The model utility content
The purpose of the utility model is to overcome the defective that exists in the existing technology, and a kind of two-stage umbrella gear speed reducer is provided, and transmission efficiency is high, and driving torque is big, stable drive, and noise is low, good combination property.
For realizing above-mentioned purpose; The technological scheme of the utility model is a kind of two-stage transmission speed reducer of design; Said retarder comprises casing, input shaft and output shaft; It is characterized in that, between said input shaft and output shaft, be provided with intermediate propeller shaft, on said intermediate propeller shaft, be provided with passive umbrella gear of one-level transmission and secondary transmission driving bevel gear; The passive umbrella gear of said one-level transmission is meshed with one-level transmission driving bevel gear on the input shaft, and said secondary transmission driving bevel gear is meshed with the passive umbrella gear of secondary transmission on the output shaft; Said intermediate propeller shaft, input shaft and output shaft are supported on the said casing through radial thrust bearing respectively, and the external part of said input shaft and output shaft lays respectively at a side of casing or relative both sides.
All utilize umbrella gear, through rational deployment, accomplish the double reduction transmission, simple in structure, transmission efficiency is high, and driving torque is big, stable drive, and noise is low, good combination property.Through regulating the relative number of teeth of active and passive umbrella gear, conveniently adjusted deceleration ratio satisfies application requirements.
In the utility model:
Be set with the oil removal cover on the output shaft in casing, make lubricant oil and output shaft isolated, solved the difficult problem of speed reducer product output shaft leakage of oil well, also improved greasy property, reduce wear, reduce noise.
Output shaft is designed to vertical failing, and intermediate propeller shaft is designed to horizontal axis, and input shaft can be a vertical shaft, also can be horizontal axis.Compact structure, the occupation of land space is little, and convenient in application also makes things convenient under some limited special occasions environment and installs.As required, can select the mounting type of adapted motor flexibly, all can putting installation, underlying installation and horizontal installation on the motor.Usually, motor comes drive speed reducer through belt pulley, and the belt pulley of transmission can be realized once elementary deceleration, thereby can make the utility model accomplish three grades of decelerations.
The passive umbrella gear of one-level transmission is installed on the intermediate propeller shaft through drive sleeve, can realizes the clutch operation, make things convenient for commercial Application.
Active and passive umbrella gear of one-level transmission and the active and passive umbrella gear of secondary transmission are placed respectively in two casings, and intermediate propeller shaft is formed by two sections, respectively has one section in two machines are bright, and two sections intermediate propeller shafts are connected by drive sleeve.Be convenient to make, install, debug and maintenance.
The advantage and the beneficial effect of the utility model are: this two-stage transmission speed reducer, and simple and compact for structure, transmission efficiency is high, and driving torque is big, stable drive, noise is low, and good combination property is beneficial to and applies.
