Abstract

The utility model provides a connection expansion sleeve which is fast assembled and disassembled by a pressing ring plate. The connection expansion sleeve is composed of an inner cone sleeve, an outer cone sleeve, a pressing ring plate and a set of screws. A contraction expansion slot is arranged in the wall of the inner cone sleeve, an extension expansion slot is arranged in the wall of the outer cone sleeve, and a disassembly screw hole and an assembly through hole are arranged in a convex ring plate. The screws are tightly screwed to enable the pressing ring plate to push the outer cone sleeve to be wedged in a concave ring hole of a wheel hub, a transmission shaft is tightly hooped by the contraction deformation of the inner cone sleeve, the concave ring hole of the wheel hub is tightly expanded by the extension deformation of the outer cone sleeve simultaneously, a wheel can be fixed to a shaft, and a work task of transference motion and torque can be completed. The utility model has the advantages of simple structure, convenient operation, labor saving and time saving.

Description

A kind of connection swelling cover that loads and unloads fast by the pressure ring plate
Technical field:
The utility model relates to mechanical technology, the coupling of particularly a kind of coupling shaft and wheel, specifically a kind of connection swelling cover that is loaded and unloaded fast by the pressure ring plate.
Background technique:
In the common mechanical transmission, axle is to be fixed together by key with the wheel (for example belt pulley, gear, sprocket wheel etc.) that is enclosed within on the axle, realize the purpose of transmitting movement and moment of torsion,, wheel can be fixedly linked in well axle and go up and together rotate with axle because the key ways of connecting is simple in structure.But traditional key Placement exists the defective of dismounting inconvenience, and the installation or removal wheel mostly is that the mode that adopts manpower to beat bump is carried out, and it is time-consuming to require great effort, troublesome poeration.In addition, adopt the key ways of connecting also must on the wheel hub of axle and wheel, set out keyway, not only weakened the mechanical strength of axle and wheel hub, and can produce stress at the position that axle and wheel hub are offered keyway and concentrate, occur crackle, crack even opening easily at the keyway place of axle or wheel hub and can directly cause mechanical failure, have a strong impact on the proper functioning life-span of machine.
Summary of the invention:
The utility model is to propose a kind of connection swelling cover that is loaded and unloaded fast by the pressure ring plate on the basis of existing technology; it not be used on transmission shaft and the wheel hub and offers keyway; the mechanical strength of harmless part itself; unstressed concentrating; can guarantee the installation precision of machinery; it is very convenient to manipulate; laborsaving saving time; it is achieved by the following technical solution: it is mainly by the inner conical drogue that cooperatively interacts; external conical sleeve; pressure ring plate and one group of screw constitute; done on the wall of inner conical drogue and shunk the swelling seam; done expansion swelling seam on the wall of external conical sleeve; do on the bulge loop plate of pressure ring plate assembling and dismantling unload screw and with wheel hub on the assembling done join the assembling through hole that screw matches; when installing and using: inner conical drogue is set on the transmission shaft; become the external conical sleeve of cone match to be installed in the scrobicular ring hole of wheel hub with inner conical drogue; again the pressure ring sleeve-board is loaded on transmission shaft and withstands external conical sleeve; inner conical drogue props up the bottom surface in the scrobicular ring hole of wheel hub; insert the assembling through hole of doing on the bulge loop plate and screw in the assembling screw of doing on the wheel hub to become to be threaded with one group of screw; in the process of tightening screw gradually; pressure ring plate pushing tow external conical sleeve makes in the scrobicular ring hole of its wedging wheel hub; do the inner conical drogue that shrinks the swelling seam and be squeezed the radially inside contraction deformation of power the transmission shaft banding; the external conical sleeve of doing expansion swelling seam simultaneously radially expands outwardly the scrobicular ring hole swelling of distortion with wheel hub; can firmly be fixed in wheel on the transmission shaft; during dismounting: unscrew and withdraw from screw; screw in again and do assembling and dismantling on the bulge loop plate of pressure ring plate and unload in the screw and when being torqued-up to the end face that withstands wheel hub gradually; can withdraw from the pressure ring plate in the scrobicular ring hole of wheel hub and unclamp external conical sleeve, so far can finish from the operation of transmission shaft dismounting wheel.
Description of drawings:
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is the A-A view of Fig. 1,
Fig. 3 is the B-B view of Fig. 1.
Embodiment:
A kind of connection swelling cover that loads and unloads fast by the pressure ring plate that the utility model proposed, it is mainly by the inner conical drogue 1 that cooperatively interacts, external conical sleeve 2, pressure ring plate 7 and one group of screw 6 constitute, done on the wall of inner conical drogue 1 and shunk swelling seam 11, done expansion swelling seam 8 on the wall of external conical sleeve 2, do on the bulge loop plate 13 of pressure ring plate 7 assembling and dismantling unload screw 14 and with wheel hub 3 on the assembling done join the assembling through hole 5 that screw 4 matches, it is to use like this: when installing and using, inner conical drogue 1 is set on the transmission shaft 12, in the external conical sleeve 2 of 1 one-tenth cone match of inner conical drogue is installed on the scrobicular ring hole 10 of wheel hub 3, pressure ring plate 7 is set in transmission shaft 12 and withstands external conical sleeve 2, inner conical drogue 1 props up the bottom surface in the scrobicular ring hole 10 of wheel hub 3, the assembling through hole of making on the bulge loop plate 13 of one group of screw, 6 insertion pressure ring plates 75 also screws in the assembling screw of doing on the wheel hub 34 to become to be threaded, and tighten the scrobicular ring hole 10 that screw 6 makes pressure ring plate 7 pushing tow external conical sleeves 2 wedging wheel hubs 3 gradually, do the inner conical drogue 1 that shrinks swelling seam 11 and be squeezed radially inwardly contraction deformation transmission shaft 12 bandings, the external conical sleeve 2 of doing expansion swelling seam 8 simultaneously radially expands outwardly scrobicular ring hole 10 swellings of distortion with wheel hub 3, wheel hub 3 firmly can be fixed on the transmission shaft 12, during dismounting: unscrew and withdraw from screw 6, screw in again and do assembling and dismantling on the bulge loop plate 13 of pressure ring plate 7 and unload in the screw 14 and when being torqued-up to the end face 9 that withstands wheel hub 3 gradually, can in the scrobicular ring hole 10 of wheel hub 3, withdraw from pressure ring plate 7, unclamp external conical sleeve 2, can dismantle wheel from transmission shaft 12.The utility model proposed by the pressure ring plate connection swelling cover of loading and unloading fast, had simple in structurely, easy for operation, and laborsaving timesaving advantage can be guaranteed the installation precision of mechanical parts can improve mechanical transmission performance.
