Abstract
The utility model discloses a speed reduction gear with low noise and long service life, and an existing speed reduction gear has certain boundedness on the reduction ratio and the transmission efficiency, large power consumption, large noise, large volume, short service life and high maintaining cost. The speed reduction gear comprises a gear box (1), wherein an input shaft (5) of the gear box is provided with a driving bevel wheel (6) which is meshed with a driven bevel wheel (7); the driven bevel wheel (7) is installed on a driving shaft (2); the driving gear (8) installed on the driving shaft is meshed with a driven gear (9); the driven gear is installed on a driven shaft (3); and a gear (10) installed on the driven shaft is meshed with an output gear (11) installed on an output shaft (4); and the input shaft, the driving shaft, the driven shaft or/and the output shaft are provided with thrust bearings. The product is beneficial to speed reduction of motor and mechanical drive.
Description
Technical field:
The speed reducer that the utility model relates to a kind of low noise, high working life belongs to mechanical manufacturing field.
Background technique:
The old-fashioned speed reducer of existing tradition adopts cycloidal-pin wheel formula, spiral bevel gear or worm and gear reducing transmission structure mostly, reduction speed ratio and transmission efficiency have certain narrow limitation, power consumption is big, noise is big, volume is big, working life is short, maintenance and repair expense height, particularly food machinery can not satisfy manufacturing technique requirent.
Summary of the invention:
The purpose of this utility model provides the speed reducer in a kind of low noise, high working life, can reduce the between cog friction by one-level helical gear, two groups of secondary gears and thrust-bearing, thereby improve transmission efficiency, has prolonged working life, utilizes fan for cooling.
Above-mentioned purpose realizes by following technological scheme:
The speed reducer in low noise, high working life, its composition comprises: gear-box, on the input shaft of described gear-box active oblique gear is installed, described active oblique gear and the engagement of passive helical gear, described passive helical gear is installed on the driving shaft, driving gear of installing on the described driving shaft and driven gear engagement, described driven gear is installed on the driven axle, gear of installing on the described driven axle and the output gear engagement that is installed on the output shaft, described input shaft, driving shaft, driven axle are or/and be equipped with thrust-bearing on the output shaft.
The speed reducer in described low noise, high working life, described input shaft, driving shaft, driven axle and output shaft are installed in the described gear-box by radial bearing respectively, on the described input shaft fan is housed, the crown of described active oblique gear, described passive helical gear and described gear partly has the oblique angle.
Beneficial effect:
1. the utility model adopts tooth, number of poles to optimize matching design, cooperate Parameter Optimization to improve location torque by teeth groove, the gear friction noise that has reduced the location torque of speed reducer system effectively and caused thus, the radial bearing at while driving shaft of the present utility model, driven axle and output shaft two ends, can reduce the radially friction of end ring, thereby reduce noise.
2. the crown of driving gear and driven gear partly has the oblique angle, can reduce the between cog friction, thereby improve transmission efficiency, has prolonged working life.
3. the fan on the input shaft of the present utility model can improve radiating condition, cools off gear, helps the proper functioning of solid lubrication fat.
4. compact structure of the present utility model, bulk volume is little, than the old-fashioned speed reducer volume-diminished 50% of tradition; The teeth groove gap is more reasonable, dwindles 50% than the old-fashioned reducer gear of tradition; The efficient height improves 80% than the old-fashioned deceleration body of tradition rated efficiency, thereby has reduced whole cost.
5. because the utility model is to adopt one-level helical gear and secondary gear reduction of speed, and reduction speed ratio can reach 1000/35, machinery driving efficiency is up to more than 98.
Description of drawings:
Accompanying drawing 1 is the structural representation of this product.
Accompanying drawing 2 is schematic representation that the crown of driving gear partly has the oblique angle.
Embodiment:
Embodiment 1:
Low noise, the speed reducer in high working life, its composition comprises: gear-box 1, active oblique gear 6 is installed on the input shaft 5 of described gear-box, described active oblique gear and 7 engagements of passive helical gear, described passive helical gear is installed on the driving shaft 2, driving gear of installing on the described driving shaft 8 and driven gear 9 engagements, described driven gear is installed on the driven axle 3, the gear of installing on the described driven axle 10 and output gear 11 engagements that are installed on the output shaft 4, described input shaft, driving shaft, driven axle is or/and be equipped with thrust-bearing 13 on the output shaft.
Embodiment 2:
The speed reducer in described low noise, high working life, described input 5, driving shaft 2, driven axle 3 and output shaft 4 are installed in described gear-box 1 the inside by radial bearing 12 respectively, and thrust-bearing 13 is equipped with in described radial bearing inboard.Wind 14 is housed on the described input shaft.On the axle fan is housed, the crown of described active oblique gear, described passive helical gear and described gear partly has the oblique angle.
Working procedure:
During the utility model work, input shaft is connected with motor, and by its rotation of driven by motor, driving driving shaft by active oblique gear and passive helical gear rotates, driving driven axle by driving gear and driven gear rotates, drive output shaft by driving gear and driven gear and rotate, thereby realized reduction of speed.
