The utility model is characterized in that a drive gear (3) which is engaged with a driven gear (5) is arranged on an input shaft (2), the driven gear (5) is arranged at the end part of the worm screw (6) to form a first level drive, the worm screw (6) is engaged with a worm wheel (7) to form a second drive, a gear (8) which is engaged with a big output gear (9) is arranged on a shaft of the worm wheel (7), the big output gear (9) is arranged on an output shaft (10) to form a third drive, the drive gear (2), the driven gear (5), the gear (8) and the big output gear (9) are hard tooth surface gears, the worm screw (6) is a circular arc tooth worm screw, the worm wheel (7) is a circular arc tooth surface worm wheel, and the output shaft (10) can be a hollow shaft. The utility model has the advantages of compact structure, small size, big torque force and high drive efficiency. The drive ratio of the utility model is in a range of 7: 1-611: 1. The utility model can be used on the drive fields of light industries, chemical industries, food industries, building industries, print packing industries, tobacco feed machines, environmental projects, etc.
Description
Technical field
The utility model relates to the machinery that slows down, and particularly is fit to the large speed ratio speed reducer of SW series.
Background technique
Turbine and worm decelerator in the past all is single-stage driving structures, comprises shell, input shaft, worm gear, worm screw, bearing and output shaft, has only a kind of velocity ratio 180: 1; Defectives such as exist torque force little, velocity ratio is low, and Applicable scope is little.
The model utility content
The purpose of this utility model is at above-mentioned defective, and a kind of large speed ratio speed reducer is provided.
The technical solution of the utility model is that driving gear (3) and driven gear (5) engagement are installed on input shaft (2), and driven gear (5) is installed in worm screw (6) end and constitutes the one-level drive mechanism; Worm screw (6) and worm gear (7) engagement constitute the secondary drive mechanism; Gear (8) and output gearwheel (9) engagement also are installed on worm gear (7) axle, and output gearwheel (9) is installed on the output shaft (10), constitutes three grades of drive mechanisms.
Said driving gear (3), driven gear (5), gear (8) are hardened face gears with output gearwheel (9); Worm screw (6) is the circle-arc tooth worm screw, and worm gear (7) is the circular-arc tooth surface worm gear.
Said output shaft (10) is a hollow shaft.
Said velocity ratio is 7: 1～611: 1.
The utility model has the advantages that novel right angle speed reduction gearing by secondary gear slows down and worm and gear is formed; Adopt the worm gear level to have high reduction speed ratio, the low advantage of noise during operation; Adopt gear stage to have bearing capacity and reach stable drive and transmission efficiency height greatly, constitution optimization is reasonable, and Applicable scope increases; Be widely used in transmission fields such as light industry, food, beer beverage production line, chemical industry, building, printing packaging, tobacco machine, feed manufacturing machine, environment-friendly engineering.
Description of drawings
Fig. 1 is the utility model sectional structure chart.
Embodiment
Further describe embodiment below in conjunction with accompanying drawing.
With reference to Fig. 1,1-shell, 2-input shaft, 3-driving gear, 4-bearing, 5-driven gear, 6-worm screw, 7-worm gear, 8-gear, 9-output gearwheel, 10-output shaft.As shown, input shaft (2) is installed in the shell (1), driving gear (3) is installed on it, driven gear (5) is installed in worm screw (6) right part, and driving gear (3) and driven gear (5) engagement constitute the one-level transmission; Worm screw (6) two ends are installed on the shell (1), and two axial ends all is equipped with bearing (4), worm screw (6) and worm gear (7) engagement, the transmission of formation secondary; Gear (8) and gearwheel (9) engagement that is installed on the output shaft (10) are installed on worm gear (7) axle, constitute three grades of transmissions.More than be at improvement innovation from the worm-gear speed reducer of German import, the whole casing volume still is 140 * 180 original * 220mm, structure is very compact, increased velocity ratio, improved driving torque power, in order to improve the wear-resisting property of gear, adopt hardened face gear, just driving gear (3), driven gear (5), gear (8) they all are to adopt hardened face gear with output gearwheel (9); And worm screw (6) employing circle-arc tooth worm screw, worm gear (7) adopts the circular-arc tooth surface worm gear, improves Transmission bearing, has also improved efficient.Output shaft (10) can be a solid shaft, also can be hollow shaft.Through above-mentioned improvement, gear range expands as 7: 1～and 611: 1, become three grades of transmissions from original one-level transmission, make applicability better, be more suitable for the user and close middle use at various field boundarys.
Claims (4)
1, large speed ratio speed reducer, comprise shell, input shaft, worm gear, worm screw, bearing and output shaft, it is the single-stage driving structure, it is characterized in that being equipped with on input shaft (2) driving gear (3) and driven gear (5) engagement, driven gear (5) is installed in worm screw (6) end and constitutes the one-level drive mechanism; Worm screw (6) and worm gear (7) engagement constitute the secondary drive mechanism; Gear (8) and output gearwheel (9) engagement also are installed on worm gear (7) axle, and output gearwheel (9) is installed on the output shaft (10), constitutes three grades of drive mechanisms.
