A sun gear of a one-level gear set is connected with the motor, and a planetary carrier of the three-level planetary gear set is connected with an output shaft. In the one-level gear set, a one-level sun gear is meshed with a one-level planet gear, and the one-level planet gear is meshed with a one-level annular gear and connected with a two-level sun gear in a two-level gear set through a one-level planetary carrier. In the two-level gear set, the two-level sun gear is meshed with a two-level planet gear, and the two-level planet gear is meshed with a two-level annular gear and connected with a three-level sun gear in a three-level gear set through a two-level planet gear. In the three-level gear set, the three-level sun gear is meshed with a three-level planet gear, and the three-level planet gear is meshed with a three-level annular gar and connected with a three-level planetary carrier which is connected with the output shaft. The integral planetary gear walking mechanism is compact in structure, large in driving force, low in cost, good in sealing, large in torque, light in weight and reliable in working.
Description
Technical field
The utility model relates to a kind of machine-walking structure, is specifically related to a kind of planetary pinion traveller that is used for crawler crane or excavator.
Background technique
The mechanical running mechanism of big machinery such as crawler crane or excavator generally adopts the Gear Planet Transmission traveller to carry out transmission, and existing Gear Planet Transmission traveller has fixed axis gear transmission traveller and cycloidal-pin wheel transmission traveller two big series.Because the influence of Environmental Conditions and operating conditions; Traveller requires output torque big; Bearing capacity is strong, and reliable operation, fixed axis gear transmission traveller exist a lot of not enough; No longer be applied in the big machineries such as crawler crane or excavator gradually, and shortcomings such as the cycloidal-pin wheel traveller is big because of volume, weight big, structure is not compact, cost height have also more and more satisfied not the needs of large-scale engineering machinery.In addition, also there are problems such as driving force is little, sealing is poor, working life is short in existing planetary pinion traveller.
The model utility content
Big, the above-mentioned deficiencies such as driving force is little, weight is big, structure is not compact, cost height of volume that the utility model exists to existing traveller; A kind of compact structure is provided, driving force is big, cost is low, good airproof performance and moment of torsion are big, in light weight, and the integrated type planetary pinion traveller of reliable operation.
The technological scheme of the utility model is: a kind of integrated type planetary pinion traveller; Comprise motor and speed reducer, described speed reducer comprises the third-level planetary gear train, wherein; The sun gear of one-level gear train is connected with motor, and the planet carrier of tertiary gear group is connected with output shaft; In the one-level gear train, the engagement of one-level sun gear and one-level planet wheel, one-level planet wheel and the engagement of one-level ring gear, and pass through primary planet carrier and be connected with secondary sun gear in the secondary gear group; In the secondary gear group, the engagement of secondary sun gear and secondary planet wheel, secondary planet wheel and the engagement of secondary ring gear, and be connected with three grades of sun gears in the tertiary gear group through the secondary planet frame; In the tertiary gear group, three grades of sun gears and the engagement of third-level planetary wheel, third-level planetary wheel and three grades of ring gears engagements, and be connected with the third-level planetary frame, the third-level planetary frame is connected with output shaft.
The beneficial effect of the utility model is: the utility model compact structure, driving force is big, cost is low, good airproof performance, and moment of torsion is big, in light weight and reliable operation.Adopt the third-level planetary transmission, the afterbody planet carrier directly is connected with output shaft, and the brakeless device, and volume is little, in light weight, during use, only needs to get final product through the cooperation of external break.
