Abstract

The utility model relates to a mechanism for driving inner and outer members to reversely rotate by a single motor, which is characterized in that an inner rotating member (9) is fixedly connected with a gear II (5), an outer rotating member (10) is fixedly connected with a synchronizing wheel II (8), the gear II (5) is engaged with a gear I (4) in parallel, the synchronizing wheel II (8) is connected with a synchronizing wheel I (6) through a synchronous belt (7), and the gear I (4) and the synchronizing wheel I (6) are connected onto the same motor transmission shaft. According to the utility model, the motor (1) is started to drive the gear I (4) and the synchronizing wheel I (6) to rotate at the same direction, the gear I (4) drives the gear II (5) and the inner rotating member (9) to reversely rotate, and the synchronizing wheel I (6) drives the synchronizing wheel II (8) and the outer rotating member (10) to rotate at the same direction. By the mechanism disclosed by the utility model, the motor can drive the inner and outer members to reversely rotate.

Description

Inside and outside two the mutual counter-rotational mechanisms of member of a kind of single motor driving

Technical field

The utility model relates to a kind of mechanical structure technology.

Background technique

At present, driving inside and outside two mutual backward rotation of member needs two motors usually, and cost is higher, installs and uses also inconvenient

Summary of the invention

The purpose of the utility model: propose a kind of mechanism that addresses the above problem.

For realizing the utility model, intend adopting following technology:

The utility model adopts motor to rotate by coupling band moving axis, axle rotates is with the gear one and the synchronizing wheel one that are automatically connected in axle to rotate in the same way, gear one drives gear two backward rotation that are installed in interior revolving member upper end, interior revolving member and gear two are together along backward rotation, synchronizing wheel one drives synchronizing wheel two rotating in same directions that are installed in outer revolving member upper end, outer revolving member and synchronizing wheel two make interior revolving member and the mutual backward rotation of outer revolving member together along rotating in same direction.

The utility model characteristics compared with the prior art:

Owing to utilized gear transmission and synchronizing wheel transmission, driving inside and outside two members only needs a motor, has realized simultaneously inside and outside two mutual backward rotation of member.

Description of drawings

Fig. 1 is structural representation of the present utility model.

1: motor; 2: coupling; 3: axle; 4: gear one; 5: gear two; 6: synchronizing wheel one; 7: Timing Belt; 8: synchronizing wheel two; 9: interior revolving member; 10: outer revolving member; 11: axle sleeve; 12: nut.

Embodiment

As shown in the figure: the utility model mainly comprises motor 1, gear 1, gear 25, synchronizing wheel 1, synchronizing wheel 28, Timing Belt 7, interior revolving member 9, outer revolving member 10

Motor 1 and axle 3 usefulness coupling 3 link together, gear one 4 usefulness axle sleeves 11 are fixed on axle 3 shaft shoulder upsides, synchronizing wheel one 6 usefulness nuts 12 are fixed on axle 3 shaft shoulder downsides, gear 25 is fixed in interior revolving member upper end, gear 1 and gear 25 engagements, synchronizing wheel 28 is fixed in outer revolving member 10 upper ends, and synchronizing wheel 28 is connected 6 by Timing Belt 7 connections with synchronizing wheel.

When actuating motor 1 forward, motor 1 band is automatically connected in coupling 2 forwards on motor 1 axle, coupling 2 forward bands are automatically connected in axle 3 forwards of coupling 2 the other ends, axle 3 forwards drive by nut 12 and are fixed on synchronizing wheel one 6 forwards on the axle 3, axle 3 forwards drive by axle sleeve 11 and are fixed on gear one 4 forwards on the axle 3, gear one 4 forwards drive and gear one 4 parallel meshed gears 25 counter-rotatings, the interior revolving member counter-rotating that gear 25 counter-rotatings drive and gear 25 is fixed together, synchronizing wheel one 6 forwards drive synchronizing wheel 28 forwards by Timing Belt 7 transmissions, the outer revolving member forward that synchronizing wheel 28 forwards drive and synchronizing wheel 28 is affixed, thus outer revolving member 10 and interior revolving member 9 are reversed mutually.

Claims

1. inside and outside two mutual counter-rotational mechanisms of member of a single motor driving, it is characterized in that: motor (1) rotates by coupling (2) band moving axis (3), axle (3) rotates gear one (4) and synchronizing wheel one (6) rotating in same direction that band is automatically connected in axle (3), gear one (4) drives gear two (5) backward rotation that are installed in interior revolving member (9) upper end, interior revolving member (9) and gear two (5) are together along backward rotation, synchronizing wheel one (6) drives synchronizing wheel two (8) rotating in same directions that are installed in outer revolving member (10) upper end, outer revolving member (10) and synchronizing wheel two (8) make mutually backward rotation of interior revolving member (9) and outer revolving member (10) together along rotating in same direction.
