Abstract

The utility model relates to a hand-operated miniature recorder motor which is used for continuously output by constant torque after mechanical energy provided by manpower is stored. A disc type spring is used as an energy storage element. Constant torque is outputted through the combination of the rotary direction of the spring, a speed stabilization sheet and a speed adjusting device. The utility model can be used as a motor of a miniature recorder and a record player.

Description

Hand-operated miniature recorder motor

The utility model a kind of mechanical energy that will manually provide is provided stores the manually operated type micro recorder motor that export continuously with more constant torque the back.

At present, micro recorder, walkman are used by increasing people with advantages such as its volume are little, in light weight, easy to carry.But micro recorder, walkman use dryelement cell as the energy, drive motor, and energy charge is fast, needs the frequent battery of changing.Also uneconomical economically.

The purpose of this utility model just provides and a kind ofly exports that torque is comparatively constant, the motor of the micro recorder of manual energy storage.

The utility model is achieved through the following technical solutions:

As energy-storage travelling wave tube, constitute stored energy mechanism with disc spring (for example clock clockwork spring), simultaneously, adopt arrangements for speed regulation, make the more constant torque of transmission shaft output by the rotation direction combination of spring and the end of speed stabilizing sheet connection adjacent springs.

Be described in further detail below in conjunction with accompanying drawing:

Support (3) supports all elements as the pedestal of motor.It is foursquare port that the input end of transmission shaft (1) has cross section, is convenient to the suit handle, and its output terminal joins with output gearwheel (15).Speed governing nut (2), ring washer (4), governor spring (5) and packing ring (6) are enclosed within on the transmission shaft (1) successively, form arrangements for speed regulation.Stored energy mechanism then mainly is made up of left-handed disc spring (8,14), dextrorotation disc spring (10,12), speed stabilizing sheet (9,13) and movable axle sleeve (11) etc.These elements all are placed on the transmission shaft (1).Wherein driving sleeve (7) is connected with transmission shaft (1) by key.The head end of left-handed disc spring (8) (spring inner ring end is a head end, and the outer ring end is a tail end, down together) is affixed with driving sleeve (7).The end of left-handed disc spring (8) is connected by speed stabilizing sheet (9) with the end of dextrorotation disc spring (10).The head end of the head end of left-handed disc spring (10) and dextrorotation disc spring (12) all is fixed on the movable axle sleeve (11).The end of dextrorotation disc spring (12) is connected by speed stabilizing sheet (13) with the end of left-handed disc spring (14).The head end of left-handed disc spring (14) is fixed on the support (3).Belt wheel (small gear) is arranged on the fulcrum (16).

As shown in Figure 1, transmission shaft (1) is reversed input torque by counterclockwise (from the transmission shaft input end).The head end of left-handed disc spring (8) is passed in torque by the driving sleeve (7) that is connected with transmission shaft (1), and tightened gradually, because the head end of spring (8) is connected by speed stabilizing sheet (9) with the head end of spring (10), when spring (8) is tightened, go up one of generation at speed stabilizing sheet (9) and press anti-clockwise moment of torsion, be delivered on the spring (10), it is pressed tension clockwise.In like manner, constantly press the counterclockwise input torque, energy is delivered among spring (12), (14), till all springs are stored up full energy gradually.During the output torque, according to the reversed order of input torque, make transmission shaft (1) by rotating clockwise, final torque passes to belt wheel (small gear) (17) by the terminal output gearwheel (15) of transmission shaft (1).Speed stabilizing sheet (9,13) connects two spring actions except that rising, because two springs adopt different rotation direction combinations, under torque, produces axial pressing force, suppresses torque, plays the speed stabilizing effect.The decrement of speed governing nut (2) the can regulate governor spring (5) in the rotating speed regulating device fro, thus the axial pre tightening force of driving sleeve (7) regulated, and reach the purpose of governing speed.

The utility model is simple in structure, and is economical and practical.

Claims (2)

1, a kind of manually operated type micro recorder motor, have output gearwheel (15), transmission shaft (1) is positioned on the support (3), all energy-storage travelling wave tubes and arrangements for speed regulation all pass through transmission shaft (1) combination, it is characterized in that constituting stored energy mechanism by disc spring (9,10,12,14) by speed stabilizing sheet (9,13) and movable axle sleeve (11).

2, a kind of manually operated type micro recorder motor according to claim 1 is characterized in that two every group of the disc springs (8,10,12,14) of stored energy mechanism and rotation direction is opposite separately.
