Abstract
A novel damping noise reduction device belongs to the technical field of noise reduction of a stepping motor driving rotating disk mechanical transmission system. The mechanical noise reduction device is characterized in that a mechanical noise reduction device which provides initial pressure for the rotating disc (5) and generates damping force is arranged between the base (1) and the rotating disc (5), one end of the rotating arm (3) is fixed on the base (1), the other end of the rotating arm is fixed with the friction wheel (4), the friction wheel (4) is tightly pressed on the side surface of the rotating disc (5) through the torsion spring (2) between the base (1) and the rotating arm (3), and therefore fit clearance errors among transmission gears can be reduced, and noise is reduced. Has the advantages of simple structure, low cost, convenient operation, small occupied space and the like.
Description
The utility model is a kind of novel damping noise-decreasing device, relates to the technical field that reduces step motor drive rotating disk machine driven system noise.
Use rotating disk to luminous flux, density, quality, when volume is regulated at precision instrument, this roating plate system, realized continuously or the clearance-type circular motion by one or more levels gear drive by stepping motor, thereby realizes the adjusting of correlative.The weak point that exists during instrument uses is: every adjusting once, the control system drive stepping motor rotate once, and driven gear rotates.According to the variation of Control Parameter, stepping motor rotation integer step or half-integer step, because gap error can produce bigger noise, influence is used between travelling gear.
For addressing this problem, common way is to select stepping motor preferably for use, increases the machining accuracy of gear and axle system; Select different materials between the gear that is in contact with one another for use.But to large-scale precision instrument, this has increased cost greatly, has increased assembly difficulty, and effect is undesirable.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art and a kind of novel damping noise-decreasing device is provided, and can reduce the noise that stepper motor driven roating plate system produces because of the gap error between travelling gear effectively.
The purpose of this utility model can reach by following measure: novel damping noise-decreasing device, stepping motor is fixed on the pedestal, its motor shaft connects a pair of travelling gear, wherein a gear is connected on the axle, one end of axle is fixed with rotating disk, the other end is connected on the pedestal by bearing, between pedestal and rotating disk, be a mechanical noise-decreasing device that provides initial pressure to rotating disk and produce damping force.
The purpose of this utility model can also reach by following measure: in the mechanical noise-decreasing device, an end of pivoted arm is fixed on the pedestal, and the other end is fixed a friction pulley, and by the torsion spring between pedestal and the commentaries on classics stern, friction pulley is pressed on the outer garden face of rotating disk; Friction pulley is a rubber friction wheel.
Accompanying drawing is the utility model structure chart.
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in the figure: novel damping noise-decreasing device is that between pedestal and rotating disk one provides initial pressure to rotating disk and produces the mechanical noise-decreasing device of damping force.Stepping motor (10) is fixed on the pedestal (1), its motor shaft connection gear (9), gear (8) is engaged with, gear (8) is connected on the axle (6), one end of axle (6) is fixed with rotating disk (5), the other end is connected on the pedestal (1) by bearing (7), and an end of pivoted arm (3) is fixed on the pedestal (1), and the other end is fixed a rubber friction wheel (4), by the torsion spring (2) between pedestal (1) and the pivoted arm (3), friction pulley (4) is pressed on the periphery of rotating disk (5).
When the stepping motor (10) that is fixed on the pedestal (1), driven gear (9) and the gear (8) that is engaged with rotate, and then driving and gear (8) rotating disk (5) on same axle (6) is when rotating, friction pulley (4) is given (5) external force of rotating disk (F) by torsion spring (2), eliminated the gap error between the engagement of travelling gear (9) and gear (8), make system motion steady, noise is little.
The utility model is compared prior art and is had following advantage:
The utility model only needs at the support that stepper motor is installed a damping to be installed and subtracts the friction pulley device of making an uproar, With a torsion spring to friction pulley and rotating disc initial pressure, reducing the cooperation gap error between travelling gear, its Simple in structure, with low cost, easy to operate, it is little to take the space. Owing to be mechanically to outside one of the rotating disc Pressure has no effect to the control system of stepper motor.
Claims (3)
1, novel damping noise-decreasing device, stepping motor (10) is fixed on the pedestal (1), its motor shaft connects and gear (8) meshed gears (9), on the axle (6) gear (8) is arranged, one end of axle (6) is fixed with rotating disk (5), the other end is connected on the pedestal (1) by bearing (7), it is characterized in that between pedestal (1) and the rotating disk (5), is the mechanical noise-decreasing device initial pressure being provided for rotating disk (5) and producing damping force.
