Abstract

The utility model relates to a synchronizing action mechanism for realizing the sport unit, which is used for various devices of the requiring finished synchronizing action in the realized mechanical field, and which is used in other occasions for realizing the synchronizing action. The utility model mainly comprises a flexible component, a wheel group and a connecting device. The flexible component is a sealed flexible drive chain, and the wheel group is consisting of a plurality of pulleys or chain wheels. A flexible component is wound on each wheel of the wheel group, and at least two connecting devices are arranged on the flexible component. The utility model aims to solve the existing problems that the distant synchronizing drive mechanism is limited by space, etc. Or other negative factors, and adopts the servocontrol which makes the complicated degree of the system overtop, etc. The method overcomes the insufficiency of the traditional realizing synchronizing action means, and various structural distortion combinations can be carried out; the effect is conspicuous especially for the distant action component synchronization. The utility model can be widely used in various devices for realizing the action synchronization.

Description

A kind of lazy-tongs of flexible transmission

One, technical field: the utility model relates to a kind of mechanism that realizes the moving cell synchronization motion, a kind of brand-new innovation and creation based on flexible member realization synchronization motion are provided, it is mainly used in all kinds of devices that need to finish synchronization motion in the realization mechanical field, also can be applicable to the occasion that other need realize synchronization motion.

Two, background technique: at present, the method that is used to realize synchronization motion in machinery mainly contains based on various rigidly connected are synchronized with the movement and based on various servo-controlled being synchronized with the movement.

Higher based on its reliability of rigidly connected synchronizer, being applicable between the member that needs the realization synchronization motion has enough spaces, connects the no interference phenomenon in back, and the nearer occasion of distance between parts that is synchronized with the movement.For at a distance synchronously, because the method volume heaviness, power consumption is big and the restriction of spatial arrangement or the like unfavorable factor and can't adopting.

Based on servo-controlled synchronizer, based on automatic control theory, its application flexibility increases, but the system complex degree is too high, and the cost of equipment and use, maintenance cost etc. are all very high.

Three, summary of the invention:

1, goal of the invention: the deficiency that is synchronized with the movement at above realization, the utility model provides a kind of lazy-tongs of flexible transmission, and its purpose is to solve remote rigidly connected lazy-tongs are subjected to the restriction of unfavorable factors such as space and adopt servocontrol to make the system complex degree cross the problem that high aspect exists.

2, technological scheme: the utility model comes to be realized by the following technical programs:

A kind of lazy-tongs of flexible transmission, it is characterized in that: it mainly is made up of compliant member, wheels and connection set, compliant member is the flexible transmission chain of a sealing, wheels are the wheels that a plurality of pulleys or sprocket wheel are formed, article one, compliant member be wrapped in the wheels each take turns, compliant member is provided with at least two connection sets.

The pulley of wheels or sprocket wheel are for being 4 at least.

The pulley of wheels or sprocket wheel are 6, and the layout of wheels is parallel to each other the line segment 4,5,6 of the compliant member that is provided with connection set, and one of them connection set is arranged on the line segment 6, and another connection set is arranged on line segment 4 or 5.

The pulley of wheels or sprocket wheel are 10, part symmetry about the layout of wheels makes, and the corresponding line segment of compliant member all is parallel to each other.

Compliant member is wire rope or nylon rope or chain.

3, advantage and effect: this method has overcome the be synchronized with the movement deficiency of means of traditional realization, can carry out multiple malformation combination, has very strong adaptability.Its structural principle is simple, reliable performance, and the manufacturing and the maintenance cost of equipment are low.Especially synchronous to remote moving element, effect is remarkable, can be widely used in all kinds of devices that needs are realized synchronized movement.

Four, description of drawings: accompanying drawing 1 is the winding scheme of six wheels;

Accompanying drawing 2 is the winding scheme of five wheels;

Accompanying drawing 3 is the winding scheme of four-wheel group;

Accompanying drawing 4 be six wheels twine scheme turn to modification 1;

Accompanying drawing 5 be six wheels twine scheme turn to modification 2.

Five, embodiment:

Mechanism of the present utility model is to use a kind of flexible connecting member the member of synchronization motion to be achieved is connected with each other, and reaches the purpose of synchronized movement between member by compliant member and the different canoes between wheels.The method can realize moving element easily along being synchronized with the movement of different direction, and flexibility is strong, can be applicable to various site conditions by the distortion combination, has high adaptive capacity.

Main constituent elements: compliant member 1, wheels 2, connection set 3.

Wherein compliant member 1 can be wire rope, nylon rope, chain etc.; Wheels 2 are corresponding sheave block, chain wheel set etc.; The visual concrete component form that needs to connect of connector is determined.

Here be the synchronous in the same way implementation procedure of example explanation with six wheels winding schemes.Its basic method for arranging as shown in Figure 1, wherein 1 is compliant member, 2 is wheels, 3 is the lockout member connection set.In the middle of the system that forms with this three class A of geometric unitA, driver part can be arranged in connection chain any and be convenient to realize the position that drives, as: a certain wheel is driving link, or a certain suitable activation point as driving link of compliant member, also can directly drive unit to be synchronized with the movement.After having determined driver part, can realize waiting to be synchronized with the movement the synchronization motion of unit in connection chain by two connection sets 3.

The motion of drive unit will make compliant member 1 move in a certain direction around wheels 2, thereby realize the synchronization motion of moving cell.Can be realized that be arranged on the line segment 5 as 3 one of connection sets in the accompanying drawing 1, one is arranged on the line segment 6 by changing the position of connection set 3 in Transmitted chains along being synchronized with the movement of different motion direction, the member of synchronization motion is for being synchronized with the movement; 3 one of connection sets are arranged on the line segment 4, and one is arranged on the line segment 6, and the member of synchronization motion is the reverse sync motion.

Accompanying drawing 2,3,4,5 is several schematic representation of the concrete annexation of the utility model, but the technical program is not limited to this several forms.Here need illustrate a bit, in process of production, the factor that the requirement of working environment is very important often, in actual applications, can be by the quantity of taking turns in the concrete installation conditions adjustment wheels and the relative position of each wheel, to satisfy the site space requirement.Like this, the floor space minimum is saved more production space.So, be most preferred embodiment with accompanying drawing 1,4,5.
