Description
Technical Field
The utility model relates to an elevator spare part especially relates to an elevator gyro wheel.
Background
An elevator roller is an accessory with extremely high national standard requirements. Most elevator gyro wheels all are the metal preparation, and metal gyro wheel cost of manufacture is very high, can produce certain noise during the use, and the wearability is also poor, and the spoilage is very high, has some wear-resisting noise reduction's elevator gyro wheels on the existing market, but the mechanism all is more complicated, and spare part is many, often has apron, rivet, base etc to the connected mode is single, damages easily.
In the prior art, an elevator roller (publication number: CN203283990U) discloses an elevator roller, which relates to an elevator door roller. The roller comprises a roller base body, a roller wear-resistant layer, a nylon core ring and a rolling clamping groove, wherein the rolling clamping groove is formed in the outer ring of the roller base body, the roller wear-resistant layer is arranged in the rolling clamping groove, and the nylon core ring is embedded in the inner wall of a shaft hole of the roller base body. The nylon core circle periphery on be provided with the interlock boss, the shaft hole internal perisporium of gyro wheel base member on be provided with the interlock recess, nylon core circle passes through sticky boss recess interlock with gyro wheel base member shaft hole internal perisporium and is connected. And a bearing is embedded in the shaft hole of the roller base body. Among this prior art, the bearing installation is inconvenient, and produces the trouble easily among nylon core circle and gyro wheel base member and the bearing cooperation process, causes the life-span of elevator gyro wheel shorter.
Disclosure of Invention
To the above-mentioned technical problem that exists among the prior art, the utility model provides an elevator gyro wheel, simple structure, wear resistance are good, low noise, longe-lived.
In order to achieve the above purpose, the utility model adopts the technical scheme that: an elevator roller comprises a rolling bearing, an outer ring, a rolling clamping groove and a roller wear-resistant layer, wherein the outer ring is coated on the outer surface of the rolling bearing, the circumferential surface of the outer ring is connected with the rolling clamping groove, and the roller wear-resistant layer is arranged in the rolling clamping groove; and a hole a is formed in one side of the outer ring, the diameter of the hole a is smaller than that of the rolling bearing b, a hole c is formed in the other side of the outer ring, and the diameter of the hole c is larger than that of the rolling bearing b.
Furthermore, the rolling clamping groove is a concave rolling clamping groove.
Furthermore, the roller wear-resistant layer is a concave arc surface.
In order to further enhance the service life of the roller, the roller wear-resistant layer is made of thermoplastic resin.
Furthermore, a plurality of inward protruding bayonets are arranged on the circumference of the opening c.
The utility model discloses following beneficial effect has:
(1) the roller wear-resistant layer can provide wear resistance and reduce rotation noise.
(2) The thermoplastic resin has good toughness and large damage tolerance, and the service life of the roller is prolonged.
(3) The bearing bayonet has simple structure, does not need an end cover or a retainer ring, is not easy to damage and has long service life.
Drawings
Fig. 1 is a front cross-sectional view of an elevator roller according to an embodiment of the present invention.
Fig. 2 is a side cross-sectional view of the elevator roller of the embodiment of the present invention.
In the figure, 1 is a rolling bearing, 2 is an outer ring, 3 is a rolling clamping groove, 4 is a wear-resistant layer, and 5 is a bayonet.
Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following embodiments and accompanying drawings.
Example (b): as shown in fig. 1, the front cross-sectional view of the elevator roller according to the embodiment of the present invention includes a rolling bearing 1, an outer ring 2, a rolling clamping groove 3 and a roller wear layer 4, wherein the outer ring 2 is coated on the outer surface of the rolling bearing 1, the circumferential surface of the outer ring 2 is connected to the rolling clamping groove 3, and the roller wear layer 4 is arranged in the rolling clamping groove 3; the diameter of the opening a is smaller than that of the rolling bearing 1, and the diameter of the opening c is larger than that of the rolling bearing 1. The rolling card slot 3 is a concave rolling card slot. The roller wear-resistant layer 4 is a concave arc surface.
In order to further enhance the roller life, the roller wear layer 4 is a thermoplastic resin.
As shown in fig. 2, the elevator roller according to the embodiment of the present invention has a side cross-sectional view, and the circumference of the opening c has a plurality of inwardly protruding bayonets 5.
The utility model discloses an elevator gyro wheel spare part is few, and every part cost is little, and the volume is also less, consequently can store easily or transport. And the small size of the assembly also reduces the requirements on the manufacturing equipment. The bearing bayonet has simple structure, does not need an end cover or a retainer ring, is not easy to damage and has long service life.
The above embodiment is only for explaining the utility model discloses a technical thought, can not injecing with this the utility model discloses a protection scope, all according to the utility model provides a technical thought, any change of doing on technical scheme basis all falls into the utility model discloses within the protection scope.
