(54) ЦЕПЬ-РЕЙКА(54) CHAIN-REIKA

II

Изобретение относитс к узлам и детал м машин, а именно к цепи-рейке, и может найти применение в качестве составной части приводных мехашзмов в различных област х машиностроени .The invention relates to units and parts of machines, namely to a rail-rail, and can be used as an integral part of driving mechanisms in various areas of mechanical engineering.

Известна цепь-рейка, содержаща последовательно расположенные вдоль оси втулки с профилированным пазом, двухсторогаше упоры , вьшолненные в виде трубчатых элементов посто нного сечени , оси, попарно соедин ющие упоры и головки втулок с возможностью их относительного поворота, и кулачки, расположенные в профилированных пазах втулок дл относительного перемещени соседних упоров в положение их контактного взаимодействи 1.A known rail-chain, containing successively located along the axis of the sleeve with a shaped groove, two-sided stops, made in the form of tubular elements of a constant section, axes connecting the stops and the heads of the sleeves in pairs with the possibility of their relative rotation, and cams located in the shaped sleeves of the sleeves for relative movement of adjacent stops to the position of their contact interaction 1.

Однако эта цепь-рейка имеет сложную конструкцию и обладает недостаточной гибкостью при работе в режиме цепи вследствие наличи двух разновидностей звеньев - втулок и упоров и дополнительных св зей между ними.However, this chain rail has a complex structure and lacks flexibility when operating in chain mode due to the presence of two types of links - bushings and stops and additional links between them.

Цель изобретени - увеличение гибкости цепи-рейки при работе в режиме цепи.The purpose of the invention is to increase the flexibility of the rail chain when operating in chain mode.

Указанна цель достигаетс тем, что упоры выполнены в виде заплечиков втулок, а кулачки установлены на ос х с возможностью их совместного поворота.This goal is achieved by the fact that the stops are made in the form of shoulder sleeves, and the cams are mounted on the axles with the possibility of their joint rotation.

На фиг. 1 изображена цепь-рейка при работе в режиме цепи; на фиг. 2 - сечение А-А на фиг. 1; на фиг. 3 - цепь-рейка при работе в режиме рейки; на фиг. 4 - сечение Б-Б на фиг. 3.FIG. 1 shows a chain rail when operating in chain mode; in fig. 2 is a section A-A in FIG. one; in fig. 3 - chain-rail when operating in rack mode; in fig. 4 is a section BB in FIG. 3

Цепь-рейка состоит из последовательно расположенных вдоль оси втулок 1, на одном конце которых имеетс профилированный паз 2, на другом - цилиндрическое отверстие дл оси 3 поворотного кулачка 4. При зтом ось кулачка совмещена с осью вращени втулок 1, проход щей через профилированный паз и цилиндрическое отверстие двух взаимодействующих звеньев. Втулки I снабжены стопором 5 дл фиксации кулачка 4.Chain-rail consists of successively along the axis of the sleeves 1, at one end of which there is a profiled groove 2, on the other - a cylindrical hole for the axis 3 of the rotary cam 4. At this, the cam axis is aligned with the axis of rotation of the sleeves 1 passing through the profiled groove and cylindrical hole of two interacting links. The sleeves I are equipped with a stopper 5 for fixing the cam 4.

Цепь-рейка работает следующим образом.Chain rake works as follows.

Claims

When the cam 4 is rotated in the profiled groove 2, the sleeves 1 are moved along the axis relative to each other until the end surfaces come into contact with the shoulders. an obstacle to the rotation of the sleeves around the axis 3 of the cam 4, which is fixed by the stopper 5, which ensures reliable tightening of the chain links to each other. Thus the chain is transformed into a rigid element - rail. When the cam 4 is reversed in the profiled groove 2, it overcomes the force of the stopper 5 and pushes the bushings apart, allowing them to rotate around the axis of the cam 3 .4, converting the rail into a chain. Such an implementation of the chain-rail makes it possible to increase its flexibility when operating in chain mode, while maintaining high stiffness characteristics and longitudinal stability when operating in the rack mode. Claim chain rail containing successively along the axis of the sleeve with profiled FIG. 1

Fig.2. 64 by a single groove, double-sided stops made in the form of tubular elements of constant cross section, axes connecting the stops and the heads of the sleeves in pairs with the possibility of their relative rotation, and cams located in the profiled grooves of the sleeves for the relative movement of adjacent stops to the position of their contact interaction, In contrast, in order to increase its flexibility when operating in chain mode, the stops are made in the form of shoulder sleeves, and the cams are mounted on the axles with the possibility of their joint rotation.
