Transmission element with spacers

Abstract

The invention provides a ball with spacers, which comprises a first element, a second element, a plurality of balls and a plurality of spacers. A rolling trench is arranged on the first element, the second element is provided with a rolling groove which corresponds to the rolling trench, the plurality of balls are arranged between the rolling trench and the rolling groove, the plurality of spacers are arranged among the balls, the outline of each spacer nearly presents the shape of a sphere, each spacer is provided with six retaining grooves, and the retaining grooves are symmetrical to each other two by two. When the balls are separated from the retaining grooves of the spacers, with the characteristics that the retaining grooves are arranged at the six faces of each spacer and the outline of each spacer nearly presents the shape of the sphere, the spacers can be matched with the balls after turning to any retaining groove at will, so as to achieve the effect of spacing the balls.

Description

technical field [0001] The invention relates to an accessory of a transmission element, in particular to a spacer arranged inside the transmission element and spaced apart from balls. Background technique [0002] see Figure 7 As shown, it is a schematic diagram of a conventional transmission element with a spacer 14. The spacer 14 is made of plastic material, and it is installed on the first element 10. The two sides of the spacer 13 are set as concave arc surface, the function of the spacer 14 is to separate the adjacent balls 13, to prevent the balls 13 from colliding with each other and making noise when rolling, and each ball 13 and the spacer 14 are in close contact, so that the spacer 14 is mutually The two adjacent balls 13 are clamped to form a suspended state, but because the entire concave arc surface of the spacer 14 is constantly rubbed by the balls 13 made of metal steel, the two concave arc surfaces of the single spacer will be worn and slightly Shrinking, s...

Problems solved by technology

[0002] see Figure 7 As shown, it is a schematic diagram of a conventional transmission element with a spacer 14. The spacer 14 is made of plastic material, and it is installed on the first element 10. The two sides of the spacer 13 are set as concave arc surface, the function of the spacer 14 is to separate the adjacent balls 13, to prevent the balls 13 from colliding with each other and making noise when rolling, and each ball 13 and the spacer 14 are in close contact, so that the spacer 14 is mutually The two adjacent balls 13 are clamped to form a suspended state, but because the entire concave arc surface of the spacer 14 is constantly rubbed by the balls 13 made of metal steel, the two concave arc surfaces of the single spacer will be worn and slightly Shrinking, so that there is a gap between the ball 13 and the spacer 14, and the number of spacers in the first element 10 is quite large. When the accumulated wear of each spacer 14 is too much, the transmission element will vibrate during operation. , it will cause the spacer 141 (142) at some positions to break away from the balls 13, and wear with the bottom surface of the rolling groove 12, or collide with the inlet end of the return element 15, causing the entire ball 13 to roll unsmoothly and make noise , and wear out the internal components

In addition, the ball 13 and the spacer 14 cannot fill the entire rolling groove 12 due to the size fit relationship with the rolling groove 12 of the first element 10 during assembly, resulting in a gap between the ball 13 and the spacer 14, so the same The above-mentioned problems will also occur, and relatively, the circulation of the transmission components will not be smooth

And if the conventional spacer 14 is toppled and the ball loses the space effect, it will be difficult to restore the original space state.

Therefore, the conventional transmission element with spacer 14 still needs to be improved.
