A grease composition for a constant velocity joint comprising the following components (A) to (E): (A) a base oil containing 10 to 95% by mass of an ester synthetic oil produced from an aliphatic alcohol and an aromatic carboxylic acid and 90 to 5% by mass of a synthetic hydrocarbon oil; (B) a thickener; (C) molybdenum disulfide; (D) molybdenum dialkyldithiocarbamate e; and (E) zinc dithiophosphate.
摘要:
The present invention provides a grease composition for use in constant velocity joints, having improved wear resistance and endurance characteristics.The grease is made by incorporating in a urea grease (A) a molybdenum dialkyldithiocarbamate, (B) a molybdenum dithiophosphate, (C) 2-(4-morpholinyldithio)benzothiazole and (D) a calcium sulphonate. The blended amount of (A)+(B) is made not more than 10% by weight, and that of (C) and (D) not more than 3% by weight respectively. Also, a grease for use in constant velocity joints is made by further adding (E) zinc dithiophosphate to the aforementioned components (A)+(B)+(C)+(D) in a blended amount of not more than 3% by weight.
摘要:
A constant velocity joint structure including an inner joint member, a retaining ring, and a shaft which are configured to prevent the shaft from being withdrawn from the inner joint member when a pulling force is applied to one side of the shaft is disclosed. A retaining ring groove is disposed at an opposite side of the shaft. In a preferred embodiment, the retaining groove has at least two points which contact an inner surface of the retaining ring when the pulling force is applied to prevent the retaining ring from contracting in a radial direction, thereby preventing the shaft from being withdrawn from the inner joint member.
摘要:
The present invention provides a boot for a constant velocity universal joint in which a portion of the boot does not interfere with an ear section of a boot band even when the joint is at a high operating angle. The present invention is the boot for a constant velocity universal joint housing a torque transmitting component between an outer joint component and an inner joint component and in which a shaft connected to the inner joint component extends outside of the joint. The boot is disposed between an outer circumference of the outer joint component and an outer circumference of an intermediate section of the shaft. The boot includes a cylindrical large diameter section 1a that is fixed onto an outer circumferential surface of an outer joint component 2 by a boot band 3, a cylindrical small diameter section that is fixed onto an outer circumferential surface of the shaft, a bellows section 1d that connects the large diameter section and the small diameter section, and a shoulder section 1c that is provided between the large diameter section and the bellows section and covers an opening end side outer circumferential surface of the outer joint component. The shoulder section 1c is extended by a predetermined length from the boot band 3 to an opening end side of the outer joint component.

Portal server connects with a plurality of content supply servers and is also connectable with a client terminal via a communication network. Each of the plurality of content supply servers has music content. The portal server is accessed by the client terminal, and the portal server transmits, to the client terminal, a list of music content suppliable by the content supply servers, in response to a request from the client terminal. Desired music content can be selected in the client terminal on the basis of the list transmitted by the portal server, and selection information specifying the selected music content can be transmitted from the client terminal to the communication network. Then, in response to the selection information, the selected music content can be supplied from the content supply server having the selected music content.
摘要:
There is provided a communication terminal apparatus that enables quick response in screen display and quick retrieval of desired melodies in a musical tone data distributing service and reduces a communication fee. A java incoming call melody program including core display data is received from a server apparatus through the Internet and is stored in a RAM. When the stored program is executed, a display screen is formed based on the core display data according to the program and is displayed on a display. A cellular phone receives the distributing service by receiving desired musical tone data from the server apparatus via the Internet using the display screen.
