Abstract

The utility model discloses a novel wheel ring and hub device of a central chain elevator, relating to the technical field of mechanical improvement in the building industry. The novel wheel ring and hub device comprises bolts, a wheel ring, a hub and keys, wherein the keys are arranged between the wheel ring and the hub. According to the utility model, the torque force between the wheel ring and the hub is transferred without the need of the bolts by increasing the keys for transferring the torque force, the bolts only play a role of connecting the wheel ring and the hub; and because the torque is transferred by the keys, the accident that a chain wheel is damaged in avoided, and the safe operation of the whole equipment of the central chain elevator is ensured.

Description

A kind of later-model central chain gig torus and hub unit

Technical field:

The utility model relates to building material industry and uses the mechanical modification technical field, is specifically related to a kind of later-model central chain gig torus and hub unit.

Background technology:

The chain speed of central authorities' chain gig can reach 1.86m/s the soonest, and the operational throughput maximum can reach 1800m ³/ h, and the head transportation sprocket is the core component of central chain gig, if sprocket wheel goes wrong, gig just can not move and take place safety misadventure so.

For the ease of the fastest; Change sprocket wheel under the simplest prerequisite, central chain gig head transportation sprocket is designed to split type sprocket wheel, and (like Fig. 1) is made up of torus 3, wheel hub 4, bolt of rear end plate 2 parts in sprocket design in the past; This kind structure in use for some time; Bolt 2 occurs loosening, thereby causes torus 3 and wheel hub 4 to occur skidding and the decentraction running, makes the equipment generation with safety misadventure of can't turning round.

The utility model content:

The purpose of the utility model provides a kind of later-model central chain gig torus and hub unit, and it can solve existing problem in the background technology, the accident that sprocket wheel damages can not occur, and makes whole equipment of central chain gig can safe operation.

In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it comprises bolt 2, torus 3, wheel hub 4; It also comprises key 1, and key 1 is arranged between torus 3 and the wheel hub 4.

The utility model is through increasing the key 1 that transmits torsion; Making torsion between torus 3 and the wheel hub 4 need not bolt 2 transmits; 2 on bolt works to connect torus and wheel hub; Transfer torque transmits through key 1, the accident that makes sprocket wheel can not occur damaging, thus guaranteed the safe operation of whole equipment of central chain gig.

The utlity model has following beneficial effect: the accident that sprocket wheel damages can not occur, make whole equipment of central chain gig can safe operation.

Description of drawings:

Fig. 1 is the prior art constructions scheme drawing;

Fig. 2 is the structural representation of the utility model;

Fig. 3 is that the A-A of Fig. 2 is to cutaway view.

The specific embodiment:

Referring to Fig. 2-3, this specific embodiment adopts following technical scheme: it comprises bolt 2, torus 3, wheel hub 4; It also comprises key 1, and key 1 is arranged between torus 3 and the wheel hub 4.

This specific embodiment is through increasing the key 1 that transmits torsion; Making torsion between torus 3 and the wheel hub 4 need not bolt 2 transmits; 2 on bolt works to connect torus and wheel hub; Transfer torque transmits through key 1, the accident that makes sprocket wheel can not occur damaging, thus guaranteed the safe operation of whole equipment of central chain gig.

The accident that sprocket wheel damages can not appear in this specific embodiment, makes whole equipment of central chain gig can safe operation.

Claims

1. later-model central chain gig torus and hub unit, it comprises bolt (2), torus (3), wheel hub (4); It is characterized in that it also comprises key (1), key (1) is arranged between torus (3) and the wheel hub (4).
