Description

(5) SPRING ELASTIC COUPLING

one

The invention relates to mechanical engineering and can be used to connect the shafts of machines and mechanisms under increased loads.

Known serrated elastic coupling, containing a driven half coupling, grasping its leading coupling half, made with a toothed crown on the inner surface, spread between the gears that are mounted on axles mounted on the driven half coupling and intermeshing to the coupling half of the coupling half, and elastic elements With 1., 5

However, the coupling has insufficient load and damping abilities, since the elastic elements are fixed at the end of the driven half coupling and have a cantilever loading, and the gears with a toothed rim of the driving coupling half have one gearing area.

The purpose of the invention is to increase the load and damping capacity of the coupling. The goal is achieved by having a gear-type elastic coupling containing a driven half coupling covering the drive plate, which is made with a toothed ring on the inner surface, placed between the coupling half gears mounted on axles attached to the driven the coupling half, and the entrance and engagement with the crown of the leading coupling half, and elastic elements, one of the coupling halves is provided with an additional gear crown with external teeth that engage with the pole pH m, while the latter are made up of two parts in the form of segments, between which are installed elastic elements.

Claims (3)

. With this, an additional gearing can be performed both on the driven half coupling and on the leading coupling half, and the component parts of the gear 9 can be made both with the same height and with different heights. FIG. 1 shows a flexible camshaft coupling, general view; in fig. 2 section A-A in FIG. one; in fig. 3uprugi gear coupling, another option to install an additional gear rim; in fig. k is a section BB in FIG. 3 The coupling consists of a leading half coupling 1, having a gear rim 2 with internal teeth, a driven half}) you 3, on which gears k are mounted on axles 5j evenly spaced around the circumference. The gears k are made up of two parts in the form of segments, between which resilient elements 6 are arranged in the form of rubber plates. These elastic elements can be attached to the segments of gears, for example, using vulcanization or in another way. Segments of each gear can have the same height (Fig. 2) or a different height (Fig. K). With different heights of gear segments t they have segments with a lower height, facing the axis of the coupling. The clutch is equipped with an additional gear crown 7 with external teeth m. This crown 7 prays to be performed on the leading coupling half 1 (Fig. 1). It can be the same installed on the driven coupling half 3 (Fig. 3). The gears k are engaged with the gear rims 2 and 7 (Fig. 2 and 4). The operation of the clutch is carried out as follows. When the leading half coupling 1 (Fig. 1) rotates, the toothed rims 2 and 7 act on the segments of the gears L, turning them in mutually opposite directions. In this case, the gear segments with their opposing flat edges exert pressure on the elastic elements 6, and through the axles 5 they drive away the driven coupling half. 3 in rotation. If the additional gear rim 7 is located on the driven half coupling 3 (Fig. 3 and), then when the leading floor rotates at the coupling 1, it with its toothed rim 2 acts on the component parts with gears that carry the half coupling half 3 through the axles 5 and the gear crown 7 in rotation. 4 As the torque transmitted by the clutch increases, gears k turn around their axes, creating pressure on the elastic elements 6 followed by their deformation, while the jagged segments swing a little over the toothed rim 7 of the driven coupling half 3, perceiving part of the transmitted clutch load. The proposed design has a high load carrying capacity, along with good damping properties, since the load is distributed HV two gearing zones, and the attachment of elastic elements reduces the impact loads.
