Patent number: 10180367Abstract: Proposed is a method of determining optimal operation conditions for treating holes with a rotary tool by performing a hole treatment operation on a tester under various treatment conditions which are similar to the use of the tool in the industrial production on a real manufacturing equipment. The method consists of changing the treatment conditions and determining those operation parameters at which the treated hole is most optimally satisfies the given technical requirements. A criterion for evaluation of these optimal conditions is equality of pair forces acting on the rotary tool in the X- and Y-axis directions since such a situation prevents sidewise deviation of the tool from the direction of the thrust force applied in the Z-axis direction. The above condition is provided by the specific structure of the tester used for carrying out the method.Type: GrantFiled: December 24, 2016Date of Patent: January 15, 2019Inventors: Vishal Khosla, Nick Doe, Jun Xiao, Ming Chan, Gautam Char

Patent number: 7634948Abstract: A process and device for dynamic measurement of the axial deformation of a rotating hollow shaft (10), a glass fiber segment (16) of a fiber optic sensor (18) being attached securely to a section of the inside wall of the hollow shaft (10) extending in axial alignment with the shaft. A light signal produced by a light source (24) is injected into the glass fiber segment (16), and the light signal being detected by a detector (28) after passing through the glass fiber segment (16). Axial deformation of the section of the inside wall of the hollow shaft (10) is ascertained by determining axial deformation of the glass fiber segment (16) from the change of at least one parameter of the light signal that occurs when the light signal passes through the glass fiber segment (16).Type: GrantFiled: December 17, 2007Date of Patent: December 22, 2009Assignee: Prueftechnik Dieter Busch AGInventor: Edwin Becker

Patent number: 7617610Abstract: The present invention relates to a method of measuring a clearance of a hub bearing for vehicles. A hub is fixed to a lower jig when a row of hub-side balls is disposed and an outer ring is disposed on an outer periphery of the hub and a row of inner ring-side balls and an inner ring are disposed. A press-fit jig is contacted to the inner ring and a load of less than 5 kgf is applied to an outer surface of the outer ring to prevent its vibration and movement. A gauge is installed to a portion of the outer ring. The inner ring is gradually press-fitted by the jig. An amount of press-fit of the inner ring is measured from when the gauge begins to move when press-fitting of the inner ring is completed. The amount of clearance is simply measured.Type: GrantFiled: May 29, 2007Date of Patent: November 17, 2009Assignee: Il Jin Global Co., LtdInventors: Young Su Song, Suk Yong Bae

Patent number: 7526967Abstract: A measuring device for detecting stresses of a bearing arrangement. The stresses are measured based on elastic changes in shape. The inventive measuring device includes a light source, which is directed onto a light passage, and a light sensor. The dimensions of a portion of the light that penetrates the light passage and impinges the light sensor can be modified by elastically changing the shape of the light passage.Type: GrantFiled: August 12, 2005Date of Patent: May 5, 2009Assignee: Schaeffler KGInventor: Stefan Glueck

Publication number: 20080289436Abstract: The invention relates to a measuring apparatus (200) in connection with a gear (10). The gear comprises at least one first shaft (11) and at least one second shaft (14), a gear wheel placed on the first shaft (11) and comprising a helical toothing, which gear wheel (12) cooperates with a gear wheel (13) provided with a helical toothing and located on the second shaft (14). The gear (10) comprises in its connection the measuring apparatus (200), by means of which the axial force transmitted to the shaft (11) can be measured. The measuring apparatus (200) for measuring axial force comprises a bearing (17) located in connection with the shaft (11) in the gear, which bearing receives the axial forces. The axial force is transmitted further via the bearing (17). The device arrangement comprises a rod (20) to which the axial force is transmitted from the bearing (17), the rod (20) being located between the bearing (17) receiving the axial forces and the housing (100) of the gear.Type: ApplicationFiled: July 1, 2005Publication date: November 27, 2008Applicant: Moventas OyInventor: Pekka Laakkonen

Patent number: 6967586Abstract: A bearing test method and a bearing test device are provided for bearings in which a non-contact state is maintained between a shaft element and a bearing element in a normal rotation state. In addition, a motor bearing monitoring device is provided to detect an abnormality in a motor or that a motor's life is near its end, where the motor utilizes the bearing. Furthermore, a storage device such as a hard disk drive equipped with the motor monitoring device is provided. For a bearing that can retain a shaft element and a bearing element coaxially positioned in a non-contact state when the number of revolutions exceeds a predetermined number of relative revolutions, a bearing test method is provided to determine whether the shaft element and the bearing element are in a contact rotation state.Type: GrantFiled: October 16, 2001Date of Patent: November 22, 2005Assignee: Sankyo Seiki Mfg.
