  • Publication number: 20140367132
    Abstract: To improve the durability of a bearing mechanism such as a rolling bearing that is provided between a secondary hammer and a spindle in an impact wrench configured to firmly tighten screws by applying an impact in the rotational direction of an anvil, using a primary hammer and the secondary hammer, a technique is provided in which a rolling bearing is used as the bearing mechanism, the inner circumference of the secondary hammer is press-fitted to an outer ring of the rolling bearing, and a gap is created between the outer circumference of a spindle and an inner ring of the rolling bearing. The created gap can exhibit the effect of cushioning precession rotation of the secondary hammer to reduce the radial load that is applied to the rolling bearing, and, as a result, improve the durability of the rolling bearing and extend the life of the bearing.

  • Patent number: 8864902
    Abstract: A cement clinker which can be sintered at 1,300 to 1,400° C. which is lower than the conventional sintering temperature and develops excellent strength characteristics such as mortar compression strength. The cement clinker has a total content of C3A and C4AF calculated by Bogue's formulas of 22 mass % or more, a C3S content calculated by Bogue's formula of 60 mass % or more and an iron modulus (I.M.) of 1.3 or less, preferably 1.0 to 1.3. Since the total content of C3A and C4AF is 22 mass % or more, the cement clinker can be sintered at a low temperature and the reduction of strength when a cement composition is cured can be prevented by reducing the iron modulus of the cement clinker.

The cement clinker has a total content of C3A and C4AF calculated by Bogue's formulas of 22 mass % or more, a C35 content calculated by Bogue's formula of 60 mass % or more and an iron modulus (I.M.) of 1.3 or less, preferably 1.0 to 1.3. Since the total content of C3A and C4AF is 22 mass % or more, the cement clinker can be sintered at a low temperature and the reduction of strength when a cement composition is cured can be prevented by reducing the iron modulus of the cement clinker.

  • Patent number: 8490714
    Abstract: An impact wrench is provided that can mitigate vibrations in the axial direction without reducing the rotary impact force of hammers. The hammers are composed of a primary hammer fitted to the outer circumference of a spindle and a cylindrical secondary hammer that is disposed so as to cover the primary hammer and that rotates integrally with the primary hammer. Furthermore, the secondary hammer is held by a center holding means in a state in which the rotational axis of the secondary hammer is coincident with the axis of the spindle in order to prevent run-out movement. With the use of the hammer configuration of the present invention, the mass of the primary hammer can be decreased compared to that of the secondary hammer, and therefore it is possible to mitigate vibrations in the axial direction while maintaining the rotary impact force.
