Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The present embodiment proposes a kind of high-efficient low-noise transmission system, specifically with the transmission system be applied to cook's machine on be
Example illustrates, as shown in Figure 1 and Figure 2, including head 30（The head of cook's machine is referred specifically to, certain cook's machine further includes engine base 10
With fuselage 20 etc.）, direct current generator 50, transmission mechanism and stirring hook 40, transmission mechanism is located in head 30, head 30 include head
Main body 31 and the nose cover 32 below crosshead body 31, transmission mechanism includes level-one belt wheel transmission mechanism 60, main shaft 70, two
Grade transmission gear 80, ring gear 90 and eccentric gear 100；Main shaft 70 and the driven pulley 61 in level-one belt wheel transmission mechanism 60 are same
Axis is connected, and main shaft 70 is mounted on by bearing 110 and bearing block 120 on the shell of crosshead body 31；Secondary transmission gear 80
And nose cover 32 and main shaft 70 is coaxial is connected, ring gear 90 be connected on bearing block 120 by way of screw fastening and with master
Axis 70 is coaxially disposed, and eccentric gear 100 is mounted on the inner surface of nose cover 32 and the connection of its gear shaft is located under nose cover 32
The stirring of side hooks 40, and eccentric gear 100 is engaged with secondary transmission gear 80 and ring gear 90 simultaneously.
The present embodiment high-efficient low-noise transmission system, power train process are：Direct current generator 50 rotates, and passes through level-one belt wheel
Transmission mechanism 60 carries out primary speed-down, and main shaft 70 is rotated with driven pulley 61, then drives secondary transmission gear 80 and nose cover 32
Rotation, eccentric gear 100 are engaged with secondary transmission gear 80, then secondary transmission gear 80 constitutes two level with eccentric gear 100 and subtracts
Speed, secondary transmission gear 80 transmits torque to eccentric gear 100, while eccentric gear 100 is mounted on nose cover 32, nose cover
32 drive rotation with coaxial be connected of main shaft 70 by main shaft 70, then eccentric gear 100 carries out public affairs while rotation with nose cover 32
Turn, and eccentric gear 100 is engaged with ring gear 90 so that internal gear 90 plays guiding and balance to the rotation of eccentric gear 100
Effect, so forms planetary gear system, and then realizes the eccentric gear axis of connection stirring hook 40 while realizing rotation
It revolves round the sun around main shaft 70, completes knead dough, the functions such as beat eggs, stir.Due to selecting direct current generator 50, direct current generator rotating speed itself to be less than
The alternating current generator and torque of output is big, then be not necessarily to be arranged as the prior art multi-stage speed-reducing can be only achieved stirring hook 40 needed for turn
The torque of speed, then compared with prior art, the present embodiment cook's machine, transmission mechanism is simple in structure, overall efficiency is high, more energy efficient, passes
Motivation structure is simple in structure so that complete machine noise reduces；In addition, ring gear 90 is only served without transmitting torque to eccentric gear 100
The effect for being oriented to and being balanced, then ring gear 90 is without metal gear ring, avoid eccentric gear 100 and ring gear 90 it
Between rigid contact improve complete machine service life to reduce the damage to tooth form, reduce after-sales service cost.Preferably, originally
Ring gear 90 selects nylon ring gear in embodiment, is realized under the premise of meeting use intensity non-rigid with eccentric gear 100
Contact.
Further, direct current generator 50 is vertical upward, i.e., direct current generator 50 is vertically arranged and its output shaft upward, specifically set
It sets inside the fuselage 20 of cook's machine, so that level-one belt wheel transmission mechanism 60 is laterally arranged in head 30, integral structure layout is made to close
It manages, is compact, occupying little space.
Preferably, direct current generator 50 is permanent magnet DC motor, or selects other types direct current generator, and the present embodiment is to this
It is not particularly limited.
For level-one belt wheel transmission mechanism 60, it is arc tooth synchronous belt, phase to select synchronous belt drive mechanism, synchronous belt 63
The tooth form of its driving pulley 62 of ground and driven pulley 61 is answered to correspond to circle-arc tooth, arc tooth synchronous belt transmission efficiency, transmission ratio
Accurately, fricton-tight, steady, vibration can be absorbed, noise is small, further decreases complete machine noise.
Bearing 110 selects deep groove ball bearing, and nylon washer is provided between bearing block 120 and the shell of crosshead body 31
130, make to realize flexible connection between bearing block 120 and crosshead body 31, reduces complete machine oscillation.
