Abstract
The invention discloses a special helical gear speed redactor which comprises an out shell, an input cylindrical gear, a first-stage transmission gear, a first-stage transmission cylindrical gear, a second-stage transmission gear, a second-stage transmission cylindrical gear, an output shaft cylindrical gear and an output shaft. The input cylindrical gear, the first-stage transmission gear, the first-stage transmission cylindrical gear, the second-stage transmission gear, the second-stage transmission cylindrical gear and the output shaft cylindrical gear are helical gears, and the output shaft and the input shaft are not on the same plane. The helical gears are used for replacing spur gears so as to guarantee safety, the structure meets the installation requirements of users, and the special helical gear speed redactor has the advantages of being safe and reliable, reasonable in structure and the like.
Description
Technical field
The present invention relates to speed reducer technical field, be specifically related to a kind of special helical speed reduction gear.
Background technique
Speed reducer is the separate transmission parts for reducing rotating speed, transferring power, increase torque.Retarder plays coupling rotating speed and transmitting torque between prime mover and working machine or actuator, and in modern mechanical, application is very extensive.
Tradition speed reducer generally adopts spur gear, although spur gear is made simple, because its structure causes bearing capacity limited, generally occurs that overload can cause very large loss, also due to the difference of user's installation requirements, general speed reducer can not meet each user's demand.
Summary of the invention
For addressing the above problem, the invention discloses a kind of special helical speed reduction gear, comprising: casing, input cylindrical gears, one-level driving gear, one-level transmission cylindrical gears, secondary transmission gear, secondary transmission cylindrical gears, output shaft cylindrical gears, output shaft, described input cylindrical gears, one-level driving gear, one-level transmission cylindrical gears, secondary transmission gear, secondary transmission cylindrical gears, output shaft cylindrical gears, output shaft is all in casing inside, described input cylindrical gears engages with one-level driving gear, described one-level driving gear and one-level transmission cylindrical gears are affixed, described one-level transmission cylindrical gears engages with secondary transmission gear, described secondary transmission gear and secondary transmission cylindrical gears are affixed, described secondary transmission cylindrical gears engages with output shaft cylindrical gears, and described output shaft cylindrical gears and output shaft are affixed, described input cylindrical gears, one-level driving gear, one-level transmission cylindrical gears, secondary transmission gear, secondary transmission cylindrical gears, output shaft cylindrical gears is all helical teeth.
Described output shaft and input shaft be not in same level.
The present invention adopts helical gear to replace traditional spur gear, has increased the bearing capacity of gear, has reduced the friction of gear, makes speed reducer after working long hours, keep very high Security.
The present invention is arranged on different level according to user's installation requirements by input shaft and output shaft, has met user's demand.
Owing to adopting technique scheme, the present invention has following beneficial effect fruit:
1) bearing capacity is large, safe and reliable;
2) meet user's installation requirements.
