Description

(54) ПРЕДОХРАНИТЕЛЬНАЯ МУФТА(54) PROTECTION COUPLING

Изобретение относитс к машиностроению .The invention relates to mechanical engineering.

По основному авт. св. № 855274 известна предохранительна муфта, содержаща ведущую и ведомую полумуфты, соединенные упругими пружинами с отогнутыми концами, одни из которых .размешены в углублени х втулки с фиксаторами, установленной на ведущей полумуфте, причем на наружной поверхности последней выполнены параллельно оси муфты канавки, взаимодействующие с фиксаторами Cl J According to the main author. St. 855274 known safety clutch, containing the leading and driven coupling half, connected by elastic springs with bent ends, some of which are mixed in the recesses of the sleeve with retainers mounted on the leading coupling half, and on the outer surface of the latter parallel to the axis of the coupling grooves that interact with the retainers Cl j

Недостатком этой муфты «шл етс невозможность передачи равнозначного крут щего момента при реверсе.The disadvantage of this clutch is the impossibility of transmitting an equivalent torque at the reverse.

Цель изобретени - расщирение эксплуатационных возможностей путем передачи знакопеременного момента.The purpose of the invention is to expand the operational capabilities by transferring the alternating moment.

Поставленна цель достигаетс тем, что на наружной поверхности ведущей полумуфты выполнены радиальные углублени цилиндрической формы под концы прутков.The goal is achieved by the fact that on the outer surface of the leading coupling half there are radial recesses of a cylindrical shape under the ends of the rods.

На фиг. 1 изображена муфта, общий вид ; на фиг. 2 - разрез А-А на фиг. 1.FIG. 1 shows the coupling, general view; in fig. 2 shows section A-A in FIG. one.

Муфта содержит ведущую 1 и ведомую 2 полумуфты, соединенные между собой посредством упругих элементов 3, выполненных в виде прутков с отогнутыми во взаимно перпевдикул рных плоскост х концами 4 и 5, один из которых 4 взаимодействует с ведомой полумуфтой 2, а другой 5 со смонтированной на ведущей по10 лумуфте втулкой 6, и установленных в образованных на наружной поверхности ведущей полумуфты продольных пазах 7, причем подвижна в осевом направлеиии ,j втулка 6 сопр жена посредством установлшных винтов 8 с выполненными на наружной поверхности канавками 9, которые могут быть выпсшнены продольными или по винтовой линии.The clutch contains a master 1 and a slave 2 coupling halves, interconnected by means of elastic elements 3, made in the form of rods with ends bent 4 and 5, one of which 4 interacts with the driven half coupling 2, and the other 5 with mounted on a sleeve 6 leading to 10 luminescent, and longitudinal slots 7 installed in the leading half coupling formed in the outer surface of the drive half coupling, and axially movable in the axial direction, j the sleeve 6 matched by means of the installed screws 8 with the outer surface grooves 9, which can be extended longitudinally or along a helix.

Claims

On the outer surface of the driving half coupling 1 under the bent ends 5 of the elastic elements 3 there are radial recesses 10 of cylindrical shape. The clutch works as follows. When the driving half coupling 1 rotates, the elastic elements 3, made in the form of rods with the condoms 4 and 5 bent in mutually perpendicular planes, transmit the rotation of the driven coupling half

2. Upon reaching the limiting torque, the bent ends of the elastic elements 3 begin to slip relative to the driven half coupling and thus prevent the driven part of the mechanism from being damaged. By moving the axially movable axle 6 and thereby changing the amount of free ends of the elastic elements 3, the magnitude of the torques can be correspondingly changed. When the leading semi-clutch 1 rotates in the opposite direction, the bent ends 5 of the elastic elements 3, due to the presence of the recesses 10, bend (in the opposite direction) and the torque transmitted by the clutch becomes close to that of the moment mom direction. Claims of the invention Safety clutch according to ed. St. No. 855274, characterized in that, in order to expand the operational capabilities by transferring alternating moment, radial recesses of a cylindrical shape under the ends of the rods are made on the outer surface of the driving coupling half.
