Description
Technical field
The present invention provides a kind of rotary planetary reductor, belongs to middle-size and small-size excavator speed reducing machinery technical field.
Background technology
Rotary planetary apparatus structure in the variable delivery hydraulic system of current middle-size and small-size digging machine is complicated, process technology requires that height, manufacture difficulty are relatively big, and cost of manufacture is high.
Summary of the invention
In order to overcome the deficiency of existing middle-size and small-size excavator rotary planetary reductor, the present invention provides a kind of structure the easiest, uses two-stage planetary reduction device, and being meshed with ring gear through two-stage planet realizes the rotary planetary reductor of rotation of rotary table.The present invention solves its technical problem and the technical scheme is that a kind of rotary planetary reductor, and including reducer shell, gear ring, primary planet props up support plate assembly, secondary planet props up support plate assembly, output shaft, transition gear, travelling gear etc..Above-mentioned reducer shell and gear ring, primary planet prop up support plate assembly, secondary planet is propped up support plate assembly and used parts processing technology: the most existing rotary planetary reductor uses gear ring and reducer shell monolithic construction, material is cast iron, the performance of gear ring does not reaches requirement, easy to wear, service life is short；Reducer shell of the present invention uses split-type structural with gear ring, gear ring loads reducer shell after thick, finish turning → gear shaping → heat treatment → cylindrical grinding process route shapes and fixes, gear ring material is steel alloy, steel alloy has high intensity and toughness, quenching degree is also preferable, without obvious temper brittleness, has higher fatigue limit and anti-repeat impact ability after modifier treatment, low-temperature impact toughness is good, thus improves the performance of gear ring, the accuracy of manufacture, service life；The most existing planet props up support plate and is also adopted by monolithic construction, and material is cast iron, and planetary gear axle performance does not reaches requirement, and casting difficulty is big, and process technology requires height；Planet of the present invention props up support plate assembly and uses split-type structural, resolve into planetary gear axle and planet props up support plate and is processed, planetary gear axle is through thick, finish turning → boring → heat treatment → cylindrical grinding process route shapes, planet props up support plate through thick, finish turning → garland key → thick, finish turning → brill, fraising → face grinding process route shapes, after machining, planetary gear axle loading planet is propped up in support plate and fixes, planetary gear shaft material is pinion steel, pinion steel is carburizing steel of good performance, quenching degree is higher, there is after carburizing and quenching hard and wear-resisting surface and tough and tensile heart portion, there is higher low-temperature impact toughness, weldability is medium, after normalizing, machinability is good, ensure that the performance requirement of product, improve service life, parts processing improves the accuracy of manufacture of product, substantially increase the qualification rate of product.
Compared with prior art, it is an advantage of the current invention that gear ring and housing, primary planet prop up support plate assembly, secondary planet is propped up support plate assembly and all used parts processing: reduce product casting and processing and manufacturing difficulty, thus cost-effective；The shape of product is prone to correction reference face by complexity is random to simple rule, improves the accuracy of manufacture of product, substantially increases the qualification rate of product；Key position uses high performance material, reduces hazard rate, improves service life.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Fig. 2 is that the primary planet of the present invention props up support plate component drawings.
Fig. 3 is that the secondary planet of the present invention props up support plate component drawings.
Detailed description of the invention
Below in conjunction with the accompanying drawings embodiments of the invention are further described.
Reducer shell 1 material is spheroidal graphite cast-iron, shape through thick, finish turning → boring, tapping process route, gear ring 3 material is steel alloy, shapes through thick, finish turning → gear shaping → heat treatment → cylindrical grinding process route, then is press-fitted by gear ring 3 in loading reducer shell 1 and fastens.
Primary planet props up each parts of support plate assembly 2 and all uses parts processing technology, assemble again after processing: primary planet pinion axle 7 material is pinion steel, shape through thick, finish turning → boring → heat treatment → cylindrical grinding process route, it is spheroidal graphite cast-iron that primary planet props up support plate 10 material, through thick, finish turning → garland key → thick, finish turning → bore, ream → face grinding process route shapes；Primary planet pinion axle 7 is fixed on primary planet with the first pin 5 and props up on support plate 10, primary planet pinion 9 is contained on primary planet pinion axle 7, primary planet pinion 9 is middle with primary planet pinion axle 7 equipped with needle bearing 8, is fixed on primary planet pinion axle 7 by primary planet pinion 9 with axle check ring 6.
Secondary planet props up support plate assembly 4, and prop up support plate assembly 2 structure to primary planet similar, secondary planetary gear axle 13 is fixed on secondary planet with the second pin 11 and props up on support plate 16, second pin 11 is installed along the axially vertical direction with secondary planetary gear axle 13, secondary planetary gear 15 is contained on secondary planetary gear axle 13, secondary planetary gear 15 is middle with secondary planetary gear axle 13 equipped with needle bearing 14, is fixed on secondary planetary gear axle 13 by secondary planetary gear 15 with axle check ring 12.Secondary planet prop up support plate assembly 4 prop up with primary planet support plate assembly 2 processing and assemble method identical.
The rotary motion of main frame motor drive shaft is sent on the travelling gear that coupled by spline, three primary planet pinions by with travelling gear engage deceleration.Primary planet pinion is arranged on primary planet and props up on support plate, and transition gear props up support plate and couples with spline with primary planet, the rotation of primary planet pinion drives transition gear transmission, four secondary planetary gears are by realizing the double reduction of rotary planetary reductor with engaging of transition gear, and final secondary planet is propped up support plate and coupled with spline and drive output shaft output.
