Description

Technical Field

[0001] The utility model relates to a high-load rotating shaft, belonging to the technical field of rotating shaft parts. Background Art

[0002] Rotation is a common type of motion. When an object rotates, all its points move in circles, and the centers of these circles are on the same straight line, which is called the "rotation axis". Doors, windows, grinding wheels, motor rotors, etc. all have fixed rotation axes and can only rotate, not move horizontally. Several forces act on an object, and their rotational effects on the object are determined by the algebraic sum of their torques. If the algebraic sum of the torques is equal to zero, the object will rotate at a uniform speed or remain stationary at the original angular velocity.

[0003] The Chinese patent number CN114475237A is an insertable lightweight automobile rotating shaft, which belongs to the technical field of automobile rotating shafts. The U-shaped mounting seat is installed on the bottom plate of the vehicle body, and the motor driven by the vehicle body is started to drive the first inner slide bar and the first inner limit slide rail to rotate, further driving the first outer slide cylinder to rotate. When the annular slot and the retaining ring are in the engaging position, the second outer slide cylinder will be driven to rotate synchronously, and then the second outer slide cylinder will drive the second bevel gear to rotate, and the second bevel gear will drive the bevel gear of the front end driving the front wheel to rotate through the second bevel gear, thereby adjusting the movement of the front wheel to run on a flat straight track.

[0004] A stretched corrugated cover needs to be installed at the end connection position of the rotating shaft body to protect it in order to ensure its service life. However, when the stretched corrugated cover follows the rotating shaft body and the frequency is too high, the connection between the corrugated single ring body in the stretched corrugated cover will be worn, making it no longer complete and its protective ability reduced. Frequent maintenance and replacement are required, which is not conducive to ensuring the use efficiency of the rotating shaft body.

[0005] For this purpose, a highly loaded rotating shaft is proposed. Utility Model Content

[0006] In view of this, the utility model provides a high-load rotating shaft to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0007] The technical solution of the utility model is achieved as follows: a high-load rotating shaft, including a stretched corrugated cover body installed outside the rotating shaft body, the stretched corrugated cover body including a plurality of corrugated single-ring bodies, the plurality of corrugated single-ring bodies are stacked up and down, the plurality of corrugated single-ring bodies are equidistantly enlarged from front to back, a plurality of disc bodies are fixedly connected to one end of two adjacent corrugated single-ring bodies close to each other, the plurality of disc bodies are equidistantly arranged in a ring shape, an auxiliary spring is fixedly connected between two upper and lower corresponding disc bodies, and an inner ring connecting piece is fixedly connected to the inner end of the corrugated single-ring body.

[0008] Further preferably, an end of the inner ring connecting piece away from the corrugated single ring body is fixedly connected to an elastic mesh layer, and the elastic mesh layer is connected to the inner ring connecting piece.

[0009] Further preferably, a plurality of red warning soft strips are fixedly connected to one end of the inner ring connecting piece close to the corrugated single ring body, and the plurality of red warning soft strips are arranged at equal distances.

[0010] Further preferably, a damage point is formed at the outer end of the corrugated single ring body, and the red warning soft strip extends through the damage point to the outside of the corrugated single ring body.

[0011] Further preferably, one end of the stretched corrugated cover body close to the rotating shaft body is fixedly connected with a connecting front ring, and the connecting front ring is located outside the rotating shaft body.

[0012] Further preferably, one end of the stretched corrugated cover away from the rotating shaft body is fixedly connected to a fixed base, and the rear end of the fixed base is fixedly connected to a connecting disk.

[0013] Further preferably, a plurality of bolts are installed at the outer end of the connecting plate, and the bolts are externally connected to the base surface of the automobile chassis.

[0014] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0015] 1. In this scheme, the rotating shaft body is installed in a rotating device on the base surface of the automobile chassis for use. When the stretched corrugated cover is installed at the connection of the rotating shaft body, a number of disc bodies are added adjacent to the corrugated single ring body of the stretched corrugated cover. The auxiliary springs in the number of disc bodies can bear the strength of the stretching between two adjacent corrugated single ring bodies, so that the connection between the corrugated single ring bodies of the stretched corrugated cover is not easy to be damaged quickly, which is beneficial to ensure the protection efficiency of the stretched corrugated cover outside the rotating shaft body, reduce the maintenance frequency, and thus ensure the operation stability of the rotating shaft body.

[0016] 2. At the same time, an inner ring connecting piece can be arranged in the corrugated single ring body. The elastic mesh layer in the inner ring connecting piece can play a backup protection role when a damaged point appears, so as to prevent the external particles from forcibly entering the stretched corrugated cover through the damaged point and causing damage to the rotating shaft body, which is beneficial to ensure the use efficiency of the rotating shaft body. At the same time, a number of red warning strips are arranged on the outside of the inner ring connecting piece. After the damaged point appears, the red warning strips can be dropped out of the stretched corrugated cover, so that the maintenance personnel can promptly notice that maintenance is needed here.
