but owing to increased the connecting link of the centre of shaft joint, add processing and factor such as assembling, 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.
Summary of the invention
The purpose of this utility model is the existing the problems referred to above of connection that solve stiff shaft in the prior art, and a kind of stiff shaft linkage structure that is used for water pump spindle that overcomes above-mentioned shortcoming is provided.A kind of stiff shaft linkage structure that is used for water pump spindle of the utility model design, comprise pump shaft, live axle, it is characterized in that: there is counterbore at the place, axle center of pump shaft, one vertically slit is arranged on a side of pump shaft, the slit connects to interior counterbore, in interior counterbore live axle is arranged, and a locking ring is arranged outside pump shaft, locking ring is a C font, and its two ends have lock screw to connect.The utility model has the advantages that and improve pump shaft and the rigidly connected reliability of live axle, installation and dismounting between the convenient simultaneously axle.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing 1 is a structural representation of the present utility model,
Accompanying drawing 2 is the AA cross-sectional view of Fig. 1 of the present utility model,
Embodiment
Comprise pump shaft 1, live axle 2 among the figure, it is characterized in that: there is counterbore 3 at the place, axle center of pump shaft 1, one vertically slit 4 is arranged on a side of pump shaft 1, slit 4 connects to interior counterbore 3, in interior counterbore 3, live axle 2 is arranged, one locking ring 5 is arranged outside pump shaft 1, and locking ring 5 is a C font, and its two ends have lock screw 6 to connect.When pump shaft 1 with after live axle 2 is connected, adjust the shaft core position of pump shaft 1 and live axle 2 this moment, realize the axially accurate location of pump shaft 1 and live axle 2.Adjust the position of locking ring 5 in the taper fit of pump shaft 1 this moment, makes locking ring 5 near at the shaft shoulder place of pump shaft 1, with lock screw 6 rope strengthening ring 5 is locked on the live axle 2 together with pump shaft 1 at last.
