Abstract
The invention discloses a kind of equal strength quill shaft and end cap assembly of ball mill, it leads rib by quill shaft, axle journal, end cap and multi-head spiral to form, the outer surface of quill shaft is the face of cylinder, the face of cylinder of its protrusions is axle journal, quill shaft inner surface is frusto-conical surface, and quill shaft inwall has multi-head spiral and leads rib; End cap surfaces externally and internally is frusto-conical surface, outer surface cone angle is less than inner surface cone angle, the strength structure that quill shaft and the transition of end cap Rouno Cormer Pregrinding Wheel link into an integrated entity, make quill shaft and end cap each cross section equal strength, the face of cylinder of axle journal projection improves the strength and stiffness of necked part, its deflection under the effect of hydrostatic bearing hydraulic oil is reduced greatly, and the oil film thickness impact of its deflection on hydrostatic bearing is very micro-, and reduces the deadweight of quill shaft and end cap to a certain extent.Solve the contradiction between its strength and stiffness and deadweight.
Description
Technical field
The present invention relates to a kind of quill shaft and end cap assembly, particularly a kind of equal strength quill shaft of ball mill and end cap.
Background technology
The specification of ball mill constantly increases, and quill shaft and end cap are the critical components of ball mill, has higher requirement to its design, the quill shaft of existing ball mill and the contradiction of end cap strength and stiffness and deadweight more outstanding.
Summary of the invention
The object of this invention is to provide a kind of equal strength quill shaft and end cap assembly of ball mill.
The present invention leads rib by quill shaft, axle journal, end cap and multi-head spiral to form, and the outer surface of quill shaft is the face of cylinder, and the face of cylinder of its protrusions is axle journal, and quill shaft inner surface is frusto-conical surface, and quill shaft inwall has multi-head spiral and leads rib; End cap surfaces externally and internally is frusto-conical surface, and outer surface cone angle is less than inner surface cone angle, the strength structure that quill shaft and the transition of end cap Rouno Cormer Pregrinding Wheel link into an integrated entity.
Beneficial effect of the present invention: there is the end cap integrative-structure that the quill shaft of the outer surface face of cylinder and inner surface frusto-conical surface and surfaces externally and internally are frusto-conical surface, make quill shaft and end cap each cross section equal strength, the face of cylinder of axle journal projection improves the strength and stiffness of necked part, its deflection under the effect of hydrostatic bearing hydraulic oil is reduced greatly, the oil film thickness impact of its deflection on hydrostatic bearing is very micro-, and reduces the deadweight of quill shaft and end cap to a certain extent.Solve the contradiction between its strength and stiffness and deadweight.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Refer to shown in Fig. 1, the quill shaft of the present invention and end cap 30 lead rib 304 by quill shaft 301, axle journal 302, end cap 303 and multi-head spiral to form, the outer surface of quill shaft 301 is the face of cylinder, the face of cylinder of its protrusions is axle journal 302, quill shaft 301 inner surface is frusto-conical surface, and quill shaft 301 inwall has multi-head spiral and leads rib 304; End cap 303 surfaces externally and internally is frusto-conical surface, and outer surface cone angle is less than inner surface cone angle, the strength structure that quill shaft 301 and the transition of end cap 303 Rouno Cormer Pregrinding Wheel link into an integrated entity.
