摘要： The present invention seeks to provide a turbine blade with increased creep capability for both uncooled and cooled turbine blades while generally maintaining operating stress levels at an interface region between the turbine blade and a turbine disk. A turbine blade is disclosed having an attachment, a neck, a platform, and an airfoil. Extending radially outward from the attachment, through the neck, and terminating radially inward of the platform is a plurality of first cavities. The turbine blade in accordance with the preferred embodiment of the present invention is cast from a high density nickel base alloy with high temperature capability and improved creep capability. A plurality of first cavities are placed in the attachment and neck region to reduce excess weight of the turbine blade due to the higher density, greater creep capable alloy. Reducing the weight of the blade in this region provides increased creep capability in the turbine blade airfoil while maintaining operating stress levels.
摘要翻译：本发明寻求提供一种涡轮叶片，其具有对未冷却和冷却的涡轮机叶片具有增加的蠕变能力，同时通常维持在涡轮机叶片和涡轮盘之间的界面区域处的操作应力水平。公开了一种具有附件，颈部，平台和翼型的涡轮叶片。从附件径向向外延伸穿过颈部并且从该平台的径向向内延伸的是多个第一腔。根据本发明的优选实施例的涡轮叶片由具有高温能力和改进的蠕变能力的高密度镍基合金铸造。多个第一腔被放置在附接和颈部区域中，以便由于较高的密度，较大的可蠕变的合金而减少涡轮叶片的重量。在该区域中减小叶片的重量在涡轮叶片翼型件中提供增加的蠕变能力，同时保持操作应力水平。

摘要： An assembly for coupling a dump truck bed to a frame of a work machine includes an attachment member secured in fixed relation to the frame. The attachment member has a plurality of first fastener apertures defined therein. The assembly also includes a hydraulic cylinder having a first end and a second end. The first end of the hydraulic cylinder is pivotally coupled to the dump truck bed. The assembly further includes a bearing assembly having an inner race and an outer race, wherein (i) the outer race is disposed around the inner race such that the outer race rotates in relation to the inner race thereby defining a central axis of rotation, (ii) the outer race is fixed in relation to the second end of the hydraulic cylinder, (iii) the inner race is fixed in relation to the attachment member, and (iv) the inner race has a plurality of second fastener apertures defined therein. The assembly also includes a plurality bolts respectively positioned within the plurality of first apertures of the attachment member and the plurality of second apertures of the inner race so as to secure the inner race to the attachment member, wherein the plurality of first apertures of the attachment member and the plurality of second apertures of the inner race are each eccentrically located relative to the central axis of rotation.
