Abstract
The utility model relates to an expanding coupling sleeve for a bar cutter, and belongs to a keyless drive coupler for mechanical equipment. The expanding coupling sleeve is mainly used for solving the technical problems of poor heavy load stress, uneven stress and poor centering accuracy of the existing expanding coupling sleeve. In order to solve the technical problem, the adopted technical scheme is as follows: the expanding coupling sleeve for the bar cutter comprises a top ring, two outer rings, two inner rings and a bottom ring, wherein the two inner rings form an inner connecting sleeve in a back-to-back manner; the two outer rings are respectively arranged at the sides of the two inner rings to form front and rear annular taper cavities; the top ring and the bottom ring are respectively arranged inside the two annular taper cavities; and the top ring, the two outer rings, the two inner rings and the bottom ring are arranged together through bolts. The expanding coupling sleeve for the bar cutter has the advantages of being accurate to position, convenient to load and unload, and easy to operate, and can bear heavy load; and the connection of thin-wall parts is even in stress.
Description
Technical field
The utility model relates to a kind of bar shears expansion coupling sleeve, and it belongs to a kind of machinery and uses without key transmission coupling piece.
Background technique
Expansion coupling sleeve is a kind of transmission connecting piece, and it can replace the connection effect of singly-bound and spline, realizes the connection of parts (as gear, flywheel, belt pulley etc.) and axle, in order to transfer charge.The expansion coupling sleeve majority that uses now is single cone match expansion set, mainly consisted of by socket head screw, front side ring and rear side ring, although the expansion set of this structure is simple in structure, because it is single cone match expansion set, exist the poor shortcoming of unbalance stress and accuracy of alignment.
Summary of the invention
The purpose of this utility model is to solve stressed poor, the unbalance stress of heavy load that existing expansion coupling sleeve exists and the poor technical problem of accuracy of alignment, provides that a kind of stressed all even accuracy of alignments are good, the bar shears expansion coupling sleeve of easy accessibility.
The utility model is to solve the problems of the technologies described above the technological scheme that adopts to be: the bar shears expansion coupling sleeve, it comprises that in apical ring, two outer shrouds, two, ring and base ring form, wherein: connecting sleeve in two, ring consists of back-to-back, the side that two outer shrouds are located at respectively ring in two forms former and later two ring-type conical cavities, and apical ring and base ring are located at respectively in two ring-type conical cavities and by screw, ring in apical ring, two outer shrouds, two and base ring are installed together.
One end of described interior ring is the loop connecting body, and the cylindrical of the interior ring the other end is conical surface, is provided with several screws on the loop connecting body, axially has an expansion joint at interior ring.
Described outer shroud is ring bodies, and the inner circle of outer shroud is conical surface, axially has an expansion joint at outer shroud.
Described apical ring and base ring are ring bodies, cylindrical and the inner circle of apical ring and base ring are conical surface, the cylindrical conical surface of apical ring and base ring and the conical surface of outer shroud inner circle match, the inner circle conical surface of apical ring and base ring and the conical surface of interior ring cylindrical match, and are provided with several screws and screw hole on apical ring and base ring.
Because the utility model has adopted technique scheme, stressed poor, the unbalance stress of heavy load that existing expansion coupling sleeve exists and the poor technical problem of accuracy of alignment have been solved, and have and install simply, accurate positioning, can bear heavy load, large torque can be satisfied the high precision overloading characteristics such as requirement that are in transmission connection.Therefore, compare with background technique, the utlity model has accurate positioning, can carry heavy load, easy to loading and unloading, easy operating makes the thin-walled component connect the stressed advantage such as evenly.
