Abstract
The utility model relates to a roller active-active high-speed transmission mechanism. A roller assembly comprises a synchronous belt wheel II (5) which is installed at the output shaft of a roller driving motor and left and right rollers (1), the power ends of which are meshed by helical gear pairs (4). An uncoupled cylinder is arranged between two rollers. Closed cylinders are respectively arranged at one side of left and the right cylinders. A roller assembly reciprocating driving mechanism comprises a reciprocating motor (7) and an eccentric cam mechanism (6) which is installed at the output shaft of the reciprocating motor (7). The eccentric cam mechanism (6) is meshed with the roller assembly and drives the roller assembly for straight reciprocating motion. The roller active-active high-speed transmission mechanism realizes the active-active roller rotation, dynamic opening and closing during the high speed rotation of the roller and the forward-backward reciprocating motion of the roller and has vibration isolation, noise cancelling and stable movement.
Description
Affiliated field
The utility model weaving belongs to the weaving electronic instrument technology field, specifically the improvement of tester middle roller driving mechanism such as yarn evenness.
Background technology
At home and abroad in the textile industry yarn Laboratory Instruments, roller transmission mechanism adopts single drive form initiatively more, and by the synchronous rotation of two rollers of frictional force realization, and the rotating speed of roller generally is no more than 400m/min.This roller list drive form initiatively is easy to generate slippage owing to frictional force between roller is big or small non-constant between two rollers, causes roller stall, and yarn speed is not steady, thereby the test result of yarn is exerted an influence; But roller list drive form initiatively is easy to realize roller and throws off function.
In the instrument of some higher-end, although roller transmission mechanism has adopted the drive form of two actives, the roller trip gear has adopted the flexible axle drive form, and the process and assemble difficulty is bigger.
Summary of the invention
The utility model purpose is the two initiatively high speed drive of a kind of roller of design, to overcome the defective of existing transmission mechanism.
Specifically, the two initiatively high speed drive of roller, comprise roller assembly and roller assembly reciprocating drive mechanism, the roller assembly comprise the timing belt pulley II (5) that is installed on the roller drive motors output shaft and about two rollers (1), about two roller power ends by helical gear pair (4) engagement; Disengaging cylinder between two rollers, two cylinder one sides about closed cylinder lays respectively at; Roller assembly reciprocating drive mechanism comprises reciprocating motor (7) and is installed in eccentric cam mechanism (6) on the reciprocating motor output shaft that the u of eccentric cam mechanism (6) is by driving the straight reciprocating motion of roller assembly with the engagement of roller assembly.
About two rollers (1) output be fixed with timing belt pulley I (2).
All adopt the key joint of symmetry in the utility model between each gear, belt wheel and the axle.
Timing belt pulley II (5) adopts 1: 1 gearratio by a pair of helical gear pair of driven by servomotor; Timing belt pulley I (2) gearratio also is 1: 1 simultaneously.
The utility model advantage is:
1) adopt two high-precision helical gear engagements to realize the initiatively two of roller rotation.
2) adopt fork and dynamic folding when the band type of belt drive can realize that roller rotates at a high speed synchronously.
3) adopt cam mechanism to realize the front-rear reciprocation movement of roller.
4) adopt high-speed electric expreess locomotive to realize the high speed rotation of roller, the highest p-wire speed of roller is not less than 800m/min.
5) take measures such as vibration damping, noise reduction to realize vibration damping and vibration isolation, noise reduction noise reduction, guarantee the stationarity that each moves.
Description of drawings
Fig. 1 is roller rotation and roller open-and-close mechanism.
Fig. 2 is a roller travel mechanism.
The specific embodiment
This mechanism realizes that mainly roller rotates at a high speed, roller moves forward and backward and the dynamic folding of roller.
Adopt 1: 1 gearratio,, by two-way band transmission synchronously in 1: 1, drive left and right sides roller respectively again by a pair of high accuracy helical gear of driven by servomotor.Two rollers are active, no relative slippage between contact-making surface.For reducing rotary centrifugal force, guaranteeing stability of rotation, all adopt the key joint of symmetry between each gear, belt wheel and the axle, each rotating shaft is all selected the import high-precision bearing for use simultaneously, from domestic specialized factory preferred band, belt wheel synchronously, comprehensive, multi-angle reduces vibration source, reduces rotational noise.
Eccentric cam mechanism is adopted in the straight reciprocating motion of roller, utilizes DC speed-reducing, slows down by the one-level nonetallic gear, drives the eccentric mechanism front-rear reciprocation movement.
Closed and the disengagement employing double-acting cylinder realization of roller.The cylinder stroke was 2/3 of a full stroke when roller was closed, guaranteed closed reliable; Roller utilizes cylinder buffering when throwing off, guarantee the steady of motion.
