Definitions

  • the present invention is to improve the power transmission efficiency, which is the biggest drawback of the conventional worm gear, to a level equal to that of a general gear, and to the level of a bearing.
  • worm gears have been generalized as gears with unique characteristics such as right-angle transmission of power, self-locking, and extinction ratio.
  • bevel gears are 1/2 or 1/3, planetary gears are 1/5 to 110, but worm gears are also 1/20 to 1Z100.
  • the transmission efficiency was as low as 40% to 50%, and was around 80% even for those with high processing accuracy. This is because, in principle, the power is transmitted by the component force due to the friction between the worm gear and the worm wheel, so the loss increases.
  • the casing prevents falling off, the shape of the worm gear is a drum shape, and the worm wound worm is a ball groove. Hit at the same time, strengthen the action.
  • the transmission efficiency was more than 90%, and a high-speed input of 50,000 r Pm or more, which was impossible, was made possible.
  • FIG. 1A is a cross-sectional view of a horizontal mechanism
  • FIG. 2 is a cross-sectional view of a vertical mechanism.
  • Reference numeral (1) indicates a drum-shaped ball groove worm gear
  • (2) indicates a ball wheel gear.
  • connection tt between (1) and (2) is important and requires the most skill.
  • the diameter is small at the center of (1) and large at both sides.
  • the contact speed with the ball is slow at the center and fast at the edges.
  • the pitch of the round groove is so steep at the center that it stands at both ends.
  • the pitch of the round groove is twisted with the rotation position of (1).
  • the ball and the wheel 6 in (2) have a clearance of about 0.01 mm, can rotate freely, and surround the ball so that the ball does not fly out. Is smaller than the diameter of the ball.
  • the ball on the wheel which does not come into contact with the worm, is also held freely by the casing with a fixed rotation in the wheel hole.
  • the difference between the ball screw and the ball screw is explained. If the ball screw rotates in the round groove of the screw, smooth movement and high efficiency can be obtained. In order for the ball to roll in both the round groove screw and the ball groove, the ball must be circulated inevitably.
  • the rotation axis and the movement direction axis are the same, and the rotation ratio is 1.
  • the bearing is a circular motion of the ball. Therefore, on the extension of this idea, there is no speed ratio or right angle transmission.
  • the ball worm gear is a fixed point rotation on the wheel side, and the bearing acts as a gear.
  • the ball and worm gear of the present invention can achieve high efficiency and high-speed rotation input of 500 rpm or more, which were impossible with the conventional worm and gear, and are compact.
  • a new range of applications was pioneered as a high-power tool. Improve efficiency as a speed reducer in the power field.

Abstract

Un des objectifs de la présente invention est d'améliorer le rendement d'un mécanisme de transmission à vis sans fin. Dans celui-ci, qui comprend une vis sans fin et une roue, la vis est constituée d'une vis à gorge de roulement à billes (1) ressemblant à un tambour à main, tandis que la roue est constituée d'une roue à vis sans fin à billes (2) dans laquelle une bille vient s'encastrer à demi. De la sorte, la vis sans fin et la roue s'engrènent mutuellement.
