Abstract
The utility model discloses a flywheel for the cassette mechanism of a cassette recorder, comprising a capstan axle, a flywheel tape spool and sheet metals. The flywheel is characterized in that the number of the sheet metals is added so as to enlarge the rotary inertia of the flywheel, enhance the stability of the angular speed of the capstan axle of the cassette mechanism, and decrease wow and flutter to make a tape run homogeneously.
Description
The utility model is about a kind of improved cassette record machine core flywheel.
The cassette tape recorder movement is the tape transport of magnetic tape cassette.Its effect is to drive tape motion by belt pulley or gear drive, function such as finish recording, playback, F.F., rewinding, suspend, stop.Fig. 1 is the synoptic diagram of this class movement gear train, wherein 1 is the motor pulley that is connected with motor, motor pulley 1 is sleeved on flywheel 2 on the capstan 4 by belt drives, pinch roller 3 is pressed to capstan 4 under the effect of spring, under the friction force effect, tape 5 motions of driving between capstan 4 and pinch roller 3, in transmission process, flywheel 2 is except that decelerating effect, also should have good speed stabilizing effect,, obtain stable tape running speed to reduce the fluctuation of capstan 4 angular velocity, reduce the flutter of movement, improve recording playback sound performance.
Fig. 2 is the semisectional view of the flywheel of present this class movement, and wherein 6 is flywheel sheet metals, the 7th, and the flywheel tep reel, this structure is because moment of inertia is less, and wow and flutter is bigger, influences the performance of movement.
The purpose of this utility model provides the flywheel after a kind of the improvement, this flywheel need not improve the machining precision of transmission parts, only depend on the moment of inertia that strengthens flywheel can reduce the irregular influence of other moving component rotating speeds to the flywheel rotating speed, thereby reduce the angular velocity fluctuation of capstan 4, improve the wow and flutter performance of movement.
Design of the present utility model is the quantity that increases the flywheel sheet metal, strengthens Rotary Inertia of Flywheel, and capstan angular velocity is stable to make the tape walking speed even thereby make, and improves recording playback sound performance.
Accompanying drawing 3 has shown an embodiment of the present utility model, and wherein flywheel tep reel 7 is fitted on the capstan 4, and metal couple 6 is sleeved on the flywheel tep reel 8, and 8 of flywheel tep reels are sleeved on the flywheel tep reel 7.Owing to increased a sheet metal, increased the moment of inertia of flywheel 2, reduce the fluctuation of capstan 4 angular velocity, thereby reduced the wow and flutter of movement, improve the performance of movement.
Accompanying drawing 4 is another embodiment of the present utility model, and wherein metal couple 6 is divided in the both sides of flywheel tep reel 7, has played the same purpose with flywheel shown in the accompanying drawing 3.
Claims (1)
1, a kind of cassette record movement flywheel, by capstan 4, flywheel tep reel 7 and 8 and the sheet metal 6 that is sleeved on the tep reel form, it is characterized in that sheet metal 6 is two.
