Abstract
The invention discloses a novel transmission variable rectilinear motion mechanism. A variable frequency coil is arranged at the lower end of a hollow shaft. The outer circumference of the hollow shaft is provided with a fixed rotor. The hollow shaft is arranged on the upper surface of a machine body by a bearing. A lead screw is arranged in an inner thread of the hollow shaft. The outer circumference of the lead screw is provided with a sliding groove. A check plate is provided with the sliding groove. A rotation stop tongue is clamped on the upper surface in the sliding groove of the lead screw, so that the check plate is arranged on the upper surface of the machine body.
Description
Technical field
The present invention relates to a kind of transmission gear shift straight-line motion mechanism, particularly a kind of novel transmission gear shift straight-line motion mechanism.Belong to the mechanical transmissioning technology field.
Background technique
In machine-building and mechanical transmissioning technology field, often use straight-line motion mechanism, at present, realize that straight-line motion mechanism mainly adopts machinery type, pneumatic or hydraulic way.Adopt machinery type generally need pass through gear shift; Connecting rod or pinion and rack; Adopt pneumatic or hydraulic way then not only need be moved executive component cylinder or oil hydraulic cylinder; Also need stable source of the gas or hydraulic power simultaneously, all there is the defective that structural system is complicated, volume takes up room greatly, cost is higher and rate of fault is higher in above dual mode.
Summary of the invention
The objective of the invention is to: a kind of novel transmission gear shift straight-line motion mechanism is provided, overcomes the existing above-mentioned defective of existing straight-line motion mechanism.
Solving the technological scheme that its technical problem adopts is: a kind of novel transmission gear shift straight-line motion mechanism, and it is the lower end that is installed in hollow shaft by the variable ratio frequency changer coil, and a fixed rotor is installed on the cylindrical of hollow shaft; Hollow shaft passes through Bearing Installation on body; Leading screw is installed in the internal thread of hollow shaft, and the cylindrical of leading screw is provided with a chute, and check plate is provided with chute; Above the spline tongue is fastened in the chute of leading screw, with check plate be installed in body above.
Beneficial effect: it is less that the present invention has compact structure, the mechanism volume that takes up room; Simultaneously; Can control arbitrarily straight-line speed and direction; Automaticity is high, and it is complicated effectively to have overcome the existing train of mechanism of existing straight-line mechanism, the defective that volume takes up room greatly, cost is high and rate of fault is high.
