Description

Technical Field

[0001] This utility model relates to the field of high-speed fan technology, and in particular to a novel damping rotation structure for a high-speed fan. Background Technology

[0002] High-speed fans are industrial-grade equipment characterized by high rotational speed, enabling efficient gas transport. They typically refer to ventilation equipment with rotational speeds exceeding 18,000 rpm, with some models reaching 21,000-25,000 rpm. These ultra-high speeds generate large air volumes (85-6000 cubic meters per hour) and high air pressures (50-290 mbar), achieving an efficiency of over 95%. Currently, the rotational function of high-speed fan ducts generally uses plastic friction damping, which suffers from rapid damping and short lifespan. Therefore, we propose a novel damping rotational structure for high-speed fans. Summary of the Invention

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a new type of damping rotation structure for a high-speed fan. The blower of this technical solution uses a mechanical metal damping structure, which makes its lifespan exceed 10,000 cycles.

[0004] To achieve the above objectives, a novel damping rotation structure for a high-speed fan is provided, comprising: a fan body, an installation groove on the fan body, a sleeve disposed in the installation groove, and a first fixed seat and a second mounting seat respectively connected to the top and bottom of the sleeve, and a damping rotating shaft passing through the sleeve.

[0005] According to the novel damping rotation structure of a high-speed fan, the outer sleeve is provided with a damping plate and a gasket.

[0006] According to the novel damping rotation structure of a high-speed fan, a nut is sleeved on the bottom end of the damping shaft, and the top of the nut is in contact with the washer below.

[0007] According to the novel damping rotation structure of a high-speed fan, an end cover is provided on the top of the mounting groove, and a fastening screw is provided between the bottom of the end cover and the first fixed seat.

[0008] The above solution has at least one of the following beneficial effects: a new type of damping rotation structure for a high-speed fan adopts a metal mechanical damping structure, which is suitable for different needs and has four damping positions, thereby improving its applicability and efficiency.

[0009] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0016] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0017] Reference Figures 1 to 3 This utility model provides a novel damping rotation structure for a high-speed fan, comprising a fan body 1, an installation groove 9 on the fan body 1, a sleeve 5 inside the installation groove 9, and a first fixed seat 2 and a second mounting seat 3 connected to the top and bottom of the sleeve 5 respectively. A damping rotating shaft 4 passes through the sleeve 5. This technical solution uses a mechanical metal damping structure for the blower, resulting in a lifespan exceeding 10,000 cycles.

[0018] A damping plate 6 is fitted over the sleeve 5, and a washer 7 is also fitted over the sleeve 5. A nut 10 is fitted over the bottom end of the damping shaft 4, and the top of the nut 10 fits against the washer 7 below. An end cap 11 is provided on the top of the mounting groove 9, and a fastening screw 8 is provided between the bottom of the end cap 11 and the first fixing seat 2. This structure, employing a metal mechanical damping structure, is suitable for different needs, offering four damping positions, thus improving its applicability and efficiency.

[0019] Working principle: When using this technical solution, first remove the end cap 11 and fastening screw 8, and take out the sleeve 5 from the mounting groove 9. Then remove the nut 10 and remove the first fixing seat 2 and the second mounting seat 3 in sequence. The positions of the damping plates 6 and 7 can be changed according to the figure. Then reassemble and install them in the mounting groove 9, so that it adopts a metal mechanical damping structure, which is suitable for different needs. There are four damping positions, which improves its applicability and efficiency. The blower uses a mechanical metal damping structure, which makes its lifespan exceed 10,000 times.
