It is left-handed, the number of teeth 24.
The major parameter of double reduction worm screw 32 are as follows: axial module 1.4077, normal module 1.4,20 ° of pressure angle, spiral
6 ° of angle, left-handed, head number 1.
The parameter of output gear 4 is axial module 1.4077, and normal module 1.4 is 20 ° of pressure angle, 6 ° of helical angle, left-handed,
The number of teeth: 27.
The prior art the problem is that: motor export braking moment it is smaller, generally 30-40N.m；The loss of electric machine
Larger, electric efficiency is 20% hereinafter, output power is less than 20W；Rotor copper consumption is 100g-110g；Motor turns
Sub- axis and shell are longer, and axis reaches 162.5mm, and shell reaches: 112mm, motor total weight reach: 2148g, in addition, due to four
Head worm spiral angle is larger, and lead is also larger, causes processing difficulties, the bad processing of fly cutter in process, and four-head indexes not
Easily uniformly, cause machining accuracy poor, motor has an abnormal sound, worm face width very little, intensity difference, easily damages and will appear shaving phenomenon.
Utility model content
The utility model is according to the above deficiency, provide a kind of pedal motor reduction assemblies, to the progress of some of parameters
It improves.
The technical solution of the utility model is:
A kind of pedal motor reduction assemblies, comprising:
Shell；
Motor is mounted in shell；

14.28 °, it is left-handed.
The axial module of the one-stage gear is 1.28985, and normal module 1.25, pressure angle is 10 °, and helical angle is
It is 14.28 °, left-handed, the number of teeth 20.
The pressure angle of the output gear is 15 °.
In order to reduce cost, while noise is reduced, the teeth portion of the one-stage gear is made of plastics.
In order to reduce cost, transmission efficiency is improved, the output gear is copper-clad iron construction.
Triple start worm becomes easy processing, indexing is uniformly and precision easily guarantees that the facewidth broadens, by force since helical angle becomes smaller
Degree increases, and after worm accuracy guarantees, avoids the generation of motor abnormal sound.Double reduction reduces pressure angle, makes reduction train
The transmission efficiency of system gets a promotion, and actual measurement electric efficiency is 25%, and power reaches 23W, since reduction ratio improves, makes the defeated of motor
Torque becomes larger out, and braking moment reaches 40-48N.m, and materials upper rotor part stator length all shortens, rotor length 154mm, stator
Length is 96mm, rotor copper consumption 80g or so, and motor total weight is 1961g, and the cost of the utility model obviously compares the prior art
It is low.
It should be noted that in general, number of threads is more, transmission efficiency is higher, but since there is in processing
The reasons such as difficulty, reduce transmission efficiency instead, and the utility model reduces number of threads, and handling ease is realized, improve
Transmission efficiency breaches conventional theory.
The utility model is saved with structurally reasonable, at low cost, materials, light-weight, noise is small, easy processing, and output torque is big,
The low beneficial effect of power consumption.
