Abstract

The invention discloses a split type MC nylon wheel in the technical field of roller wheels used for elevators and lifting machinery, which comprises a wheel core made of MC nylon and a metal outer rim arranged outside the wheel core. A mounting hole and a key groove are arranged in the center of the wheel core; two steps which are mutually matched are arranged between the outer edge of the wheel core and the inner edge of the metal outer rim; and the two steps are mutually connected through a plurality of bolts which are parallel to an axis. When in use, the device is installed on a rotating shaft through the mounting hole and the key groove, thus being capable of transmitting torque, and the wheel core is made of the nylon material which has sufficient elasticity and strength and good impact resistance, thus being capable of transmitting larger torque; the metal outer rim is a wearing part and can be replaced solely after being worn, while the wheel core can be repeatedly used, and the device ensures that the overall weight of the roller wheel is reduced, the production cost is reduced, the waste of resources is reduced, parts of devices can be reused, thus having environmental effect. The device can be securely applied to the elevators and the lifting machinery.

Description

Split type MC nylon wheel

Technical field

The present invention relates to a kind of wheel body of using in the mechanical fields such as elevator, elevator machinery.

Background technology

In elevator, elevator machinery industry, a large amount of employing single-piece metallic sheaves are driving wheel, this pulley is made into integration by metallic material, its Heavy Weight, cost height, can only integral replacing after the damage, consider the safety of other load carriers, the steel rope that matches, supporting mechanism all should correspondingly increase, overstriking, and this makes the cost of integral device significantly rise.

Summary of the invention

The object of the invention is to design a kind of energy cost-cutting, environmental protection, the split type MC nylon wheel that part body utilizes again.

The object of the present invention is achieved like this: split type MC nylon wheel, comprise the core wheel and the outer metal outer ring that is provided with of core wheel of making by MC nylon, the core wheel center is provided with mounting hole and keyway, be provided with the step that cooperatively interacts between the inner edge of core wheel outer rim and metal outer ring, be connected through screw some and that axis parallels between two steps.

When this device uses, this device is installed in the rotating shaft by mounting hole and keyway, can transfer torque, core wheel is made by nylon material, has enough elasticity and intensity, and its Dent resistance is good, can transmit than high pulling torque; The metal outer ring is a consumable accessory, can change separately after it damages, and core wheel can repeated multiple times use, and this device makes that the overall weight of roller reduces, manufacturing cost descends, and has reduced the wasting of resources, and part body can utilize again, has environment protecting.This device can be used safely on elevator and the elevator machinery.

Description of drawings

Fig. 1 is a structural representation of the present invention;

Fig. 2 is the right elevation of Fig. 1.

Wherein, 1 metal outer ring, 2 screws, 3 core wheels, 4 mounting holes, 5 keyways, 101,301 steps.

The specific embodiment

As Fig. 1 and 2, be split type MC nylon wheel, comprise the core wheel 3 and the core wheel 3 outer metal outer rings 1 that are provided with of making by MC nylon, core wheel 3 centers are provided with mounting hole 4 and keyway 5, be provided with between the inner edge of the outer rim of core wheel 3 and metal outer ring 1 between the step 101 that cooperatively interacts and 301, two

steps

101 and 301 and be connected through screw 2 some and that axis parallels.

This roller has following superiority:

But 1, roller local replacing, than bulk metal roller cost-saved 40%～50%;

2, adopting Split MC nylon wheel only need change metal outer ring (consumable accessory) gets final product; Can reduce The workload of install changing;

3, in light weight, assembling, transportation, replacing are conveniently;

4, environmental protection, hub portion can corrosions, oxidation, prolonged service life.

Claims

1, split type MC nylon wheel, it is characterized in that: comprise the core wheel and the outer metal outer ring that is provided with of core wheel of making by MC nylon, the core wheel center is provided with mounting hole and keyway, be provided with the step that cooperatively interacts between the Inner edge of core wheel outer rim and metal outer ring, be connected through screw some and that axis parallels between two steps.
