Description

Tape wrap formula shaft coupling

Technical field

The utility model is related to shaft coupling fields, more particularly to a kind of tape wrap formula shaft coupling.

Background technology

Existing shaft coupling can only generally couple rotary type axial workpiece, often the manufacture and installation to two axis coupled More demanding, two coupled axis also require almost the same on section shape and size, it is difficult to it is irregular different to couple some Type axial workpiece, to which application range is restricted.

Utility model content

To solve the above problems, the utility model proposes a kind of tape wrap formula shaft couplings.

The technical solution of the utility model is：

A kind of tape wrap formula shaft coupling, including tie-plate, support plate, coupling bar, tape wrap bar, belt, it is characterized in that：

It is belt grooves in the middle part of the tape wrap bar, tie-plate and support plate are close in both ends respectively, wherein close to support plate One end ladder shaft end has screw thread, support plate to be close to multi-diameter shaft step surface on one side, and another side passes through nut, gasket side with tape wrap bar Formula fastens；

The tie-plate is disc, edge along the circumferential direction there are four or eight through-holes so that tape wrap bar is logical It crosses；

The support plate is in circular ring shape, and middle part in support plate by drive shaft or driven shaft, along the circumferential direction having Four or eight through-holes are used for connecting with tape wrap bar being fixed, and the number of openings is consistent with the through-hole on tie-plate with position；

The coupling bar is hingedly fixed between two tie-plates, with tape wrap bar by standard fasteners；

Drive shaft is connected by belt with four or eight tape wrap bars, and when drive shaft turns, shaft coupling is driven by belt Rotation；Driven shaft is connected by belt with four or eight tape wrap bars, shaft coupling rotation, and driven shaft rotation is driven by belt.

Preferably, described tape wrap bar one end is threaded, and the other end is matched with coupling bar junction middle part with coupling bar The slot of conjunction, both sides are platy structure, have through-hole corresponding with the through-hole of coupling bar among plate, are hingedly coordinated with fixing piece.

Preferably, the coupling bar is plate, and the coupling bar direction installed on the shaft coupling is consistent, coupling bar It is hinged to offset the error of centralization for being coupled axis.

Preferably, the quantity of the tape wrap bar is according to the section shape and size for being coupled axis, with reference to required transmission The quantity of the size and characteristic of movement and torque, appropriate selected tape wrap bar is four or eight.

The technique effect of the utility model：

The tape wrap formula coupler structure is simple, securely and reliably, easy to use, convenient for manufacture, dismounting, carrying, adjustment and dimension Shield can adapt to the opposite position of coupled axis caused by carrying in manufacture, installation, abrasion etc. and work and temperature change Deviation is set, to be effectively improved working condition, additional load is reduced, prevents device from shaking, prolong the service life.

Specific implementation mode

Embodiment one：Referring to Fig. 1-10, a kind of tape wrap formula shaft coupling in figure, including tie-plate, support plate, coupling bar, twine Rod failure, belt, it is characterized in that：

Preferably, the coupling bar is plate, and the coupling bar direction installed on the shaft coupling is consistent, coupling bar The hinged error of centralization for adapting to be coupled axis.

Be hollow in the middle part of support plate, to be placed in drive shaft or driven shaft, drive shaft by belt and above-mentioned left side or The tape wrap bar of right side is connected, and when drive shaft turns, the frictional force generated by belt and belt grooves drives tape wrap bar with driving Shaft rotation is dynamic, to drive tie-plate to rotate, then rotation by coupling bar is transmitted to the tie-plate of another half portion, then driven The tape wrap bar of another half portion rotates, and driven shaft is connected again by belt with the tape wrap bar of another half portion, thus passes through skin The frictional force of band drives driven shaft rotation.
