SU779683A1 - Doubled reversive overrunning coupling - Google Patents

Description

The invention relates to mechanical engineering and can be used for the automatic connection and separation of the shafts (U) and reverse of the drive shaft / ia. There is a double reverse obgche on the clutch, containing two coaxial clips, inside of which there is an asterisk, IMAGE of two rows of oppositely located work sites, and jamming rollers, which are between the asterisk and li clips. However, the clutch is complex and not reliable enough Work The purpose of the invention is to increase the reliability of the coupling. This goal is achieved due to the fact that the clutch is provided with axles, the rollers are made with central holes under the axis, each of which is installed with a pair of rollers with a gap on one axis. , FIG. 1 shows a general sectional view; FIG. 2 is a section A-A in FIG. 1 1; FIG. 3 - installation of the roller on the axis. The clutch contains a coaxially mounted scraper sh 1 and 2 mounted loosely on the hubs of the sprocket. 3, which is the leading element of mu (}) you. There are flat platforms 4 and 5 on the zveedochka, which form wedge grooves with clips, in which two rows of rollers 6 and 7, arranged in pairs with a gap on the floating axes 8, are located in the holes of the rollers. Work sites 4 and 5 on the asterisk are rotated in opposite directions for each row of rollers. The rollers are kept from axial movement by the discs 9, which are fixed at the ends of the sprocket. The clutch works as follows. When the sprocket 3 rotates clockwise, the rollers of the pitch 7 are wedged / between the working platforms 5 of the sprocket 3 and the yoke 2. A torque is transmitted from the asterisk to the yoke 2. At the same time, the rollers of pitch 6 are located between the yoke 1 and the flat working platforms 4 asterisks not

f Mile joints between them due to the fact that they are installed with a clearance on the axles. The yoke 1 has the ability to idle in either direction relative to the sprocket 3.

When the direction of rotation changes, the sprocket 3 similarly wedges the rollers of row 6 between the working platforms 4 asterisks and the yoke 1 and the torque is transmitted from the asterisk to the yoke 1. The rollers of a number 7 wedge and the yoke 2 receives the possibility of free rotation. any side relative to the asterisk 3. Formula FROM
