[0002] Stainless steel bars are an important raw material for the processing of mechanical parts. During the processing of some shaft components, the ends and outer surfaces are usually processed directly. When used in shaft transmission structures, the smoothness of rotation at the mating position cannot be guaranteed, the lubricating fluid is difficult to accurately add during mating, the wear during rotation is relatively large, and the heat resistance during use is also relatively poor.

The combination of lubricating liquid can ensure better smoothness during the rotation process and more reliable wear resistance. The overall safety and stability during use are more guaranteed, and the stability during the rotation process is also better, which can meet the needs of the transmission components with relatively high stability requirements.

[0017] like Figures 1 to 6As shown, a rotating stainless steel bar comprises a cylindrical stainless steel bar main structure 1. A cylindrical main mounting clamping groove 2 is provided in the middle of the stainless steel bar main structure 1, which provides a complete clamping fit. A fully-through cylindrical center mounting safety hole 3 is provided at the central axis of the stainless steel bar main structure 1, ensuring ventilation or lubrication flow at the center during use, thereby enhancing the heat resistance of the main structure. A cylindrical lubrication safety connection groove 4 is provided at one end of the center mounting safety hole 3, allowing lubrication of this end with lubricating fluid during use. Spherical rotational safety grooves 5, evenly distributed around the circumference of the stainless steel bar main structure 1, are provided on one end surface of the lubrication safety connection groove 4 to accommodate ball bearings for mounting. After installation, the ball bearings are retained by a stop plate. The depth of the rotational safety grooves 5 is less than two-thirds of their diameter, ensuring greater assembly stability during mounting. Installation and mounting are more convenient. The rotational safety matching groove 5 is in communication with the lubrication safety connection groove 4, which can ensure that the ball-type components are lubricated more evenly and safely during use, and ensure that the overall rotation stability and smoothness during use are better. The width of the intersection of the lubrication safety connection groove 4 and the rotational safety matching groove 5 is less than half the diameter length of the rotational safety matching groove 5, which prevents the ball position from deviating and ensures that the safety during use is better. It has a hollow structure at the center of the main structure, which has ventilation and lubrication functions during use, ensuring that the overall heat resistance during use is stronger. By setting a lubrication structure and a rotation matching structure at one end, it can be used together with the ball-type components during use. The combination of lubricating liquid can ensure better smoothness during rotation and more reliable wear resistance. The overall safety and stability during use are better guaranteed, and the stability during rotation is also better, which can meet the needs of transmission components with relatively high stability requirements.

[0018] Preferably, the outer edges of both sides of the main body mounting clamping groove 2 are provided with matching avoidance chamfer structures, which have a better avoidance effect during clamping and fitting installation, making the installation operation more convenient.

[0019] Preferably, a mating safety rounded corner structure is provided on both sides of the width of the intersection of the lubrication safety connection groove 4 and the rotation safety mating groove 5, so that the ball mating position is smoother during rolling mating, avoiding the existence of sharp corner structures, ensuring higher rotation during mating, and further improving durability.

[0020] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or substitutions can be made without departing from the principles described in the present invention. These improvements or substitutions should also be regarded as the scope of protection of the present invention.
