Common three grades of speed reducers on the design handbook are two-piece unit combinations, common three grades of speed reducers as depicted in figs. 1 and 2, comprise casing 1 and the case lid 3 that removably connects by bolt 2, junction plane between casing 1 and the casing 3 successively parallel rotation is provided with input shaft 4, the first jack shaft 5, the second jack shaft 6 and output shaft 7, input shaft 4 is provided with input driver pinion a, the first jack shaft 5 is provided with the first driven gearwheel b and the first driver pinion c, the second jack shaft 6 is provided with the second driven gearwheel d and the second driver pinion e, output shaft 7 is provided with the driven gearwheel f of output, input driver pinion a and the first driven gearwheel b are connected by meshing transmission, the first driver pinion c and the second driven gearwheel d are connected by meshing transmission, and the second driver pinion e and the driven gearwheel f of output are connected by meshing transmission.By three grades of transmissions, reach the purpose of gearing down.But described this structure has a lot of drawbacks; The stressed maximum of its afterbody transmission (engagement driving between the second driver pinion e and the driven gearwheel f of output), tangential force (arrow points among Fig. 1) acts on the bolt 2, and the bonding crack when overload operation between case lid 3 and the casing 1 tends to occur oil leakage phenomenon; The bearing (ball) cover 8 carrying helical teeth axial forces of casing 1 both sides (among Fig. 2 shown in the arrow); Casing 1 longer both sides intensity is more weak, and when the clockwise and anticlockwise alternative frequency was high, the bonding crack generation resiliently deformable between case lid 3 and the casing 1 caused leakage of oil.In order to prevent two-way alternation active force, the artificer is the quite abundant heaviness of casing 1 design, and both having wasted steel has increased cost, and is chain huge to a lot of equipment that speed reducer must be installed mounting base that also becomes again.
The model utility content
The utility model provides a kind of compact structure, little, the lightweight twin shaft multi-stage speed-reducing of volume machine in order to solve deficiency of the prior art.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: twin shaft multi-stage speed-reducing machine, comprise casing, parallel rotation is located at input shaft and the output shaft on the casing, be fixed with input driver pinion and rotation on the described input shaft and be provided with at least one input duplicate gear, rotate on the output shaft and be provided with the output duplicate gear and be fixed with the driven gearwheel of output, the output duplicate gear equates with input duplicate gear number and the small gear of exporting duplicate gear is connected by meshing transmission with the gearwheel of inputting duplicate gear, the input driver pinion is connected by meshing transmission with the gearwheel of output duplicate gear, and the small gear of input duplicate gear is connected by meshing transmission with the driven gearwheel of output.
Described casing is made of vertically disposed two side box boards of intermediate frame and intermediate frame both sides, and input shaft and output shaft are automatically connected on two side box boards by bearing rotary, and described two side box boards outside is provided with bearing (ball) cover.
Described input shaft and the gear shaft structure that the input driver pinion is integrated are exported driven gearwheel key and are connected on the output shaft.
Adopt technique scheme, the input duplicate gear be connected duplicate gear and be connected with output shaft rotation with input shaft respectively by built-in bearing, realize the transmission of multistage different rotating speeds, input duplicate gear and output duplicate gear arrange respectively one, can realize three grades of decelerations; Arrange respectively two, can realize the Pyatyi deceleration; Arrange respectively three, can realize seven grades of decelerations; By parity of reasoning, and the increase along with input duplicate gear and output duplicate gear number can realize more multistage deceleration, makes speed ratio can reach 1:1000, or larger.
The utlity model has following characteristics and using value: 1. can be applicable to narrow space, need heavy duty, and be on the equipment that can't install of common speed reducer.2. can be applicable in the fields such as Aero-Space navigation and be starved of on the equipment of weight reduction.3. alternative super sized type speed reducer solves overweight can't the transportation, large-scale crane, the drawback that can't arrive, can't lift, for example be applied to large hydraulic engineering equipment, also less than planetary speed reducer volume, cost is also low, solves the hang-up of puzzling and hang for many years and do not separate in some field.4. alternative large speed ratio high pulling torque worm-gear speed reducer, (if worm reduction gear is the rotation high speed long time running that slides, worm screw can generate heat and grind burning), the utility model can not shut down long time running in 24 hours at a high speed and do not generated heat.5. if be inverted input shaft and output shaft, namely from the output shaft input power, the input shaft speedup can be applied on the wind-driven generator, and is higher than the mechanical efficiency of ordinary gear booster engine, the life-span is long, can increase generated energy.
The utility model application area is boundless, owing to compact structure, volume weight reduce, technique is simple and direct, can save lot of materials, time, human and material resources in a series of links such as production, transportation, makes it cost cutting, reaches the effect of low-carbon energy-saving.
