摘要:
A power transmission belt having a load carrying band with a length, and a plurality of blocks attached to the load carrying band at preselected, spaced intervals along the length of the load carrying band. The plurality of blocks have a thickness (t), measured in a direction along the length of the load carrying band, and a width (W), measured in a direction transversely to the length of the load carrying band. Each of the plurality of blocks is made from synthetic resin material and has no shape-determining insert therein. The synthetic resin material is made from a synthetic resin having a bending modulus of 15 to 20 GPa. The ratio of t/W is from 0.11 to 0.20.
摘要:
A power transmission belt having a body with a length, a first side, a second side, and laterally spaced side surfaces. The body has cog crests and cog troughs in at least a first layer on the first side of the body and alternating the length of the body. The body further has at least one cushion rubber layer and at least one load carrying cord embedded in the at least one cushion rubber layer and extending lengthwise of the body between the cog crests and the second side of the body. The at least first layer has a first joint that is in a cog crest and does not extend into a cog trough. At least one cushion rubber layer is made from a first material, with the first material from the at least one cushion rubber layer not penetrating the first joint. The invention is also directed to a method of forming a belt of this type.

Zn-Ni-alloy electroplating of steel sheets is carried out using a plating bath containing 10-40 g/l zinc, 15-160 g/l nickel, 0.1-5 g/l cobalt and 0.2-10 g/l titanium and 0.1-5 g/l aluminum or 0.1-5 g/l magnesium existing in the form of salts, the pH of which is 1.5-2.5. The obtained plated product exhibits improved excellent corrosion resistance and corrosion peeling resistance. The product can be subjected to heating to 60.degree.-200.degree. C., preferably in hot water, steam, or atomized water mist. This treatment further increases corrosion resistance.

To realize a unit sales system of an electromotive power assisted bicycle that provides a broad range of flexibility in conformity with requirements of a user, a server computer 1-1 for distributing an electromotive power assisted bicycle according to the present invention comprises a control section 1-2 for providing a general control and management of the computer, a hard disk 1-3 for storing a set of a variety of information for providing the electromotive power assisted bicycle, and a modem 1-4 enabling the connection to a variety of different terminals via a communication network. The hard disk 1-3 stores bicycle information, electromotive power assisting information, user information, physical strength/health information, a variety of different control programs to be downloaded, information about a supplier to which an order is issued, and information about an assembly station and so on. The server computer 1-1, in response to an order from the user via the communication network 1-11, creates design information for assembling an electromotive power assisting kit 1-21 with an ordinary bicycle unit having a traveling function basically provided by a pedal effort, and sends it to the suppliers and the assembler so that a tailored electromotive power assisted bicycle 1-23 can be delivered to a user.
摘要:
A power transmission belt having an endless body with a length, an inside, and an outside. The body has cogs on at least one of the inside and outside of the body and spaced along the length of the body so as to define alternating cog crests and cog troughs. The cog crests each have oppositely facing side surfaces with an apex between the oppositely facing side surfaces. There is a reinforcing fabric on the at least one of the inside and outside of the body. The reinforcing fabric has first and second spaced end portions with a first free end at the first end portion and a second free end at the second end portion. The first and second end portions overlap so that the first and second free ends are each at a side surface on a cog crest.
