Abstract

The utility model relates to a plain type directly links axle construction, including directly linking axle and motor shaft, directly link axle one end and set up directly linking the axle sleeve, motor shaft one end clearance is packed into and is directly linked the axle sleeve hole, directly links the joint seam of offering more than the twice, even number equipartition on the axle sleeve along its axial, and the both ends of every joint seam are all through a plurality of locking bolt cross-under locking that set up along the joint seam direction, and the opposite direction of cross-under locking bolt on every two joint seams that directly link the axle sleeve upper center relatively. The structure is simple, the production and the assembly are convenient and fast, and meanwhile, the rigid connection is stable.

Description

Simple direct-connected shaft structure

Technical Field

The utility model relates to an axle construction, a plain type directly links axle construction specifically says so.

Background

When the traditional direct-connected shaft is connected with a motor shaft, interference fit and rigid assembly are usually adopted, the interference magnitude needs to be controlled accurately, when the direct-connected rotary transmission is carried out, if the interference magnitude is too small, the direct-connected shaft is extremely easy to separate and fixedly connect after long-term rotation, great potential safety hazards exist, and if the interference magnitude is too large, great and tedious workload is brought to production, assembly and detachment maintenance.

Disclosure of Invention

The utility model provides a simple structure has simultaneously stablized rigid connection's plain type directly connected axle structure, compromises the convenience of production, assembly.

The utility model adopts the technical proposal that: the utility model provides a simple and easy direct connection axle construction, includes direct axle and motor shaft, its characterized in that: the direct-connection shaft is characterized in that a direct-connection shaft sleeve is arranged at one end of the direct-connection shaft, an inner hole of the direct-connection shaft sleeve is arranged in a clearance mode at one end of a motor shaft, more than two joints with even number are arranged on the direct-connection shaft sleeve along the axial direction of the direct-connection shaft sleeve, two ends of each joint are connected and locked through a plurality of locking bolts arranged along the joint direction in a cross-connection mode, and the directions of the cross-connection locking bolts on every two opposite joints in the center on the direct-connection shaft sleeve are opposite.

Further, the clearance between the inner hole of the direct connection shaft sleeve and the motor shaft is 0.05 mm.

Furthermore, the inner hole of the direct-connection shaft sleeve is matched and spliced with the motor shaft through a key and a key groove.

Furthermore, the keyway sets up directly to link the axle sleeve hole, and set up a plurality of key cooperations outside a plurality of and the motor shaft, a plurality of keyways dislocation joint seam equipartition.

The clearance between the direct-connected shaft hole and the motor shaft is 0.05mm when the utility model is processed, and the corresponding assembly and disassembly are convenient; the locking bolts are locked at a plurality of corresponding joint seams to realize rigid connection of two shafts, and the locking bolts are connected on every two centrosymmetric joint seams in a penetrating manner, so that the connection stability and the service life under long-term rotation operation can be effectively ensured.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a view a-a of fig. 1.

In the figure: the direct-connected shaft comprises a direct-connected shaft 1, a direct-connected shaft sleeve 2, a joint seam 3, a locking bolt 4, a key groove 5, a motor shaft 6 and a key 7.

Detailed Description

The invention is further described below with reference to the following examples and the accompanying drawings.

As shown in figures 1-2, a simple direct-connected shaft structure, a direct-connected shaft sleeve 2 is arranged at one end of a direct-connected shaft 1, a gap is formed in one end of a motor shaft 6, an inner hole of the direct-connected shaft sleeve 2 is arranged in the gap, the gap between the inner hole of the direct-connected shaft sleeve and the motor shaft is 0.05mm, two centrosymmetric joint seams 3 are arranged on the direct-connected shaft sleeve along the axial direction of the direct-connected shaft sleeve, two ends of each joint seam are connected and locked in a penetrating mode through a plurality of locking bolts 4 arranged in the direction of the joint seam, and the directions of the penetrating locking bolts on every two joint seams, opposite to each other in the center, on the direct-connected shaft sleeve are opposite.

In this embodiment, the inner hole of the direct-connection shaft sleeve and the motor shaft are matched and spliced through a key and a key groove. The keyway 5 sets up directly links the axle sleeve hole, and sets up a plurality of outer 7 cooperations of a plurality of keys of a plurality of and motor shaft, a plurality of keyways dislocation joint seam equipartitions.

Claims
