Abstract

The invention discloses a shaft connecting device for a long shaft, relates to the field of shaft connection devices, and aims to enable the operation manner of the long shaft to become safer. The device adopts the scheme that a support plate is connected to the middle part of the upper surface of a base; side plates are connected to the two sides of the bottom of a lower buckling plate; the inner side of each of the lower buckling plate and an upper buckling plate is semi-circular ring-shaped; the lower buckling plate and the upper buckling plate are connected and fixed through screw holes and screws formed and arranged on the outer sides of the upper buckling plate and the lower buckling plate; bearing lower grooves are positioned in the two ends of the semi-circular ring-shaped side surface of the lower buckling plate; bearing upper grooves are positioned in the two ends of the semi-circular ring-shaped side surface of the upper buckling plate; a cross-shaped concave groove is formed in the end face of a front shaft, while a cross-shaped convex part is arranged on the end face of a rear shaft. According to the invention, the separated buckled type bearing grooves are matched with bearings, and the front shaft and the rear shaft which are in a convex-concave matching structure are effectively connected for operation, so that the mechanical operation strength of the long shaft is reduced.

Description

A kind of major axis coupling device

Technical field

The present invention relates to common coupling device field, particularly relate to a kind of major axis coupling device.

Background technique

In the production operation process of factory floor, some axle class bar is long, and during major axis running, axle middle section position can bear comparatively big bang and pulling force, and long-term running can exist potential safety hazard.

Summary of the invention

The present invention will solve above technical problem, provides a kind of major axis coupling device, makes the drive manner of major axis become safer.

For solving the problems of the technologies described above, the present invention is achieved by the following technical solutions:

The invention provides a kind of major axis coupling device, comprise base, dunnage, side plate, lower plywood, upper plywood, groove under bearing, groove on bearing, bearer ring, front axle, rear axle, dunnage is connected in the middle part of base upper surface, side plate is connected to the both sides bottom lower plywood, lower plywood, the inner side of upper plywood is semi-circular shape, lower plywood and upper plywood are connected to a fixed by the screw screw be arranged on outside plywood, under bearing, slot is in the two ends of the annulus side surface of lower plywood, on bearing, slot is in the two ends of the annulus side surface of upper plywood, the end face of front axle is provided with cross recess, the end face of rear axle is provided with cross projection.

Wherein, the position dimension drive fit of the cross recess of front axial end and the cross projection of rear axial end, the size drive fit of groove and bearer ring on groove, bearing under bearing, the matching size of the size in the annulus chamber formed inside upper plywood, lower plywood and front axle, rear axle closes.

Compared with prior art, the invention has the beneficial effects as follows: the present invention adopts coordinating of the bearing groove of separator card button and bearing, the antero posterior axis with concave-convex fit structure is effectively connected running, reduces the machine operation intensity of major axis.
