Abstract

The utility model discloses a spring-type rotating shaft structure for reducing wear, comprising a main shaft, a support frame, two groups of spring sheets, a plurality of washers and a nut. The support frame, the spring sheets, the washers and the nut all penetrate the main shaft. The main shaft is in the shape of a column with a waist hole, and the center of the first group of spring sheets is a round hole, and the center of the second group of spring sheets is a waist hole. Therefore, the second group of spring sheets will be fixed on the main shaft. When the support frame rotates, the second group of spring sheets does not move, and the first group of spring sheets and the support frame rotate in the same direction and disperse the friction force to the second group of spring sheets. In addition, a degreasing groove is provided on the side of the second group of spring sheets close to the support frame to reduce the wear of the first group of spring sheets and increase their service life.

Shrapnel shaft structure to reduce wear

technical field

The utility model relates to a rotating shaft structure, in particular to a shrapnel type rotating shaft structure which can reduce wear.

Background technique

All kinds of rotating hinges have been developed in the wisdom of everyone. As long as they are rotatable and openable products, they must include hinges, such as single-axis hinges, double-axis hinges, and wrap-around hinges. , shrapnel type hinges, inline hinges, etc., different hinges have their own different purposes, using these shaft structures can make life more convenient.

The shrapnel-type rotating shaft structure in the prior art only includes one set of shrapnels. As shown in FIG. The support frame 12 , the elastic piece 14 and the washer 16 are passed through the main shaft 10 in sequence, and the nut 18 is fixed at the end of the main shaft 10 . Two shrapnels 14 are arranged on both sides of the bracket 12 respectively.

When the support frame rotates, the first group of shrapnel is driven by the support frame and rotates, and the second set of shrapnel is fixed on the main shaft. At this time, the friction force of the support frame on the first group of shrapnel will be distributed to the second group. On the shrapnel, the wear of the first group of shrapnel is reduced and the service life is increased, and the positions of the first group of shrapnel and the second group of shrapnel can be interchanged.

Compared with the prior art, the utility model has the following advantages:

The utility model proposes a shrapnel-type rotating shaft structure that reduces wear and tear. The structure is simple, and the new lubricating system can reduce wear and increase the life of the shrapnel.

Detailed ways

The utility model provides a shrapnel type shaft structure for reducing wear, as shown in Figure 2 and Figure 3, which includes a main shaft 20, a support frame 22, a first group of shrapnel 24, a second group of shrapnel 26, a plurality of Washer 28 and a nut 30, the shape of the main shaft 20 is a waist hole shape, a positioning ring 204 is arranged on the top of the main shaft 20, and a plurality of screw teeth 202 are arranged at the end, and the nut 30 is locked on the end screw teeth 202 of the main shaft 20 The bearing frame 22 is L-shaped and is arranged on the main shaft 20; the first group of shrapnel 24 and the second group of shrapnel 26 each include two shrapnels, which are respectively located on both sides of the bearing frame 22, and the perforation in the center of the first group of shrapnel 24 is It is circular, and is provided with six round holes 242 on it, and the perforation in the center of the second group of shrapnel 26 is a waist hole, which can be fixed on the main shaft 20, and four round holes 262 are arranged on the second group of shrapnel 26; The washers 28 are disposed on the main shaft 20 and at the front end of the nut 30 , and each washer 28 is provided with a central hole for fixing on the main shaft 20 .

An annular oil storage tank 264 and a cross-shaped oil storage tank 266 are arranged on the second group of shrapnel 26, as can be clearly seen in Fig. 3 and Fig. 4, the depth of the two oil storage tanks 264, 266 is half of the thickness of the second group of shrapnel 26 , and the two oil storage tanks 264, 266 are all located on the side close to the support frame 22, when the support frame 22 rotates, the lubricating oil in the oil storage tanks 264, 266 is applied to the support frame 22 or the first group of shrapnel 24, It can make the rotation more smooth and reduce the abrasion of the first group of elastic pieces 24 and the second group of elastic pieces 26 . The positions of the first group of elastic sheets 24 and the second group of elastic sheets 26 can be exchanged, or as long as the central circular hole and the waist hole of the first group of elastic sheets 24 and the second group of elastic sheets 26 are interchanged. Fig. 5 is a side view of the utility model, from which it can be seen that the fitting relationship of each component of the utility model.

Because the central perforation of the second group of elastic pieces 26 is a waist hole, which can fit together with the shape of the main shaft 20, so when the support frame 22 rotates, the second group of elastic pieces 26 are fixed, while the first group of elastic pieces 24 follow the bearing. The frame 22 rotates and distributes the friction force to the second group of elastic pieces 26. Although the first group of elastic pieces 24 will be driven by the friction force of the bracket 22 to rotate, but because the friction force is dispersed on the second group of elastic pieces 26, the second group of elastic pieces 24 The degree of rotation of one group of elastic pieces 24 will be smaller than the rotation degree of the support frame 22, so that the first group of elastic pieces 24 will rotate with the support frame 22 in a half-running and half-stop state.

To sum up, the shrapnel type rotating shaft structure provided by the utility model is to fix the second group of shrapnel on the main shaft by adding a second group of shrapnel, and setting an oil storage tank on it as a new type of shaft lubrication system, and The first group of shrapnels rotates with the rotation of the support frame, allowing the second group of shrapnels to share the friction force of the first group of shrapnels, so as to reduce the abrasion of the first group of shrapnels and prolong the service life of the rotating shaft.
