The bearing is installed in the bearing installation position. An annular clamping groove is formed between the upper part and the lower part of the bearing body. The diameter of the through hole is 8 mm. And 10-14 supporting reinforcing ribs are arranged in the lower part of the bearing body. And 10-14 damping ribs are arranged on the periphery of the bearing body. The utility model has the advantages that: the shaft is suitable for super-long small shafts, and is more and quieter in matched models.

Description

Through hole bearing seat

Technical Field

The utility model relates to a bearing frame, in particular to through-hole bearing frame belongs to bearing frame technical field.

Background

The bearing and the bearing seat are widely used in various household appliance brands of air conditioners and automobile air conditioners and mainly used for reducing abnormal sound generated when the steel shaft of the wind wheel and the bearing rotate and rub. The products used today are due to structural problems:

1. the old product has a single machine type, so that the machine type cannot be universal, and the matching degree is low and the product has jitter when other products are used;

2. the old product does not have the through-hole, when touch motor shaft minor axis length overlength, touches the rubber end and arouses the friction noise.

SUMMERY OF THE UTILITY MODEL

The utility model aims at above-mentioned prior art in, not having the through-hole, producing the defect of noise, providing a through-hole bearing frame, can be fit for overlength staff, the purpose that the cooperation model is more, more silent.

In order to realize the purpose, the utility model adopts the technical scheme that: a through hole bearing seat, which is called bearing seat for short, is assembled with a fan for use, and comprises a bearing body; the bearing body comprises an upper part, a lower part, a bearing mounting position and a through hole, wherein the bearing mounting position is positioned below the center of the bearing body; the upper part of the bearing mounting position is provided with a through hole. The bearing is installed in the bearing installation position.

An annular clamping groove is formed between the upper part and the lower part of the bearing body. Used for clamping the fixed support after assembly.

The diameter of the through hole is 8 mm.

And 10-14 supporting reinforcing ribs are arranged in the lower part of the bearing body.

And 10-14 damping ribs are arranged on the periphery of the bearing body.

The diameter of the clamping groove is smaller than the whole diameter of the bearing body.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the original sealed end face is removed through deconstruction design, and meanwhile, the diameter of the through hole is increased to 8mm (the motor small shaft is 6mm) in order to avoid the contact friction of the motor shaft small shaft, so that the small shaft cannot touch the hole wall to cause friction noise when rotating;

2. structurally match all plastics fixed bolster, it is that the product commonality is wider in the aspect of the use, can realize unifying on many models of type, has solved the complicated puzzlement of customer specification.

Description of reference numerals: the bearing comprises a bearing body 1, an upper part 101, a lower part 102, a supporting reinforcing rib 103, a damping rib 104, a bearing mounting position 2, a through hole 3 and a clamping groove 4.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific examples, which are not intended to limit the present invention.

As shown in fig. 1 to 4, a through-hole bearing seat, referred to as a bearing seat for short, is assembled with a fan for use, and includes a bearing body 1; the bearing body 1 comprises an upper part 101, a lower part 102, a bearing mounting position 2 and a through hole 3, wherein the bearing mounting position 2 is positioned at the lower position of the center of the bearing body 1; a through hole 3 is arranged above the bearing mounting position 2. Bearings (not shown) are mounted in the bearing mounting locations 2.

An annular clamping groove 4 is arranged between the upper part 101 and the lower part 102 of the bearing body. Used for clamping the fixed support after assembly.

The diameter of the through hole 3 is 8 mm.

12 supporting reinforcing ribs 103 are arranged in the lower part 102 of the bearing body 1.

The bearing body 1 is provided with 12 shock absorption ribs 104 at the periphery.

The diameter phi A of the clamping groove 4 is smaller than the overall diameter phi B of the bearing body 1.

The specific use method comprises the following steps: the bearing block is arranged on a fixed support opposite to a motor shaft of an electric appliance such as an air conditioner, a fan, an air supply fan and the like, the bearing block is matched with a resin bearing for use, a small shaft of the motor shaft is inserted into the resin bearing arranged in the bearing block, one end of the small shaft penetrates through a through hole, when a power supply is started, the through-flow fan blade rotates fast, the motor drives the small shaft to rotate in the resin bearing, at the moment, the bearing block buffers and consumes shaking caused by rotation of the fan blade, the whole machine is guaranteed not to vibrate during operation, and the function of muting is achieved.

The above-mentioned embodiments are only preferred embodiments of the present invention, and the ordinary changes and replacements within the technical scope of the present invention should be covered by the protection scope of the present invention.
