Problems solved by technology

[0003] To assemble the four-gear transmission mechanism in the prior art is to first arrange the approximate positions of the four gears according to the known condition that the index circles are tangent to each other when the four-gear transmission mechanism meshes; And repeatedly adjust until the gears of the four-gear transmission mechanism can rotate at the same time, but this assembly method is inefficient and largely depends on the subjective judgment of the assembler. The assembled four-gear transmission mechanism often cannot meet the assembly accuracy requirements (ie Adjacent gears are correctly meshed), and when the assembly accuracy of the four-gear transmission mechanism cannot meet the requirements, it will lead to the following situations: 1. The gears are difficult to drive accurately and smoothly, resulting in impact and noise
2. The wear between the gears is aggravated during the transmission process, which affects the service life of the gears
3. The transmission process is prone to teeth gnashing phenomenon caused by gear vibration or gear tooth friction heat expansion

Embodiment Construction

[0014] like figure 1 , figure 2 As shown in the figure, a four-gear transmission mechanism according to the present invention includes four gears 1, 2, 3, and 4 arranged together. The sizes of the four gears 1, 2, 3, and 4 can be selected according to actual needs. The index circles of the adjacent gears are tangent, and the center positions of the index circles of the four gears 1, 2, 3, and 4 are based on the formula To determine and arrange, among which, the four points A, B, C, D are the tangent points between the index circles of adjacent gears; for ∠AO 1 The arc length of the arc segment where B is less than 180°; for ∠BO 2 The arc length of the arc segment where C is greater than 180°; for ∠CO 4 The arc length of the arc segment where D is less than 180°; for ∠AO 3 The arc length of the arc segment where D is less than 180°; is the gear modulus, which is the standard value, It is the pitch of the gears, and the pitches of the four gears 1, 2, 3, and 4 ...

Abstract

The invention discloses a four-gear transmission mechanism and an installation method thereof. The four-gear transmission mechanism comprises four gears arranged together, reference circles of adjacent gears are tangent in pairs, and the positions of the centers of the reference circles of the four gears are determined and arranged according to a formula (overarc(AB) + overarc(BC) + overarc(CD) C overarc(AD)) / mpi=integer+-0.1. In the four-gear transmission mechanism disclosed by the invention, the gears adjacent in pairs can precisely meshed and meet the requirements on installation precision. Compared with the prior art, the four-gear transmission mechanism has the following advantages that: the gears can precisely and stably transmit to prevent impaction and noise generation; the abrasion among the gears during the transmission can be largely reduced, and the service lives of the gears are prolonged; in addition, the situation of gear meshing due to gear vibration or gear friction heating expansion during the transmission can be prevented.

Description

technical field [0001] The invention relates to a gear transmission mechanism, in particular to a four-gear transmission mechanism and an assembling method thereof. Background technique [0002] The four-gear transmission mechanism is composed of four gears that are arranged together and whose gear shafts are parallel to each other. The centers of the four gears are distributed in a quadrangle, and two adjacent gears mesh with each other. During operation, the main transmission gear can drive other gears. The three driven gears rotate at the same time to realize the movement and power transmission between the gears. [0003] To assemble a four-gear transmission mechanism in the prior art, firstly, the approximate positions of the four gears are arranged according to the known condition that their index circles are tangent when the four-gear transmission mechanism is engaged; And repeatedly adjust until the gears of the four-gear transmission mechanism can rotate at the same...
