Description
Technical field
The present invention relates to a kind of hollow shaft screw body, particularly a kind of transmission straight line motion hollow shaft screw body, belongs to mechanical transmissioning technology field.
Background technique
In machine-building and mechanical transmissioning technology field, often use straight-line motion mechanism, at present, realize straight-line motion mechanism and mainly adopt machinery type, adopt machinery type generally need to pass through gear shift, connecting rod or pinion and rack, also need stable source of the gas or hydraulic power simultaneously, so current transmission straight line motion hollow shaft screw body exists complex structure, volume to take up room greatly, the defect that cost is high, rate of fault is high.
Summary of the invention
The object of the invention is to; A kind of transmission straight line motion hollow shaft screw body is provided, overcomes the existing above-mentioned defect of existing transmission straight line motion hollow shaft screw body.
The technical solution adopted for the present invention to solve the technical problems is: a kind of transmission straight line motion hollow shaft screw body, and it is comprised of mechanism body, frequency conversion coil, rotor, bearing, hollow shaft, leading screw, spline plate and spline tongue, at hollow shaft screw body, there is a hollow shaft, on cylindrical at hollow shaft in base inner, rotor is installed, hollow shaft is arranged on above support by bearing, in the hollow inner circle of hollow shaft, be provided with internal thread, above the cylindrical of leading screw, be provided with the outside thread with the hollow inner circle same size of hollow shaft, leading screw is through in the internal thread that screws into hollow shaft on it, on the cylindrical of leading screw, be provided with the spline tongue parallel with its axis, there is a hole similar to leading screw sectional shape the centre of spline plate, its outstanding spline tongue is fastened in the chute of leading screw, spline plate by bolt be arranged on support above.
Working principle of the present invention is: by mechanism body, frequency conversion coil, rotor, bearing, hollow shaft, form variable-frequency motor, because the mode by frequency conversion can be controlled arbitrarily the rotating speed of rotor, and rotor is connected and fixed with hollow shaft, hollow shaft is arranged on above support by bearing, so hollow shaft has the rotating speed identical with rotor, due to the restriction of check plate stop tongue to screw mandrel, screw mandrel cannot be rotated, so when hollow shaft rotates, leading screw just moves along its axis.
Beneficial effect: it is little that the present invention has advantages of that compact structure, mechanism take up room, has effectively overcome the existing complex structure of existing transmission straight line motion hollow shaft screw body, volume takes up room greatly, the defect that cost is high, rate of fault is high.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, structure of the present invention is further described.
Fig. 1 is structure principle chart of the present invention.
Shown in figure: 1, mechanism body; 2, frequency conversion coil; 3, rotor; 4, bearing; 5, hollow shaft; 6, leading screw; 7, spline plate; 8, spline tongue.
