Problems solved by technology

The reason for this may be that the bottom of the groove of the wheel according to the first four publications discussed is substantially parallel to the axis of the wheel, and the side walls of the groove of the wheel are substantially perpendicular to the axis of the wheel, thereby differing from that according to Compared to the situation presented in the sprocket of US 3 415 135A, the chain links have a certain degree of freedom of movement, however, in the case of large support loads, before the chain links reach their replacement due to wear. Exclude chain damage

Embodiment Construction

[0022] figure 1 and 2 Shows two halves of a grooved sprocket that are detachably or non-detachably connected to each other. Either of the two halves form 5 grooves 3 whose bottom 4 has straight portions 4a and 4b enclosing an angle β of about 160° in order to avoid contact between the weld seam of the sprocket and the bottom 4 .

[0023] The respectively consecutive slots 3 of the slot arches arranged offset from one another in the circumferential direction of the wheel are separated from one another by teeth 5 having tooth roots for transmitting forces to the chain links of the chain cables Surface 6. The bottom 4 of the groove 3 and the root face 6 of the tooth 5 extend parallel to the axis 8 of the groove sprocket, while the side walls 9 of the groove 3 are perpendicular, except for a small transition zone 7 provided to avoid slot stress Oriented on said axis 8 . In any case, the radius of the transition zone 7 should be less than half the diameter d of the links of th...

Abstract

Disclosed is a pocket-type sprocket comprising two groups of pockets (3) for chain members (10) of a chain section which pass the sprocket at an angle a relative to the sprocket axis (8), said groups of pockets (3) being disposed next to and offset from each other. In order for the angle a to be determined exclusively by the diameter d of the material used and the internal width bi of the chain members (10) at a given number of teeth of the sprocket, it is ensured that the contact between the chain members (10) and the pockets (3) is limited to the area of the faces of the teeth.

Description

technical field [0001] The invention relates to a grooved sprocket for chain drives of hoisting gear and lifting equipment, said grooved sprocket comprising two sets of grooves for chain links which are at an angle α with respect to the wheel axis With a wheel, the two sets of grooves are arranged close to each other and offset from each other, in the sprocket each groove is defined by a bottom, a side wall, and two transverse webs forming teeth, and wherein the opposite groove sides The distance A occupied by the wall is greater than the dimension a of the link measured in the direction of the wheel axis. Background technique [0002] A grooved sprocket of the above-mentioned type is already known from DE 44 06 623 C1. In known sprockets, the links are supported with legs arranged close to the axis on the part of the bottom and with legs arranged away from the axis on the area forming the transverse web of the tooth of the wheel, said area facing away from the Said legs o...
