A housing element for applications in the manufacturing industry having a casing and a cover both made of metallic material, wherein the casing is provided with a groove and a flat mounting surface and the cover is provided with an end portion having a frustoconical side wall, an oblique annular bottom wall, and a securing system consisting in inserting the end portion of the cover inside the groove of the casing, wherein an interference (i) between a radially outer end of the end portion of the cover and a radially inner end of the flat mounting surface of the casing assumes values of between 0.2 mm and 0.5 mm and an angle (δ) defined between the frustoconical side wall of the end portion of the cover and the flat mounting surface of the casing assumes values of between 45° and 80°. The interference and the angle facilitate the insertion of the end portion of the cover inside the groove of the casing.

The invention provides a radially expanding fastener/alignment plug assembly for use with a torque power tool, the assembly including: a sleeve member (10), insertable into a hole of an object, having radial expansion elements with inner surface portions which are tapered towards a first end; an expanding member (20), insertable in the sleeve member, having an outer surface portion which is tapered towards a first end, cooperating with the inner tapered surface portions of the radial expansion elements of the sleeve member; and a displacement member (30) formed between a second end of the sleeve member and a second end of the expanding member. Advantageously, the assembly is self-reacting allowing an actuation torque to be applied to and reacted upon to create high levels of pulling and expansion force without the need for an external reaction point.

According to the invention, there is provided a magnetic wear liner (10) for protecting an underlying metallic surface (12) of a materials handling device from wear or damage during use. The magnetic wear liner includes a substantially rigid base (16) and one or more wear lining tiles (18) disposed on one side of the rigid base. The magnetic wear liner further includes one or more magnet devices (26) engageable with the rigid base such that a selective portion of the wear liner (10) is magnetically attracted to the underlying metallic surface.

A multi-mount assembly disposed on a fastening structure that has a U-type rail is provided. The multi-mount assembly includes a main body having a quadrilateral rail, a positioning hole, and a passage. The quadrilateral rail is disposed along a periphery of the main body. The positioning hole is in a side of the main body facing away from the fastening structure. The passage is spatially communicated with a first edge and a second edge of the main body, in which the first edge is opposite the second edge. The main body is configured to enter an opening of the U-type rail of the fastening structure such that three sides of the quadrilateral rail are coupled to the U-type rail. The positioning hole is configured to enable a protruding element to pass therethrough.

A connection system includes a shaft, a hollow shaft, a press ring, a first ring fitted onto the hollow shaft, a second ring, a bearing, and a housing part. The hollow shaft is rotatably mounted via the bearing received in the housing part and has an inner conical region. The first ring has a first outer conical region and a second outer conical region. The first outer conical region is positioned against the inner conical region of the hollow shaft and/or at least a partial region of the first outer conical region is arranged radially between the shaft and the hollow shaft. The second ring encloses and/or surrounds the first ring. The press ring touches both a partial region of the radially outer surface of the hollow shaft and at least one partial region of the radially outer surface of the second ring and/or is mounted onto these partial regions.

A support structure including: a body (12) having a press-fitting hole (36); and a collar (34) that is press-fit into the press-fitting hole. The support structure is characterized in that: the collar includes a press-fitting part (34a) at an area that is press-fit into the press-fitting hole, a flange part (34c) provided to one end side of the press-fitting part, and a distally-tapered tapered part (34b) provided to the other end side of the press-fitting part. The press-fitting hole includes a press-fitted hole at an area into which the press-fitting part is press-fit, an intrusion hole at an area into which the tapered part intrudes, and a circumferential groove part provided between the press-fitted hole and the intrusion hole. When the axial-direction length of the press-fitting part is a, the axial-direction length of the press-fitted hole is b, and the axial-direction length of the circumferential groove part is c, b<a<b+c.

An induction heating system can be adapted for shrink fitting a plurality of different assemblies. A plurality of tooling units associated to respective ones of the assemblies, each one having an appropriately configured induction coil and holder, can be provided. A computer can be used to control the delivery of electrical power to the induction coil in accordance with a heating recipe, and can be provided with an input device for inputting an assembly identifier allowing the computer to operate the control based on the right heating recipe.

A structural member is elongated in a longitudinal direction, and includes a first member made of a steel plate and a second member made of a steel plate, the first member and the second member being joined. In the structural member, a closed cross-sectional shape is formed by the first member and the second member in a cross section perpendicular to the longitudinal direction. The first member has a tensile strength of equal to or greater than 980 MPa, and includes a first hemming process part subjected to hemming bending at both end parts in a width direction orthogonal to the longitudinal direction. The second member has a tensile strength of equal to or greater than 980 MPa, and includes a second bonded part held in the first hemming process part at both end parts in the width direction and bonded to the first hemming process part by an adhesive.

A fastener and a method of mounting the same in place includes a fitting portion, an engaging portion and a filler portion. The fastener passes through a sliding hole of an object, and then the fitting portion presses against the object, allowing a material of the object to enter or flow into the filler portion, so as to fit the fastener and the object firmly together. The engaging portion is engaged with or removed from another object. Therefore, the fastener and the method can couple together and separate at least two objects repeatedly and rapidly.
