摘要:
A brush holder (10) for a motor and having a plate-shaped base body (11) having an opening (13) for passing the motor rotor (30) therethrough, at least one brush receptacle (14) in which a carbon brush (15) is displaceably received, and an electronics can (12) projecting from the plate-shaped base body (11), closed at its side (21) adjacent to an axis (A) defined by the base body opening (13), and having an inner chamber (22) in which at least a portion of components of control electronics is received.
摘要:
An open elongate profile has side walls (12, 13; 22; 32) oriented relative to each other in a direction of a longitudinal extension (L) of the side walls, with at least one of the side walls (12; 22; 32) having at least one thickness-reduced region (14; 24; 34) along its longitudinal extent (L) and a shaped profile (15; 25; 35) provided in the at least one thickness-reduced region (14; 24; 34) of the at least one of the side walls (12; 22; 32).
摘要:
The system (31) for angular connection of mounting rails comprises a U-shaped connection member (1) that has on at least one lateral wall (2.1, 2.2, 3) openings (4.1, 4.2, 4.3) for passage therethrough of a fastener for fastening a connection member (1) to a mounting rail and a connection plate (21). The connection plate (21) has insertion projections (22.1, 22.2, 23) that can be inserted into insertion holes (5.1, 5.2, 6) provided for this purpose on the connection member (1). Using the bolt (25) the connection system (31) is fastened and at the same time the connection plate (25) is tightened with the connection member (1).
摘要:
A device for fastening tubular objects includes a C-shaped mounting rail (3) and a rail nut formed of a hollow profile having at least two constriction areas (13a, 13b and 14a, 14b) defining a through-opening (8) which is formed by two hollow cylindrical sections (9a, 9b) extending parallel to a longitudinal axis of the through-opening (8) and having respective inner thread sections (10a, 10b) for receiving a fastening element there between.
摘要:
An attachment construction (11) for anchoring means at a steel support (1) comprises a mounting element (12) and three U-shaped attaching elements (21) each arranged using mounting means (15) pivotly on a mounting element (12). The attaching elements (21) each have a receptacle (25) for a fixation means of the associated anchoring means. The receptacle (25) is configured as a slot-shaped aperture running over the entire U-shaped connecting element (21).
摘要:
Polyvinyl-alcohol-stabilized redispersible powders which have plasticizing properties are obtained by drying polyvinyl-alcohol-stabilized aqueous dispersions of polymers of one or more monomers from the group of vinyl esters of optionally branched C1-18 alkylcarboxylic acids, (meth)acrylic esters of optionally branched C1-15 alcohols, dienes, olefins, vinylaromatics and vinylhalides, in the presence of a copolymer formed from a) one or more monomers from the group of ethylenically unsaturated monocarboxylic acids, ethylenically unsaturated dicarboxylic acids and their anhydrides, each having 4 to 8 carbon atoms, and salts thereof, b) one or more ethylenically unsaturated compounds containing sulfonic, sulfuric, and/or phosphonic acid groups, and salts thereof, and c) one or more monomers from the group consisting of vinyl esters of optionally branched C1-18 alkylcarboxylic acids and (meth)acrylic esters of optionally branched C1-15 alcohols.
摘要:
A support for installations in the field of housing technology and industry includes first and second chords (12; 62 and 16; 66) each formed of two parallel elongate profiles (13, 17; 63, 67) spaced by a distance (A, B; C, E) from each other and being connected by connection profiles, with a longitudinal extent of the connection profiles (14, 18; 64) intersecting a longitudinal extent of the elongate profiles (13, 17; 63) of the chords (12, 16; 62) and being greater than the distance (A, B; C) between the elongate profiles (13, 17; 63), the support further including two longitudinally extending wave-shaped bars (21; 71) for connecting the first and second chords (12, 16; 62, 66) and having turnover regions (22; 72, 74) connected with the elongate profiles (13, 16; 63, 67) of the first and second chords, respectively.
摘要:
A quick mounting nut (2) movable, at least partially, without being rotated, axially to a threaded bolt (1), with a springing wire clip (4) being located in a nut housing (5) with a continuous coaxial opening (6), with the wire clip (4) at least partially engaging in a bolt thread (3) and having two legs (8, 8′) which spring relative to one another, with the opening (6) having an inner cone (7) which narrows radially from an axial neutral position of the wire clip (4) and with the wire clip (4) being movable axially to a limited extent and contacting at least partially inside the inner cone (7) in its locking position.
