Abstract
The invention discloses an embedded pulley. The embedded pulley comprises a hook, a connection shaft, bolts, a pulley bracket, a double-row ball bearing, a pulley disc, a pressure-resistant roller bearing and a central shaft, wherein one part of the pulley disc is embedded into the pulley bracket, so that the slippage space of a steel wire rope is reduced; the pulley hook is connected to the pulley bracket through the connection shaft; a compressive bearing is arranged inside the connection shaft, so that the hook can rotate flexibly; the pulley bracket is cast by high-strength manganese steel and is assembled by bolts; the pulley disc is embedded into the pulley bracket by using the double-row ball bearing and the roller bearing, so that the flexibility of the pulley is improved. Through the embedded pulley, the slippage problem of the steel wire rope can be effectively solved; the safety of the pulley is improved.
Description
Technical field
The present invention relates to a kind of pulley, be specifically related to a kind of embedded rollers.
Background technique
Pulley is a kind of simple machinery, by forming 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: movable pulley and quiet pulley, and the former is for laborsaving, and the latter is for changing the direction of power.The working principle of pulley is lever principle, belongs to the distortion of lever, belongs to lever class simple and mechanical.With low cost, easy to use due to pulley, pulley is widely used in a lot of industry.As building industry, fishery, transport service etc.Traditional pulley is because of pulley sheave and pulley bracket joint excesssive gap, turbine RPM is too fast, and pulley to be given a shock etc. when rotating and easily to cause wire rope slippage, pulley melts when quick rotation and easily causes pulley to be damaged because of wire rope slippage, What is more causes wire cable rupture, leads to serious accident.The method head it off (patent announcement CN201865599U) using the slippage of U-shaped draw-in groove restriction wire rope is proposed for preventing some company of wire rope slippage.The program decreases the probability of wire rope slippage really to a certain extent, but does not tackle the problem at its root, and the phenomenon of wire rope slippage still happens occasionally.
Summary of the invention
The object of the invention is to solve above-mentioned the deficiencies in the prior art, fundamentally solve wire rope slippage problem.There is provided a kind of novel structure, not easily slippage, long service life, embedded rollers easy to maintenance.
The technological scheme that the present invention solves the employing of its technical problem is:
A kind of embedded rollers, comprises pulley bracket, resistance to compression roller bearing, double-row bearing, bolt, wheel disc, coupling shaft, hook composition.Described pulley bracket adopts the austenitic manganese steel casting of high strength to form, and support is divided into two-part, utilizes bolt to be grouped together by two-part, and support is connected with hook by coupling shaft.
Described pulley sheave uses high-abrasive material to make, the smooth of the edge, pulley sheave is by central shaft, double-row bearing, and resistance to compression roller bearing is connected with pulley bracket, wherein double-row bearing is positioned at pulley shell both sides, and resistance to compression roller bearing is positioned at pulley sheave inside.Double-row bearing increases the flexibility of pulley sheave central shaft, and the design of two groups of bearings makes pulley still can normally work when one group of bearing breaks down, and extends the working life of pulley.
Described pulley sheave edge section embeds pulley bracket, makes the wire rope in pulley sheave groove not have for the gap of slippage, thus to effectively prevent wire rope slippage, increases the Security of pulley.
The invention has the beneficial effects as follows: (1) in use can prevent wire rope slippage effectively; (2) working life of pulley is effectively extended; (3) Safety performance of pulley is effectively increased.
Accompanying drawing explanation
Fig. 1 is overall structure figure of the present invention;
Fig. 2 is profile of the present invention;
In figure: 1, link up with, 2, coupling shaft, 3, bolt, 4, pulley bracket, 5, double-row bearing, 6, pulley sheave, 7, resistance to compression roller bearing 8, central shaft.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail:
As shown in Figure 1 and Figure 2, a kind of embedded rollers of the present invention, comprises (1) hook, (2) coupling shaft, (3) bolt, (4) pulley bracket, (5) double-row 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-part, is grouped together during use by bolt (3); The edge of pulley sheave is embedded in pulley bracket by resistance to compression roller bearing (7) double-row bearing (5) and central shaft (8) by described pulley sheave.
Described resistance to compression ball bearing (7) double-row bearing (5) lays respectively at pulley sheave (6) and pulley bracket (4) both sides, and two groups of bearings increase the flexibility of wheel disc, still can normally work at the situation lower pulley block of any one group of bearing damage.
Described pulley bracket (4) pulley sheave (6) adopts high-strength material to process, and adds the lifting capacity of pulley.
Patent of the present invention effectively can prevent wire rope slippage, extends the working life of pulley, add the Security of pulley in sum.
More than show and describe basic principle of the present invention, major character and advantage.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
