Automatic transmission case

The level of quietness for an automatic transmission case is ensured by preventing vibration by improving the rigidity while suppressing the increase in the mass of a transmission case. In an automatic transmission case in which a valve body is attached to a case wall that covers the transmission mechanism, the rigidity of the automatic transmission case is increased by providing, in the case, an enclosing wall that projects out from the case wall and encloses the periphery of the valve body.

Method for rapidly replacing strained sieve net and vibration sieve

InactiveCN103611678ANo skill proficiency requiredEffective fasteningSievingScreeningStrakePulp and paper industry
The invention relates to the field of the material sieving technology, in particular to a method for rapidly replacing a strained sieve net and a vibration sieve. The vibration sieve comprises a sieve frame, a net frame, the sieve net and a net straining strake. The net frame is arranged in the sieve frame. The vibration sieve is characterized in that the net straining strake is arranged on the inner wall of the sieve frame, a through hole is formed in the position, corresponding to the net straining strake, of the sieve frame, and an end portion of the net straining strake is penetrated out of the through hole; when the sieve net is replaced, the sieve net is horizontally placed on the net frame, the sieve frame is placed on another sieve net and falls off, and the sieve net is attached to the outer wall of the net frame after the sieve frame bends the sieve net downwards; an end portion of the net straining strake is linked with a straining device, and the net straining strake can be tightened by operating the straining device. As the sieve frame and the net straining strake are of an integral structure, when the sieve net is replaced, the sieve net just needs to be flatly placed at the upper end of the net frame, and then the sieve frame is placed on the sieve net and falls off at a time. The sieve frame vertically falls off to bend the sieve net so that the sieve net can be attached to the outer wall of the net frame. The sieve net does not need to be manually bent and the requirement for the skill proficiency of an operator does not exist.
