Embodiment Construction
[0017] Such as figure 2 , image 3 As shown, the present invention is a gear transmission system that can eliminate gear transmission gaps, including gear A1 and gear B2 that are meshed with each other, wherein the upper end surface of gear A1 is concavely provided with a stepped surface 4 that can accommodate the movable gear 3, the The number of teeth, addendum circle diameter, and dedendum circle diameter of movable gear 3 are the same as those of gear A1, and the axis line of movable gear 3 coincides with that of gear A1. At the same time, the movable gear 3 meshes with gear B2, and the movable gear 3 The lower end surface of 3 is fixed with a fixed shaft 5 protruding downward, and the step surface 4 of the gear A1 is provided with an accommodating groove 6 capable of accommodating the fixed shaft 5, and a compressed elastic body 7 is also arranged in the accommodating groove 6 , one end of the compressed elastic body 7 withstands the side wall of the fixed shaft 5 , and...

The invention discloses a gear transmission system capable of eliminating a gear transmission clearance, and belongs to the technical field of gear transmission systems. The gear transmission system capable of eliminating the gear transmission clearance comprises a gear A and a gear B which are meshed with each other, wherein a step surface capable of accommodating a movable gear is concavely arranged on the upper end surface of the gear A; the tooth number, the tip diameter and the root diameter of the movable gear are the same as those of the gear A; the axis of the movable gear is superposed with the axis of the gear A; the movable gear is meshed with the gear B; a downwards protruding fixing shaft is fixed on the lower end surface of the movable gear; an accommodating slot capable of accommodating the fixing shaft is formed in the step surface of the gear A; a pressed elastomer is arranged inside the accommodating slot; one end of the pressed elastomer is pressed against the side wall of the fixing shaft; and the other end of the pressed elastomer is pressed against the side wall of the accommodating slot. The clearance between two mutually-meshed main gears can be eliminated by arranging the movable gear which can deflect, so that precise transmission between the two gears is achieved; and the gear transmission system is simple and practical in structure.
Description
technical field [0001] The invention discloses a gear transmission system capable of eliminating gear transmission gaps, and belongs to the technical field of gear transmission systems. Background technique [0002] Ordinary gear transmissions such as figure 1 As shown: a gear transmission system is composed of gear A1' and gear B2'. There is no transmission problem in general gear transmission. The following transmission gap problems occur: [0003] 1. The tooth thickness of gear A1' and gear B2' is relatively small in conventional processing, so there will be a gap between the teeth of the two gears during the assembly process. [0004] 2. During the normal operation of gear A1' and gear B2', the teeth of gear A1' and gear B2' will also wear and tear, making the tooth thickness smaller. The bigger the gap. [0005] In the case of the above-mentioned problems, the purpose of precise transmission between the two gears cannot be achieved. Contents of the...
