摘要： PURPOSE:To prevent a drum and a lining both from unusual wear and tear, by installing a radiation fin in the side of a brake drum, while constituting it so as to cause the cooling air produced by the fin to flow inside the drum, in case of a brake gear for a hydraulic crane's wire hoisting winch or the like. CONSTITUTION:Each of radiation fins 21 and 22 being titled as far as the specified angles alpha and beta to a rotation direction A of a brake drum 2 is set up at both sides 2A and 2B of the brake drum 2. In this constitution, with the brake drum 2 rotated, the radiation fin 21 feeds cooling air toward the drum 2 as in an arrow direction. In this drum 2, since an air passage 23 is pierced through, the cooling air passes the air passage 23 and flows out of the side of the radiation fin 22, then diffused and discharged outside by the radiation fin 22, during which the brake drum 2 is cooled. Like this, with the brake drum cooled, wear and thermal deformation in the drum and the lining are all prevented, thus the prolongation of their service life can be brought to fruition.

摘要： PURPOSE:To prevent extroadinary wear of a drum and a lining through suppression of a rise in temperature of the central part of a frictional surface, by circumferentially forming a groove for cooling in the frictional surface of the drum. CONSTITUTION:A groove 21, having about the same width and depth over the whole periphery, is provided in the approximately central part of a frictional surface 2 of a drum 1. Braking is set such that a lining 13 is forcibly pressed against the frictional surface 2 with a movable band 8 pulled. In this case, the heat so generated is carried by an air current, flowing in the groove 21 through a undercut in a shoe, and is dissipated in the open air. As noted above, the central part, which is usually brought in a highest temperature condition, is cooled, and this brings whole temperature distribution into uniformity and prevents the occurrence of deviated wear of a drum and a lining.

2 is further formed. When the piston will move to the right the cushion plunger 23 is fitted with a cushion member 27 to reduce the flow path area thus to produce the high pressure in the chamber A and to provide the resistance against the piston 21. Consequently the cushion effect can be improved when compared with the conventional one by the resistance of the pressurized oil flowing in the gaps S
