摘要:
A hand-held circular saw is designed so that a fan exhaust air from a fan wheel is introduced into a sawdust duct along the shortest path in a duct arranged inside a gearing housing, in order to reinforce a conveying of saw dust in the sawdust duct. The fan air is fed parallel to the movement direction of the sawdust, effects a vacuum in the sawdust duct and prevents stoppage of the duct.
摘要:
In an elevator element for driving or reversing an elevator suspension device in an elevator system, that interacts with an elevator suspension device, the arithmetic mean of the roughness value of the contact surface measured in the circumferential direction of the elevator element, and the mean roughness value of the contact surface measured in the axial direction of the elevator element, are different. The arithmetic mean roughness value of the contact surface measured in the circumferential direction of the elevator element is less than 1 micrometer.
摘要:
An elevator system with a car or platform to transport passengers and/or goods as well as with a counterweight, which are arranged as traversable or movable along a travel path, and which are coupled and/or with a drive by a suspension element interrelating their motion. The suspension element is guided and/or driven by a traction sheave and/or a drive shaft and/or a deflecting pulley. The suspension element is sheathed and/or belt-type, with a first layer made of a first plasticizable and/or elastomeric material, containing a first exterior surface, and with at least one tension member—rope-type, tissue-type, or comprising a multitude of partial elements—that is embedded in the first layer of the suspension element. A manufacturing procedure for one of the suspension elements is provided.
