Abstract
The invention discloses a novel steel belt for an elevator tractor. The novel steel belt comprises a rubber body (2) in a flat structure, wherein an inner surface (4) in contact with a pulley assembly is arranged on the rubber body (2). The novel steel belt is characterized in that three grooves (6) are uniformly arranged in the inner surface (4) at intervals, and the grooves (6) extend along the length of the rubber body (2). The novel steel belt has the advantages that the structure is simple, and the service life is longer.
Description
Technical field
The present invention relates to a kind of elevator traction machine, relate in particular to a kind of elevator traction machine and use new steel belt.
Background technique
At present; Along with tall building is more and more; Demand to express elevator also increases gradually, and the elevator hoisting that the most of elevator system maker of China offers market goes up and down all to adopt elevator to use wire rope, finds in the long-term back of using; This product in use still has multiple deficiency, and is specific as follows:
1), cause elevator noise when operation bigger because wire rope in use is prone to swing;
2) for reducing the wearing and tearing of wire rope, on wire rope, scribble lubricant grease usually, in use amplitude of fluctuation is bigger owing to wire rope, causes the lubricant grease in the wire rope to spill, and pollutes machine room;
3) wire rope can produce disconnected strand of fracture of wire after using a period of time, makes elevator shake and shutdown, causes the increase of elevator maintenance cost.
Because the existence of above-mentioned deficiency; Increasing elevator hoisting goes up and down to begin to adopt steel band to replace the effect of wire rope; Yet because steel band has the body structure of rubber; And rubber long-term use wearing and tearing after, be easy to generate slight crack under the external force extruding receiving, so can have a strong impact on the use birthday noodle of steel band.
Summary of the invention
Technical problem to be solved by this invention provides a kind of elevator traction machine simple in structure, that working life is long and uses new steel belt.
For solving the problems of the technologies described above; The technological scheme that the present invention adopted is: a kind of elevator traction machine is used new steel belt; The rubber body that comprises flat structure; Have on the said rubber body and the contacted internal surface of pulley assembly, evenly spacedly on the said internal surface be provided with three grooves, said groove extends along the length of said rubber body.
Said three grooves lay respectively at the edge and the intermediate portion of said internal surface.
The cross section of said groove is rectangle, semicircle or trigonometric form.
Compared with prior art, beneficial effect of the present invention is:
Because elevator traction machine of the present invention is provided with three grooves with the internal surface of new steel belt rubber body; After rubber body receives the external force extruding; Groove can effectively be alleviated the extruding force on the steel band; Produce slight crack so can prevent steel band, so the present invention is simple in structure, working life is longer.
Description of drawings
Specify the present invention below in conjunction with accompanying drawing and mode of execution:
Fig. 1 is a structural representation of the present invention.
Among the figure: rubber body 2, internal surface 4, groove 6.
Embodiment
As shown in Figure 1, a kind of elevator traction machine of the present invention is used new steel belt, comprises the rubber body 2 of flat structure; Have on this rubber body 2 and the contacted internal surface 4 of pulley assembly; Specialization of the present invention is: evenly spacedly on the internal surface 4 be provided with three grooves 6, this groove 6 extends along the length of rubber body 2, after rubber body 2 receives the external force extruding; Groove 6 can effectively be alleviated the extruding force on the steel band, produces slight crack so can prevent steel band.
In actual the use, three grooves 6 lay respectively at the edge and the intermediate portion of internal surface 4, and the cross section of groove 6 is rectangle, semicircle or trigonometric form.
In sum, the present invention is simple in structure, and working life is longer.
The above is merely preferred embodiments of the present invention; Protection scope of the present invention is not exceeded with above-mentioned mode of execution; As long as the equivalence that those of ordinary skills do according to disclosed content is modified or changed, all should include in the protection domain of putting down in writing in claims.
Claims (3)
1. an elevator traction machine is used new steel belt; The rubber body (2) that comprises flat structure; Have on the said rubber body (2) and the contacted internal surface of pulley assembly (4); It is characterized in that: said internal surface (4) is gone up evenly spaced three grooves (6) that are provided with, and said groove (6) extends along the length of said rubber body (2).
2. elevator traction machine according to claim 1 is used new steel belt, it is characterized in that: said three grooves (6) lay respectively at the edge and the intermediate portion of said internal surface (4).
3. elevator traction machine according to claim 1 and 2 is used new steel belt, it is characterized in that: the cross section of said groove (6) is rectangle, semicircle or trigonometric form.
