摘要： Provided are a bearing device and a main spindle device for a machine tool capable of achieving both high load capacity and high speed rotation. The bearing device has a plurality of angular contact ball bearings (41, 42, 43, 44) arranged in a back-to-back combination in an axial direction, and receives a load from one side thereof in the axial direction. Ball diameters (Da41, Da42) of the angular contact ball bearings on a load side (41, 42) are larger than ball diameters (Da43, Da44) of the angular contact ball bearings on an anti-load side (43, 44).

摘要： A front bearing (40) of the main spindle device (M) is configured such that two rows of angular ball bearings (41, 51, 42, 52) with contact angles in the same direction are arranged back to back. The angular ball bearings (41, 51, 42, 52) all have equal inner diameters, the angular ball bearings (41, 51, 42, 52) having contact angles in the same direction have equal outer diameters to each other, and the angular ball bearings (41, 51, 42, 52) having contact angles in different directions have different outer diameters from one another. In addition, with respect to at least the angular ball bearings (42, 52) having the larger outer diameters, the angular ball bearing (42) positioned on the axially outer side is set to have a larger ball diameter and contact angle than the angular ball bearing (52) positioned on the axially inner side.

摘要： A preassembled hub assembly is presented having components including the inboard and outboard bearings (30, 40), spacer (24), and lubricant seal (14) preassembled inside the hub at the manufacturing facility. In addition, the manufacturing facility also affixes a pre-positioned spindle nut assembly (50) to the hub assembly, the assembly being held in place by a retaining ring (16). The preassembled hub assembly (with the pre-positioned spindle nut assembly affixed to the hub) has no separate or loose parts, facilitating shipment and installation of the hub assembly. Installation only requires placement of the novel hub assembly on the spindle and the tightening of the factory installed, pre-positioned retaining nut (70).
摘要翻译：提出了一种预组装的轮毂组件，其具有包括内部和外侧轴承（30,40），间隔件（24）和预先组装在制造设备内的轮毂内的润滑剂密封件（14）的部件。此外，制造设备还将预定位的心轴螺母组件（50）固定到轮毂组件，该组件通过保持环（16）保持就位。预组装的轮毂组件（预定位的心轴螺母组件固定到轮毂）没有单独的或松散的部件，便于轮毂组件的装运和安装。安装只需要将新颖的轮毂组件放置在主轴上并拧紧工厂安装的预定位的固定螺母（70）。

摘要： The bearing support (64) includes a pilot ring (68) encircling an axis of rotation (24). The pilot ring is operable to be substantially-fixed in operation. The bearing support also includes a damper ring (66) operable to receive an outer race of a bearing assembly. The damper ring also encircles the axis of rotation. The bearing support also includes a fuse pin (70,70a) extending through aligned apertures in the pilot ring and the damper ring to prevent relative radial movement between the pilot ring and the damper ring up to a predetermined amount of loading. The fuse pin is operable to fracture in response to loading beyond the predetermined amount The bearing support also includes a retainer (78a) extending through one of the pilot ring and the damper ring and fixed to the other of the pilot ring and the damper ring. The retainer is operable to limit relative axial movement between the pilot ring and the damper ring. The retainer limits relative axial movement when the fuse pin fractures in response to loading beyond the predetermined amount. The fuse pin is engaged with at least one of the first and second apertures through a heat shrink fit.
