The transmission mechanism comprises a sun wheel (1), a first planet carrier (2), a second planet carrier (5), a first planet gear (3), a second planet gear (4), planet wheel pin shafts (6), first bearings (7) and a dual-connecting inner gear sleeve (10); the first and second planet gears are respectively arranged on the planet wheel pin shafts by the first bearings; the planet pin wheel shafts are arranged on the first and the second planet carriers respectively; the first and second planet gears are respectively in outer meshing with the sun wheel and in inner meshing with the dual-connecting inner gear; the transmission mechanism also comprises second bearings (8) and a spacing sleeve (9); the second bearings are respectively arranged at the first and second planet carriers; the spacing sleeve is arranged on the sun wheel and between the two adjacent second bearings. According to the planet differential transmission mechanism, the noise during operation of equipment is reduced, and the performance of the work of the whole machine is improved.
Description
Technical field
The present invention relates to a kind of driving mechanism, specifically a kind of planet differential driving mechanism, belong to mining transportation machinery technical field.
Background technique
As everyone knows, mine endless rope continuous drafter and haulage gear are colliery downhole equipments commonly used, mainly to use as auxiliary conveying equipments, and driving mechanism is the main driving mechanism in mine endless rope continuous drafter and haulage gear, for meeting the actual shipment requirement, the driving mechanism used at present is the floating type planet differential of employing mechanism usually, in running, due to planet differential mechanism sun gear and the planet wheel gap larger, cause running noises large, overall performance exceeds standard.
Summary of the invention
The problem existed for above-mentioned prior art, the invention provides a kind of planet differential driving mechanism, and for mine endless rope continuous drafter, haulage gear, the noise during operation of reduction equipment, improve the performance of complete machine work.
To achieve these goals, the technical solution used in the present invention is: a kind of planet differential driving mechanism, comprise sun gear, the first planet carrier, the second planet carrier, the first planetary pinion, the second planetary pinion, planet wheel bearing pin, clutch shaft bearing and duplex internal tooth casing, described the first planetary pinion, the second planetary pinion are arranged on respectively on the planet wheel bearing pin by clutch shaft bearing, and the planet wheel bearing pin is separately positioned on the first planet carrier and the second planet carrier; Described the first planetary pinion, the second planetary pinion respectively with the sun gear outer gearing, with the duplex internal gear in mesh, also comprise the second bearing and spacer, the second bearing is arranged on respectively on the first planet carrier, the second planet carrier, and spacer is arranged on sun gear and between two the second adjacent bearings.
Compared with prior art, the present invention is transformed traditional planet differential mechanism, by between sun gear and the first planet carrier, the second planet carrier, having increased by the second bearing, make sun gear, planet wheel be changed into relatively fixing by original Relative Floating, guaranteed sun gear and planet wheel relative positional accuracy each other, improved the transmission accuracy between sun gear and planet wheel, eliminate between the two and cause transmission accuracy not high because position is unsteady, cause the higher problem of planet differential mechanism driving noise.
