Problems solved by technology

[0003] Nylon pulleys are widely used in elevators. At present, nylon pulleys commonly used in elevators have the following defects: 1. Due to the direct contact between the bearing and the nylon, the bearing will loosen and swim during operation due to the difference in expansion coefficient, which brings safety hazards; 2. 1. The end of the bearing is exposed to the air for a long time and is easily corroded, which affects the life of the bearing; 3. It is time-consuming to replace the lubricating oil

Embodiment Construction

[0020] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the embodiments and accompanying drawings. The embodiments are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0021] Such as figure 1 It shows a specific embodiment of a pulley with a composite structure of the present invention: it includes a nylon wheel body 1 provided with a rope groove, the wheel body 1 is provided with a grease nozzle 4, and also includes a rotating shaft 3 and a rotating shaft movably connected to the wheel body 1. Its bearing 2, the inner side of the wheel body 1 and the bearing 2 are provided with a bushing 5, and the axial ends of the rotating shaft 3 are respectively provided with dust-proof covers 6, and the dust-proof covers 6 are provided with oil Holes 7 and dust cover 6 can also be made of metal materials and non-metallic ...

Abstract

The invention discloses a pulley with a composite structure, which comprises a nylon wheel body provided with a rope groove, an oil nozzle is arranged on the wheel body, and a rotating shaft and a bearing thereof movably connected to the wheel body, the inside of the wheel body and the bearing There are bushings between them, and the axial ends of the rotating shaft are respectively covered with dust-proof covers, and oil holes are arranged on the dust-proof covers. The invention can greatly increase the running speed and load of the pulley, and can prevent the direct contact between the bearing and the nylon, and the phenomenon of loosening and swimming of the bearing during operation due to the difference in expansion coefficient, thereby improving the service life of the bearing. At the same time, because the oil outlet hole is set on the dust cover, it is very convenient to clean the bearing without dismantling the whole pulley.

Description

[0001] technical field [0002] The invention relates to a pulley, in particular to a composite structure pulley. Background technique [0003] Nylon pulleys are widely used in elevators. At present, nylon pulleys commonly used in elevators have the following defects: 1. Due to the direct contact between the bearing and the nylon, the bearing will loosen and swim during operation due to the difference in expansion coefficient, which brings safety hazards; 2. 1. The end of the bearing is exposed to the air for a long time and is easily corroded, which affects the life of the bearing; 3. It is time-consuming to replace the lubricating oil. [0004] Contents of the invention [0005] In order to overcome the above defects, the present invention provides a pulley with a composite structure, which can be used for high-speed and high-load elevators, has the advantages of convenient refueling and oil discharge, and long service life of wheels and bearings. [0006] The technica...
