Abstract
The utility model discloses an embedded pulley, constitute including couple, connecting axle, bolt, pulley support, double ball bearing, pulley rim plate, resistance to compression roller bearing, center pin. Partly embedding pulley support of pulley rim plate, the space of having reduced the wire rope slippage, the pulley couple has the resistance to compression bearing through linking axle and pulley leg joint in the connecting axle for the couple can rotate in a flexible way, the pulley support adopts the manganese steel casting of high strength to form to make up together through the bolt, utilize on double ball bearing and roller bearing be embedded into the pulley support with the pulley rim plate, increased the flexibility of pulley. The utility model discloses can effectual solution wire rope slippage problem, increase the security of pulley.
Description
Technical field
The utility model relates to a kind of pulley, is specifically related to a kind of embedded rollers.
Background technology
Pulley is a kind of simple machinery, by being formed around the fluted disk of central axis and the rope (rope, adhesive tape, cable wire, chain etc.) striding across disk. Traditional pulley is divided into two classes: travelling block and quiet pulley, and the former is for laborsaving, and the latter is for changing the direction of power. The principle of work of pulley is lever principle, belongs to the distortion of lever, belongs to lever class simple and mechanical. With low cost due to pulley, it may also be useful to easy, pulley is widely used in a lot of industry. Such as construction industry, fishery, transport trade etc. Traditional pulley is because of pulley sheave and pulley bracket junction excessive clearance, pulley rotating speed is too fast, and pulley is given a shock etc. when rotating and easily causes wireline slippage, pulley melts when twirl and easily causes pulley to be damaged because of wireline slippage, What is more causes wire cable rupture, leads to serious accident. The method head it off (patent announcement CN201865599U) using the restriction wireline slippage of U-shaped card groove is proposed for preventing some company of wireline slippage. The program decreases the probability of wireline slippage really to a certain extent, but does not fundamentally deal with problems, and the phenomenon of wireline slippage still happens occasionally.
Summary of the invention
The purpose of this utility model solves above-mentioned the deficiencies in the prior art, fundamentally solves wireline slippage problem. There is provided a kind of novel structure, not easily slippage, it may also be useful to the life-span is long, embedded rollers easy to maintenance.
The utility model solves the technical scheme of its technical problem employing:
A kind of embedded rollers, comprises pulley bracket, resistance to compression roller bearing, double-row balls bearing, bolt, wheel disc, coupling shaft, hook composition. Described pulley bracket adopts the austenitic manganese steel casting of high strength and becomes, and support is divided into two portions, utilizes bolt to be grouped together by two portions, and support is connected with hook by coupling shaft.
Described pulley sheave uses wear-resisting material to make, the smooth of the edge, pulley sheave is by central shaft, double-row balls bearing, and resistance to compression roller bearing is connected with pulley bracket, wherein double-row balls bearing is positioned at pulley shell both sides, and resistance to compression roller bearing is positioned at pulley sheave inside. Double-row balls bearing increases the handiness of pulley sheave central shaft, the design of two groups of bearings make pulley when one group of bearing bad fall still can normal operation, extend the work-ing life of pulley.
Described pulley sheave edge section embeds pulley bracket so that the wireline in pulley sheave groove does not have for the gap of slippage, thus to effectively prevent wireline slippage, increases the security of pulley.
The beneficial effects of the utility model are: (1) in use can prevent wireline slippage effectively; (2) work-ing life of pulley is effectively extended; (3) safety performance of pulley is effectively increased.
Accompanying drawing explanation
Fig. 1 is one-piece construction figure of the present utility model;
Fig. 2 is side elevational view of the present utility model;
In figure: 1, link up with, 2, coupling shaft, 3, bolt, 4, pulley bracket, 5, double-row balls bearing, 6, pulley sheave, 7, resistance to compression roller bearing 8, central shaft.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
As shown in Figure 1 and Figure 2, a kind of embedded rollers described in the utility model, comprises (1) hook, (2) coupling shaft, (3) bolt, (4) pulley bracket, (5) double-row balls bearing, (6) pulley sheave, (7) resistance to compression roller bearing composition. Described hook (1) is connected with pulley bracket (4) by coupling shaft (2), and there is resistance to compression bearing coupling shaft inside, and hook (1) can around axle 360 degree of flexible rotatings; Described pulley bracket (4) is divided into two portions, it may also be useful to time is grouped together by bolt (3); The edge of pulley sheave is embedded in pulley bracket by described pulley sheave by resistance to compression roller bearing (7) double-row balls bearing (5) and central shaft (8).
Described resistance to compression spot contact bearing (7) double-row balls bearing (5) lays respectively at pulley sheave (6) and pulley bracket (4) both sides, and two groups of bearings increase the handiness of wheel disc, and the situation lower sheave in any one group of bearing damage still can normal operation.
Described pulley bracket (4) pulley sheave (6) adopts high-strength material to process, and adds the weight-lifting ability of pulley.
The utility model patent can prevent wireline slippage, the work-ing life extending pulley, the security that adds pulley effectively in sum.
More than show and describe ultimate principle of the present utility model, main feature and advantage. The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model. The claimed scope of the utility model is defined by appending claims and equivalent thereof.
