Description
Изобретение относитс к области машиностроени .The invention relates to the field of engineering.
Известно шпоночное соединение, содержаш ,ее втулку, вал и шпонку, закренленную на валу, примен емое дл подвижных соедннений 1:.A keyed connection is known, comprising its sleeve, a shaft and a key locked on a shaft, used for moving connections 1 :.
Данное соединение не может примен тьс в точных механизмах из-за зазоров, по вл юшихс вследствие износа шпонки.This connection cannot be used in precise mechanisms due to gaps resulting from key wear.
Известно также иноночное соединение втулки с валом, содержащее шпонку в виде усеченной пирамиды, установленную в пазу вала и закрепленную во втулке с помощью полого винта 2.It is also known inonochnoe connection of the sleeve with the shaft, containing a key in the form of a truncated pyramid, installed in the groove of the shaft and fixed in the sleeve with a hollow screw 2.
Данное устройство вл- етс наиболее близким к изобретению по технической сущности и достигаемому эффекту.This device is closest to the invention in its technical essence and the effect achieved.
Однако данное соединение при использовании его в качестве подвижного не может примен тьс в точных механизмах вследствие зазоров из-за износа шнонки.However, this compound, when used as a rolling one, cannot be used in precise mechanisms due to gaps due to wear on the pins.
Дл этого в предлагаемом шпоночном соединении с целью расширени эксплуатационных возможностей шпонка подпружинена относительно винта в направлении, нерпендикул рном к оси вала.For this, in the proposed key connection, in order to expand the operational capabilities, the key is spring-loaded with respect to the screw in a direction that is perpendicular to the axis of the shaft.
На фиг. 1 изображено шпоночное соединение с осевым перемещением вала или втулки; на фиг. 2 -сечение А-А на фиг. 1; на фиг. 3 - шпоночное соединение с поворотом вала или втулки; на фиг.-4 - сечение Б-Б на фиг. 3.FIG. 1 shows a keyed connection with axial movement of the shaft or sleeve; in fig. 2 is a section A-A in FIG. one; in fig. 3 - keyed connection with rotation of the shaft or sleeve; FIG. 4 shows a section BB in FIG. 3
Соединение состоит из шпонки 1 в виде нравильной усеченной пирамиды с цилиндрическим хвостовиком 2, установленной в осевом З.или круговом 4 пазах вала 5.The connection consists of a key 1 in the form of a moral truncated pyramid with a cylindrical shank 2 installed in the axial Z.or circular or 4 grooves of the shaft 5.
Полый винт 6 выполнен глухим с конической резьбой и закреплен во втулке 7. Шпонка 1 установлена цилиндрическим хвостовиком 2 с минимальным зазором в цилиндрической полости винта 6 и подпружинена относительно него пружиной 8 через прокладку 9. Отверстие 10 в шпонке 1 служит дл смазки соединени .The hollow screw 6 is made blind with a tapered thread and is fixed in the sleeve 7. The key 1 is mounted with a cylindrical shank 2 with a minimum clearance in the cylindrical cavity of the screw 6 and is spring-loaded with a spring 8 through the gasket 9. The hole 10 in the key 1 serves to lubricate the joint.
Соединение работает следующим образом .The connection works as follows.
Шпонка фиксирует вал в одном направлении и позвол ет перемещение в другом направлении. Износ шпонки и паза крмпенсируетс пружиной 8 и ирокладкой 9. Коническа резьба винта предохран ет соединение от загр знени и преп тствует вытеканию смазки. Смазка может закладыватьс в полость между дном винта и шнонки или подаватьс через масленку, устанавливаемую в винт 6. После износа двух граней шпонка может поворачиватьс на 90°. хA key locks the shaft in one direction and allows movement in the other direction. The wear of the key and the groove is reinforced by the spring 8 and the laying 9. The conical thread of the screw protects the connection from contamination and prevents the lubricant from leaking out. The lubricant can be inserted into the cavity between the bottom of the screw and the pins or fed through an oilcan installed in screw 6. After the two faces are worn, the key can be rotated 90 °. x
