Abstract

The utility model discloses a conical driving wheel of a fixed station at a driving shaft, which consists of a conical permanent magnet tube and a non-magnetic cone which are consolidated with each other; the permanent magnet tube is magnetized along the direction of a bus; a driven shaft is a splined shaft, the axes of which is parallel to the bus of a drive pulley; a disk shaped driven wheel is sheathed on the driven shaft which is capable of sliding at the shaft along the direction of the axes; the driven wheel comprises an arch permanent magnet block magnetized along the radial direction, a non-magnetic ring, a permanent magnet ring magnetized in the axial direction and a non-magnetic garland that are consolidated with each other; the arch permanent magnet block is alternatively contacted and consolidated along the peripheral polarity of the non-magnetic ring; or a plurality of arch permanent magnet blocks are embedded along the circumferential direction at equivalent intervals at the peripheral of the non-magnetic ring, therefore, the arch permanent magnet block is opposite to the conical permanent magnet tube of the driving wheel with the same polarity; a shifting fork consists of a fork and a permanent magnet block that are consolidated with each other; the clearance of the shifting fork is checked out of the driven wheel; the surface of the permanent magnet block which is opposite to the end surface of the permanent magnet ring of the driven wheel is parallel and opposite to the clearance of the same polarity of the end surface of the permanent magnet ring. The conical driving wheel of the fixed bench on the driving shaft has the advantages of simple structure, non-friction when changing the speed, and saving energy.

Description

Magnetic force stepless transmission

Technical field

The utility model relates to a kind of speed changer, particularly a kind of magnetic force stepless transmission.

Background technology

Prior mechanical buncher complex structure, principal and subordinate's wheel is in contact with one another and utilizes frictional drive, thereby need bigger steering force in the speed-change process, and the principal and subordinate takes turns phase mutual friction meeting and produces chatter, heating loss's energy in the speed-change process, and the principal and subordinate takes turns serious wear and the life-span weak point.

Summary of the invention

The utility model designs a kind of magnetic force stepless transmission, and purpose is the defective that overcomes existing machinery formula speed changer, simplified structure, life-saving.

The utility model is realized by following technical scheme.

Fixed station taper driving wheel on driving shaft, driving wheel be by taper pipe magnetic separator and non magnetic awl fixed composition, and pipe magnetic separator is along being that thickness direction magnetizes perpendicular to generatrix direction; Driven shaft is the spline axle, make the bus of the parallel axes of driven shaft in drive, overlap the disc driven pulley thereon, the bus septal space of driven pulley is parallel to the bus of driving wheel, the end face of driven pulley is perpendicular to the axis of driven shaft, driven pulley can slide along axis direction on axle, driven pulley is by the arc permanent magnets of radial magnetizing, non-magnetic ring, the permanent-magnetic clamp of axial charging, the fixed composition of non magnetic garland, the arc permanent magnets is fixed along the cylindrical circumference alternating polarity contact of non-magnetic ring, perhaps circumferentially uniformly-spaced inlay some arc permanent magnets, and make the arc permanent magnets relative with the taper pipe magnetic separator same polarity of driving wheel in the periphery upper edge of non-magnetic ring; Dial wooden fork by branch, permanent magnets is fixed forms, two permanent magnets be in respectively branch about the top of two teeth and just relative, dialling the wooden fork septal space is stuck in outside the driven pulley, permanent magnets magnetizes along the axis direction of driven pulley, and makes the permanent magnets face relative with the end face of the permanent-magnetic clamp of driven pulley parallel with the end face like pole septal space of permanent-magnetic clamp relatively.

Operation principle: described driving wheel and driven pulley produce the engagement torque by permanent magnetic gravitation, repulsion, realize transmission; Spur described group of wooden fork and move along the driven shaft axis, because the magnetic repulsion effect forces driven pulley to move along the driven shaft axis, the engagement radius on the platform taper driving wheel is along with variation, and driven pulley will obtain the continually varying rotating speed, thereby realizes infinitely variable speeds; If dial wooden fork at certain locking position, driven pulley will be obtained corresponding rotating speeds.

The effect that the utility model is useful is:

1, simple in structure;

2, no frictional drive, efficient height, life-span are long;

3, speed-change process frictional force very little, do not generate heat, required steering force is little, stable drive;

4, because by magnetic force noncontact transmission, so have overload protection function;

5, maintenance workload is little.
