Abstract

The utility model discloses a split type MC nylon driven wheel in the technical field of rollers used in elevators and lifting appliances. The split type MC nylon driven wheel comprises a wheel core and a metal outer ring, wherein the wheel core is made of MC nylon, the metal outer ring is arranged outside the wheel core, the center of the wheel core is equipped with a supporting bearing, pluralities of projections and grooves which are mutually engaged are arranged between the outer edge of the wheel core and the inner edge of the metal outer ring, two sides of a combination portion of each projection and each groove are respectively equipped with a gland, and the two glands are connected via a bolt penetrating through the wheel core. During usage, the split type MC nylon driven wheel is arranged on a rotating shaft through a bearing and is utilized as a driven wheel, the wheel core which is made of nylon materials has enough elasticity and strength, is fine in impact resistance and is not easy to be damaged, the metal outer ring is a quick-wear part and can be independently replaced after being damaged, and the wheel core can be reused. By aid of the split structural MC nylon wheel, rollers are light in weight and low in cost, and portions of mechanisms can be reused, thereby achieving environment-friendly effect. The split structural MC nylon wheel can be used for elevators and lifting appliances safely, and can be manufactured into geneva wheels, rollers, gears and the like.

Description

Split type MC nylon flower wheel

Technical field

The utility model relates to a kind of roller that uses 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 flower 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.

The utility model content

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

The purpose of this utility model is achieved in that split type MC nylon flower 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 block bearing, be provided with some projectioies that cooperatively interact and groove between the inner edge of core wheel outer rim and metal outer ring, the binding site both sides of described projection and groove are respectively equipped with gland, and the bolt of the core wheel that wore long between two glands is connected.

When this device uses, this device is installed in the rotating shaft, can be used as flower wheel and use by bearing; Core wheel is made by nylon material, has enough elasticity and intensity, and its Dent resistance is good, and is not fragile; The metal outer ring is a consumable accessory, and it can be changed separately after damaging, 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 in to can be made into sheave, roller, gear etc. on elevator and the elevator machinery.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the left view of Fig. 1.

Wherein, 1 metal outer ring, 101 grooves, 2 glands, 3 bolts, 4 core wheels, 5 block bearings.

The specific embodiment

As Fig. 1 and 2, be split type MC nylon flower wheel, comprise the core wheel 4 and the core wheel 4 outer metal outer rings 1 that are provided with of making by MC nylon, core wheel 4 centers are provided with block bearing 5, be provided with some projectioies that cooperatively interact and groove 101 between the inner edge of the outer rim of core wheel 4 and metal outer ring 1, groove 101 is arranged on inboard, metal outer ring, and the bolt 3 that the binding site both sides of projection and groove are respectively equipped with the core wheel 4 that wore long between gland 2, two glands 2 is connected.

This driven pulley can be made sheave, roller and gear etc., has following superiority:

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

When 2, changing, only need to change metal outer ring (consumable accessory) and get final product; Reduced the workload of changing has been installed;

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 flower 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 block bearing, be provided with some projectioies that cooperatively interact and groove between the Inner edge of core wheel outer rim and metal outer ring, the binding site both sides of described projection and groove are respectively equipped with gland, and the bolt of the core wheel that wore long between two glands is connected.
