Изобретение относитс к подъемно-транспортному машиностроению, а именно к роликоопорам рольгангов.FIELD OF THE INVENTION The invention relates to a lifting and transport machinery, in particular to roller carriages.

По основному авт. св. N 680950 известна роликоопора рольганга, содержаща поворотный корпус с установленными на нем свободно вращающимис на оси сферическими роликами , расположенными в двух взаимно перпендикул рных плоскост х. Сферические ролики установлены внутри корпуса , при этом две части сферической поверхности каждого ролика расположены на диаметрально противоположных сторонах корпуса.According to the main author. St. N 680950 is known for a roller-carrier of a roller table, comprising a rotary body with spherical rollers mounted on it freely rotating on an axis and arranged in two mutually perpendicular planes. Spherical rollers are installed inside the housing, with two parts of the spherical surface of each roller located on diametrically opposite sides of the housing.

Длина каждой из двух дуг сферической поверхности ролика в сечении вдоль его оси равна четверти длины полной окружности сферы.The length of each of the two arcs of the spherical surface of the roller in a section along its axis is equal to a quarter of the length of the full circle of the sphere.

В известной роликоопоре упрощена ее конструкци и снижен вес f11.In the known roller support, its structure is simplified and the weight f11 is reduced.

Однако вследствие того, что сферические ролики выполнены неприводными , отвод грузов с рольганга дол2However, due to the fact that the spherical rollers are made non-driven, the removal of goods from the roller table 2

Применение сталкиватепей со своими отдельными приводами значительно усложн ет конструкцию рольганга. Кроме того, требуетс дополнительна производственна пло10 щадь дл установки их, а это не всегда возможно, особенно в стесненных услови х.Women are made either manually or with the use of additional pushing devices. Manual pushing of loads is a laborious and inefficient operation that requires large labor costs. The use of collisions with their individual drives greatly complicates the design of the roller table. In addition, additional production space is required to install them, and this is not always possible, especially in cramped conditions.

Цель изобретени - обеспечение механизированного отвода груза с The purpose of the invention is the provision of mechanized removal of cargo with

Указанна цель достигаетс тем, что роликоопора снабжена установленным под корпусом приводным валом с закрепленными на нем шестерн ми с This goal is achieved by the fact that the roller support is provided with a drive shaft mounted under the casing with gears attached to it

Claims

20 helical teeth, and on the surface of the spherical rollers are helical teeth, interacting with the gear teeth. Fig, 1 shows a roller conveyor, a plan view; in fig. 2 shows section A-A in FIG. one; in fig. 3 section bb in fig.

2. The roller carrier has a body T, swivel on pins 2 from an asterisk 3 connected by a chain with a drive (not shown). Inside the body are spherical rollers 5 freely rotating on axes 6 fixed to the body. Spherical rollers are installed in two mutually perpendicular planes. Two parts a and b of the spherical surface of each roller are located on diametrically opposite sides of the housing 1. The length 2, each of the two arcs of the spherical surface of the roller along its axis is equal to a quarter for the full circumference of the sphere (Fig. 3). On the surface of the spherical rollers 5 there are screw teeth 7 Under the body 1 mounted in supports 8, the shaft 9 connected with the roller drive by means of an asterisk 10. On the shaft 9 there are fixed gears 11 with helical teeth. The number of gears 11 is equal to the number of rollers 5, each gear interacting with one of the rollers, forming a screw pair with it. The spherical rollers of one glare support are arranged in a checkerboard pattern relative to the rollers of the adjacent support. The rollgang works as follows. The rotation from the drive of the roller conveyor through sprockets 3 and 10 is transmitted to housing 1 with rollers 5 and shaft 9 with gears 11. In this case, rollers 5 with their helical teeth periodically engage with helical teeth of gears 11. For transporting cargo along the roller table in the longitudinal The direction (arrow K in Fig. 1) of the rollers 5 and gears 11 is communicated with the same circumferential speeds, so that the rollers 5 will not rotate around their axes when entering the gear with the gears. To discharge loads from the roller table, the rollers 5 and gear 11 provide different peripheral speeds both in magnitude and direction, with the result that the rollers receive additional rotation around their axes 6 in one direction or another and divert the cargo from the roller table. The message to the rollers and gear wheels of different speeds can be implemented in various ways: by disconnecting the sprocket 3 or asterisk 10 from the drive. In both cases, due to the interaction of the teeth of the rollers with the gear wheels, the rollers rotate in one direction or another and drop the load from the roller table. Thus, the proposed design of roller supports provides a mechanized removal of goods from the roller table on both its sides. It does not require the use of any dischargers, for the installation of which additional space is required. Live rolls can be used to work in cramped conditions. Claims for the invention of a roller carrier on the auth. St. No. 680950, characterized in that, in order to provide a mechanized removal of cargo from the roller table, the roller prop is provided with a drive shaft mounted under the body with gears with helical teeth fixed on it, and on the surface of the spherical rollers there are screw teeth . with teeth gears.
