Abstract
The utility model discloses a special helical gear lead screw speed reducer for an elevator. The special helical gear lead screw speed reducer comprises a shell, a lead screw, a hollow threaded output shaft, an output shaft gear, a transmission cylindrical gear, a transmission gear, and an input cylindrical gear, wherein the input cylindrical gear is meshed with the transmission gear; the transmission gear is fixedly connected with the transmission cylindrical gear; the transmission shaft cylindrical gear is meshed with the output shaft gear; the hollow threaded output shaft is fixedly connected with the output shaft gear; the lead screw is meshed with the hollow threaded output shaft; the lead screw, the hollow threaded output shaft, the output shaft gear, the transmission cylindrical gear, the transmission gear and the input cylindrical gear are helical teeth. In the utility model, the helical gear is adopted to substitute the straight gear to increase the carrying capacity of the gears, meet safety requirement for a user, and meet requirements of port facilities through the lead screw lifting location. The special helical gear lead screw speed reducer is safe and reliable, and can meet the requirements of port elevators.
Description
Technical field
The utility model design speed reducer technical field, is specifically related to the special helical gear screw mandrel of a kind of lift speed reducer.
Background technique
In the 70-80 age in 20th century, speed reducer technology has a great development in the world, and combines closely with the development of new technology revolution.Require speed reducer will have some very high indexs in the place of different uses, the running lifting means at harbour, requirement speed reducer is safe and reliable, general speed reducer adopts traditional spur gear, because spur gear bearing capacity is limited, can not meet safety requirement, need difference because different user installs again, therefore input, output shaft, center are high and axial length will be according to user's requirement design.
Model utility content
For addressing the above problem, the utility model discloses the special helical gear screw mandrel of a kind of lift speed reducer, comprise: casing, screw mandrel, hollow thread output shaft, output shaft gear, transmission cylindrical gears, driving gear, input cylindrical gears, described hollow thread output shaft, output shaft gear, transmission cylindrical gears, driving gear, input cylindrical gears is all in casing inside, described input cylindrical gears engages with driving gear, described driving gear and transmission cylindrical gears are affixed, described transmission shaft cylindrical gears engages with output shaft gear, described hollow thread output shaft and output shaft gear are affixed, described screw mandrel engages with hollow thread output shaft.
Described hollow thread output shaft, output shaft gear, transmission cylindrical gears, driving gear, input cylindrical gears are all helical teeth.
In the utility model, screw mandrel, hollow thread output shaft, output shaft gear, transmission cylindrical gears, driving gear, input cylindrical gears are all helical teeth, have increased the bearing capacity of gear, have met the demand of user to safety.
Driven by motor input cylindrical gears in the utility model, through casing, inner transmission is slowed down, and by screw mandrel lifting location, has met the demand of harbour lifting means.
Owing to adopting technique scheme, the utlity model has following beneficial effect fruit:
1) safe and reliable;
2) meet the demand of harbour lift.
