Abstract

The utility model discloses a new style machine transmission device, in particular to a permanent magnet turbine used for the transmission of the movement between two alternating shafts. The utility model is characterized in that rotating component worm rod and worm gear are all made of super magnetic materials. When the worm rod and the worm gear are engaged, tooth surfaces are not contacted, the engaged tooth surfaces of the worm rod and the worm gear are magnetized, and the worm rod and the worm gear are enabled to have same magnetic poles and polarity. In addition, a small groove is arranged on the worm rod, and balance magnetic pole teeth are arranged in the small groove. The permanent magnet turbine has big transmission ratio and small size without abrasion. The utility model does not need to be lubricated, and the mechanical efficiency is improved. By the use of the magnetic energy, input power is enabled to be smaller than output power. The utility model is a new power machine.

Description

Permanent magnet turbine

The utility model relates to a kind of mechanical transmission, not only is used for transmitting two motions between staggered.But also can be used as a kind of new power engine.

Worm gear in the domestic and international widely used worm drive machine selects for use tin bronze or gray cast iron to make at present, and worm screw selects for use carbon steel or alloyed steel to make.Advantages such as though this worm drive facility have compact structure, overall sizes is little, velocity ratio is big, velocity ratio is constant, stable drive.But it has a fatal shortcoming is exactly that efficient is low.When the worm screw active, efficient generally has only 0.7～0.8, have when pressing down, efficient has only 0.4, and in rotation process, relative sliding velocity is big between the flank of tooth, when conditions such as lubricated, heat radiation and lubricant oil keep clean are good inadequately, the flank of tooth easily produces gummed and wearing and tearing are accelerated, thereby damages the worm drive machine.Worm gear antifriction material manufacturing commonly used in addition, cost is higher.

The purpose of this utility model is to avoid above-mentioned deficiency of the prior art and provides between a kind of efficient height, the flank of tooth and do not contact, need not lubricate, can not produce gummed and wearing and tearing, and can make the power source novel permanent magnetic worm gear machine of input power less than output power.

The purpose of this utility model can reach by following measure: worm and worm wheel all select for use the superpower permanet magnetic material to make.Worm screw is processed into double end earlier, and then removes a stature with mechanical means.And after worm gear processes, also remove a circle tooth with the mechanical means compartment of terrain again, the tooth pitch of worm gear is increased.And when making worm and wheel meshing, their flank of tooth does not contact, but allows the mesh tooth face of worm and wheel magnetize, and makes that their pole polarity is identical (be all the N utmost point, or be all the S utmost point).

The purpose of this utility model can also reach by following measure: on the magnetic pole tooth of worm screw, the distance of the face width in every interval is left a sulculus, and the one side facing to the worm movement direction is installed a weight equalizer tooth opposite with the worm gear pole polarity in sulculus.

The purpose of this utility model can also reach by following measure: worm and worm wheel also can be made fabricated, only use the superpower permanet magnetic material on the gear ring of the teeth of worm screw and worm gear, and common iron are all used in inside.After assembling type worm screw, worm gear process, only teeth and gear ring are magnetized, make their pole polarity identical.

The drawing of accompanying drawing is described as follows:

Fig. 1 is a structural drawing of the present utility model.

Fig. 2 is the sectional view in magnetic pole tooth when engagement of worm and wheel.

The utility model is described in further detail below in conjunction with embodiment: worm screw (1) is enclosed within on the worm shaft (5), worm shaft (5) is fixed on the casing (2) by bearing (4) and bearing support (3) then, same worm gear (6) also is enclosed within on the worm-wheel shaft (7), and worm-wheel shaft (7) also is fixed on the casing (2) by bearing (4) and bearing support (3) then.Worm screw (1) and worm gear (6) all select for use ferro-aluminum boron superpower permanet magnetic material to make.For fear of the phase mutual interference of magnetic pole, worm screw (1) is processed into double end earlier, and then removes a stature with mechanical means.And after worm gear (6) processes, also remove a circle tooth with the mechanical means compartment of terrain again, and the tooth pitch of worm gear (6) is increased, guarantee the generation of effective torque.And during the engagement of worm screw (1) and worm gear (6), their flank of tooth does not contact, but allows the mesh tooth face of worm screw (1) and worm gear (6) magnetize, and makes that their pole polarity is identical (be all the N utmost point, or be all the S utmost point).When two magnetic pole tooths of worm screw (1) and worm gear (6) meshed, because the existence of helix angle, worm gear magnetic pole tooth (10) became worm screw (1) resistance to motion to the some in the reaction force of worm screw magnetic pole tooth (8).In order to offset or to weaken this partly resistance, just on worm screw magnetic pole tooth (8), the distance of the face width in every interval is left a sulculus, and the one side facing to worm screw (1) moving direction is installed a weight equalizer tooth (9) opposite with worm gear (6) pole polarity in sulculus.Worm gear magnetic pole tooth (10) will produce gravitation f1 and repulsion f2 to two faces of weight equalizer tooth (9) like this, and the direction of these two active forces sense of rotation with worm screw (1) basically is identical, can weaken even offset the resisting moment of worm screw (1).With the exception of this, worm gear (6) can also be made plane straight-tooth worm gear, worm screw (1) can be made the worm screw that local helix angle is a zero degree, and form is as the ladder in the winding staircase.In order to save expensive superpower permanet magnetic material, worm screw (1) and worm gear (6) also can be made fabricated, only on the gear ring of the teeth of worm screw (1) and worm gear (6), use the superpower permanet magnetic material, and nonmagnetic substance is all used in inside, after assembling type worm screw, worm gear process, only teeth and gear ring are magnetized, make their pole polarity identical.Because worm tooth and worm-gear tooth all use the superpower permanet magnetic material to make, and polarity is identical, the magnetic repulsion that produces when they mesh just constitutes the output torque of worm gear (6).Because of worm screw (1) is continuous spiral, so as long as the motion of worm screw (1) is continuous, the output torque that is produced by magnetic repulsion also is continuous.And can make input power under the reinforing function of magnetic field energy, and output power is increased, make this device become a kind of power machine.

The utility model has following advantage compared to existing technology: because worm and wheel when engagement, their flank of tooth can not contact with each other, so the flank of tooth can not produce gummed and wearing and tearing, does not need to lubricate yet. And this permanent magnet turbine improves greatly than the efficient of common worm gear machine. It also may make input under the reinforcement of magnetic field energy power is less than power output, thereby this permanent magnet turbine becomes a kind of new power machine.
