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

Известна упруга торсионна муфта, содержаща ведущую и ведомую полумуфты , соединенные торсионом, состо щим из плоских Н-образной формы пластин, установленных в диаметральных пазах, выполненных , в полумуфтах 1.A resilient torsion clutch is known, containing a driving and driven half coupling, connected by a torsion consisting of flat H-shaped plates mounted in diametrical grooves made in the half couplings 1.

Недостаток этой муфты заключаетс в недолговечности из-за больших напр жений см ти в местах креплени торсиона.The disadvantage of this coupling lies in its fragility due to the high stress of smithing at the points of attachment of the torsion.

Известна торсионна муфта, содержаща ведущую и ведомую полу муфты, соединенные торсионом, состо щим из пакета плоских пластин, концы которых установлены в диаметральных пазах на внутренних торцах полумуфт, при этом пакеты плоских пластин размещены взаимно перпендикул рно 2.A known torsional clutch containing a leading and driven half of the coupling is connected by a torsion consisting of a pack of flat plates, the ends of which are installed in diametral grooves on the inner ends of the coupling halves, while the packs of flat plates are placed mutually perpendicular 2.

Однако эта муфта имеет небольшую надежность , обусловленную сложными напр жени ми изгиба в торсионе.However, this coupling has little reliability due to complex bending stresses in the torsion.

Цель изобретени - повышение над жности .The purpose of the invention is to increase the reliability.

Цель достигаетс тем, что упруга торсионна муфта, содержаща ведущую иThe goal is achieved by the fact that the elastic torsion clutch containing the drive and

ведомую полумуфты, соединенные торсионом из пакета пластин, закрепленных на полумуфтах, пластины каждого пакета выполнены дугообразной формы, на полумуфтах выполнены радиальные пазы, а концы пакетов закреплены в этих пазах.the driven coupling halves, connected by a torsion of a plate package, mounted on the coupling halves, the plates of each package are arched, radial grooves are made on the coupling halves, and the ends of the packages are fixed in these slots.

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

Муфта содержит ведущую полумуфту 1, ведомую полумуфту 2, кажда из которыхThe clutch contains the leading half coupling 1, the driven half coupling 2, each of which

10 выполнена за одно целое с крестовиной, с радиальными пазами 3, в которых установлены пакеты 4-7 пластин дугообразной формы, закрепленные при помощи клиновидны с элементов 8 и гаек 9, навернутых на резьбовые фланцы 10.10 is made in one piece with the crosspiece, with radial grooves 3, in which packages of 4-7 plates of arcuate shape are mounted, fixed with the aid of wedge-shaped elements 8 and nuts 9, screwed onto threaded flanges 10.

Claims

The coupling works as follows. The torque is transmitted from the drive half of the clutch to the driven through the plate packs 4-7. As the load increases above the limit, the leading coupling half is rotated relative to the driven one by twisting the torsion within its elastic deformation. When the load decreases, the half coupling returns to its original position. By reducing the torsional stiffness and reducing the stress concentrations in the plates, the reliability of the coupling is increased. Claims of the invention An elastic torsion clutch comprising a drive and a driven coupling half connected by a torsion of plate packages mounted on the coupling half, characterized in that. In order to increase reliability, the plates of each package are made arcuate, radial grooves are made on the half-couplings, and the ends of the packages are fixed in these grooves. № Sources of information taken into account in the examination 1.
