Description

A kind of magnetic induction gear drive

The utility model relates to a kind of gear drive that interacts transferring power that utilizes between the magnet tooth piece.

Known gear drive is to drive follower by being meshing with each other between gear by adjacent driving wheel to rotate.Because of this driving mechanism, be that the engagement by tooth and tooth realizes, therefore in transmittance process, the contact of between cog must must cause the wearing and tearing of tooth, produces noise, and the loss of exerting all one's strength is big, and service life of gear is short.

The purpose of this utility model is to provide at the deficiencies in the prior art a kind of does not have that wearing and tearing, noise are low, long service life, the wide magnetic induction gear drive of application.

Goal of the invention of the present utility model is achieved by the following scheme: this magnetic induction gear drive, comprise driving shaft, driven shaft and be contained in driving wheel and follower on the diaxon respectively, described driving wheel is made up of the magnet tooth piece that is fixed on the pinion stand on the driving shaft and be fixed on the pinion stand, and described follower is made up of the magnet tooth piece that is fixed on the pinion stand on the driven shaft and be fixed on the pinion stand, the corresponding installation of magnet tooth piece on magnet tooth piece on the follower and the driving wheel, rely on interacting between the magnet tooth piece, do not having under the condition that contacts, mutually transferring power.

Magnet tooth piece on the described driven wheel can be by following several structural configuration: 1. separated type, bipolar to inhaling; 2. separated type, one pole are to inhaling; 3. separated type, one pole zero-bit are to scolding; 4. hasp type, suitable utmost point zero-bit are to scolding.Along utmost point zero-bit to the basis of scolding gear on, can establish an overburdening surface of contact respectively in magnet tooth piece both sides.

The utility model has the advantages that: 1. noise is low; 2. do not have wearing and tearing, need not lubricate, the power loss is little; 3. resiliency is good, and vibrations are little during transmission; 4. can skid automatically during overburdening, play a protective role; 5. long service life.It can be widely used in the mechanical transmission that various transmitted powers are little, the velocity ratio required precision is not high, is gear-driven new development.

Embodiment to the utility model is described further below in conjunction with accompanying drawing:

This magnetic induction gear drive mainly comprises driving shaft 1, driven shaft 2 and is contained in driving wheel and follower on the diaxon respectively, and driven wheel is made up of the

magnet tooth piece

5,6 that is fixed on the

pinion stand

3,4 on the corresponding shaft and is fixed on

pinion stand

3,4 respectively, and the magnet tooth piece 6 on the follower will be selected corresponding mounting type according to different transmission requirements with the magnet tooth piece 5 on the driving wheel, thereby by interacting between the magnet tooth piece, under the condition that does not have contact, reach the purpose of mutual transferring power.

Embodiment 1 (separated type, bipolar): as shown in Figure 1 to inhaling, the

magnet tooth piece

5,6 that is fixed on the

pinion stand

3,4 all is evenly distributed on the cylinder of pinion stand, and between the adjacent two tooth pieces that each is taken turns continuously every, and adjacent magnetic tooth is arranged opposite in polarity radially.

Its working principle is as follows: as shown in Figure 1, the S utmost point of tooth 5a is over against the N utmost point of driven gear teeth 6a in the driving wheel, and when driving wheel turned round, tooth 6a was under the gravitation traction of tooth 5a, opposite direction running, tooth 5b and tooth 6b, tooth 5c and tooth 6c thereupon ... running continuously under the traction of attractive interaction.As shown in Figure 2, when driving wheel turns round 1/2 flank of tooth, suppose that the follower original position do not change, at this moment the N utmost point of tooth 6a forces two crop rotations to be turned round relatively under the repulsion effect of the gravitation of the tooth 5aS utmost point and the tooth 5bN utmost point.As shown in Figure 3, when flank of tooth of driving wheel running, suppose that the follower original position do not change, at this moment, driving wheel have only two kinds possible, transfixion or skid, this kind no longer loss power of skidding can be used for the overburdening automatic safety device.As shown in Figure 4, when tooth 5a in the driving wheel and tooth 6a in the follower are in when separating stroke, their relative tooth 5c are in 6c and combine stroke, and their power equates, thus needn't worry pulling force when separating stroke of tooth 5a and tooth 6a, can the loss driving force.

Embodiment 2 (separated type, one pole are to inhaling) as shown in Figure 5,

magnet tooth piece

5,6 on driving wheel and the follower also all is evenly distributed on the cylinder of

pinion stand

3,4, but the adjacent two tooth pieces that each is taken turns has at interval, and each magnetic tooth is arranged consistent in polarity radially, and that the polarity between two-wheeled is arranged is opposite.Its transmission principle is to bipolar similar to inhaling, and difference is that one pole has only radial pull to inhaling structure.

Embodiment 3 (separated type, one pole zero-bit are to scolding), as shown in Figure 6, its tooth piece distribution situation is consistent with embodiment 2, and difference is that the polarity arrangement between two-wheeled is consistent.And its transmission principle is to bipolar similar to inhaling, and difference is staticly not change or when dallying, can reduce or eliminate radial pull or repulsion between two transmission shafts, thereby alleviate the wearing and tearing of bearing.

Embodiment's 4 (hasp types, suitable utmost point zero-bit is to scolding), as shown in Figure 7, its tooth piece distribute with full depth tooth gear teeth distributional class seemingly, polarity is opposite between each adjacent teeth of taking turns, its transmission principle is similar to embodiment 3, and difference is that the central point of homopolarity is relatively positive, and the magnetic force of magnet is directly acted on, thereby strengthened the transmission power of magnetic tooth, practical.

Embodiment 5 is on embodiment 4 basis, has set up overburdening surface of contact 7 in the both sides of magnetic tooth, and this surface of contact material selection wear resistance is good, intensity is high, to the insensitive material of magnetic, as making with stainless steel material.Its main effect be when preventing that super negative from bumping to the damage of magnetic tooth, thereby the magnetic tooth is played protection; When overburdening delivers, can be converted to Contact Transmission by contactless transmission in addition, its mechanical property is good to the similar resiliency of gear commonly used, when loading just often, can transfer the contactless transmission state automatically to again.Therefore this kind structure gear may be used on separated type, hasp type, on the kinds of drive such as gear Contact Transmission commonly used.
