Abstract
The utility model discloses a kind of major axis coupling device, relate to common coupling device field.Become safer to make the drive manner of major axis, in the utility model: dunnage is connected in the middle part of base upper surface, side plate is connected to the both sides bottom lower plywood, the inner side of lower plywood, upper plywood is semi-circular shape, lower plywood and upper plywood are connected to a fixed by the screw screw be arranged on outside upper and lower 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, and the end face of rear axle is provided with cross projection.The bearing groove of the utility model employing separator card button and coordinating of bearing, effectively connect running by the antero posterior axis with concave-convex fit structure, reduce the machine operation intensity of major axis.
Description
Technical field
The utility model relates to common coupling device field, particularly relates 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.
Model utility content
The utility model 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 utility model is achieved through the following technical solutions:
The utility model 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 beneficial effects of the utility model are: the bearing groove of the utility model employing separator card button and coordinating of bearing, effectively connect running by the antero posterior axis with concave-convex fit structure, reduce the machine operation intensity of major axis.
