TL;DR: The utility model discloses a gear engagement formula swing drives device belongs to slewing bearing technical field as discussed by the authors, and it has pair casing to advance the location tang of line location installation to circle processing in it.
Abstract: The utility model discloses a gear engagement formula swing drives device belongs to slewing bearing technical field. The utility model discloses a gear engagement formula swing drives device, including rotary supporting device, this rotary supporting device installs in the casing, and its outer lane is passed through the pinion and is linked to each other with the drive unit drive, and it has pair casing to advance the location tang of line location installation to circle processing in it, the faying face of casing and inner circle corresponds respectively and is equipped with first semi -circular dimple groove and the semi -circular dimple groove of second, and eccentric packing ring is installed with the semi -circular dimple inslot of second in first semi -circular dimple groove to fixcasing and inner circle through holding screw II. Adopt the utility model discloses an above not enough that current swing drives device exists can effectively be solved to the swing drives device, and it is little to have an installation space of occuping, and self compact structure is light, and sealing performance advantage such as good has prolonged slewing bearing's life greatly.

TL;DR: In this paper, a VR universal treadmill with a rotating steel frame and a rotating flange is presented. But the VR universal MT is not suitable for the use with children, as it is unsuitable for children due to poor exercise experience.
Abstract: The utility model discloses a VR universal treadmill, which relates to the technical field of fitness equipment and comprises a slewing bearing fixing plate, a slewing bearing, a rotating flange, a first driving device, a speed reducer, a controller, a rotating steel frame and a treadmill assembly, the outer ring of the slewing bearing is fixedly arranged; the output end of the first driving device is connected with the speed reducer; the speed reducer is connected with the inner ring of the slewing bearing; the device is used for driving a slewing bearing inner ring to rotate. The inner ringof the slewing bearing is connected with the rotating flange; the rotary steel frame is fixedly connected with the rotary flange; the controller and the treadmill assembly are both fixedly arranged onthe rotary steel frame. The treadmill assembly is electrically connected with the controller; and the controller is electrically connected with the first driving device, so that the defect of poor exercise experience of a user due to relative displacement of the existing treadmill in the running process of the user is overcome, the user can perform acceleration, deceleration and steering actionson the VR universal treadmill, and the exercise experience of the user is improved.

TL;DR: In this paper, a thrust deep-groove ball slewing bearing is described, where the shape of the steel balls is the same as that of the isolation blocks, and the steel ball rolling paths are arranged on the upper and lower clamping rings.
Abstract: A thrust deep-groove ball slewing bearing belongs to slewing bearings, and comprises an upper clamping ring, a lower clamping ring, steel balls and isolation blocks, wherein the steel balls and the isolation blocks are arranged between the upper clamping ring and the lower clamping ring and are arranged at intervals; the shape of the steel balls is the same as that of the isolation blocks; steel ball rolling paths are arranged on the upper clamping ring and the lower clamping ring; and oil troughs are formed at the bottom ends of the steel ball rolling paths; and the contact angle between an upper clamping ring steel ball track and a lower clamping ring steel ball track is 90 degrees. The difference between the internal diameter dimension and the external diameter dimension of the slewing bearing is reduced, and the contact angle is 90 degrees, that is, the intersection angle between the force transferring direction of the rolling body and the radial plane of the slewing bearing is 90 degrees. The thrust deep-groove ball slewing bearing has the advantages that the structure space is small, the rotational moment is small, the bearing axial force is large, and the processing technology of the upper clamping ring and the lower clamping ring is simple; and when assembly is conducted, the assembly of the upper and the lower clamping rings and the steel balls is convenient.
