Problems solved by technology

[0002] Gears are mechanical elements that rely on tooth surfaces to mesh with each other for transmission. When two gears mesh, the teeth of one of the gears always push into the tooth groove (root) of the other gear. Due to the machining accuracy, the gear The teeth and the tooth grooves cannot be completely matched, that is, there is a gap between the teeth and the tooth grooves. When the width of the teeth and the tooth grooves is large, this gap is enlarged. In addition, the wear caused by transmission will also cause This gap gradually increases. When there is a large gap between the teeth and the tooth groove, the meshing between the two gears is not tight enough, which reduces the transmission accuracy. loud noise

Embodiment Construction

[0014] Further description will be given below in conjunction with the accompanying drawings and preferred embodiments of the present invention.

[0015] like figure 1 , figure 2 , image 3 As shown, this gear mechanism that can automatically adjust the gap includes a first gear 1 and a second gear 2 that are meshed; the first gear 1 includes a left minute gear 101, a right minute gear 102, a plurality of locking screws 103 and two An elastic mechanism 104; the left minute gear 101 is provided with a plurality of locking screw holes 105, and the right minute gear 102 is provided with a plurality of arc-shaped through holes 106, and the arc-shaped through holes 106 correspond to the locking screw holes 105 one by one. The left sub-gear 101 and the right sub-gear 102 are locked together by a plurality of locking screw rods 103, wherein the locking screw rods 103 pass through the corresponding arc-shaped through holes 106 and are in the corresponding locking screw holes 105; ...

Abstract

A gear mechanism capable of automatically adjusting the gap comprises a first gear and a second gear which are engaged. The first gear comprises a left divided gear, a right divided gear, locking screws and an elastic mechanism. The left divided gear and the right divided gear are locked together through the multiple locking screws. The elastic mechanism is arranged between the inner side face of the left divided gear and the inner side face of the right divided gear. After the left divided gear and the right divided gear are locked, the left divided gear and the right divided gear cannot relatively move in the axial direction, and when the first gear and the second gear are engaged, the left divided gear and the right divided gear overcome elastic force of the elastic mechanism and relatively rotate with the small amplitude, accordingly, a tooth groove of the left divided gear and a tooth groove of the right divided gear are staggered with the corresponding amplitude and automatically matched with gear teeth, uneven in the axial direction, of the second gear, the tooth groove of the left divided gear and the tooth groove of the right divided gear closely coincide with the corresponding parts of the gear teeth of the second gear, the gap between the first gear and the second gear is automatically eliminated, the transmission precision is improved, and noise is lowered.

Description

technical field [0001] The invention relates to a gear, in particular to a gear mechanism capable of automatically adjusting gaps. Background technique [0002] Gears are mechanical elements that rely on tooth surfaces to mesh with each other for transmission. When two gears mesh, the teeth of one of the gears always push into the tooth groove (root) of the other gear. Due to the machining accuracy, the gear The teeth and the tooth grooves cannot be completely matched, that is, there is a gap between the teeth and the tooth grooves. When the width of the teeth and the tooth grooves is large, this gap is enlarged. In addition, the wear caused by transmission will also cause This gap gradually increases. When there is a large gap between the teeth and the tooth groove, the meshing between the two gears is not tight enough, which reduces the transmission accuracy. Loud noise. Contents of the invention [0003] The technical problem to be solved by the present invention is t...
