Abstract
A cone press fit bolster in a ring spinner roller bearing spindle comprises an elastic pipe and a bearing base and is characterized in that the press fit section of the elastic pipe is a truncated cone with the end head being large and the inner end being small, the center of the bearing base is provided with a cone-shaped hole which coincides with the press fit section of the elastic section, and the press fit section of the elastic pipe is in interference cone press fit connection with the cone-shaped hole in the bearing base. The press fit of a linear ex-circle of the elastic pipe and a linear hole in the bearing base is changed into the press fit of a cone ex-circle of the elastic pipe and the cone-shaped hole in the bearing base, the coaxial degree of a bearing hole of the bearing base and a spindle bottom R can be better guaranteed due to the guiding and centering functions of the cone-shaped hole, the bolster sinking phenomenon due to the sinking of the elastic pipe in the operating process of the spindle can be avoided, the structure is stable and reliable, and the service life is long.
Description
Technical field
The utility model relates to a kind of ring spinner parts, and particularly a kind of cone is press-fitted bolster shell.
Background technology
Bolster shell is the critical component in ring spinner roller bearing spindle, is made up of elastic tube and bearing block.In traditional bolster shell structure, the end that is press-fitted of elastic tube is cylinder, press-fit holes in respective shaft bearing is circular hole, the end that is press-fitted of elastic tube is joined and is connected to form with the press-fit holes interference vertical compression in bearing block, is press-fitted in process, and at the bottom of bearing block bearing hole and ingot, the axiality of R is joined by vertical compression easily affects, thereby affect complete spindle quality, meanwhile, in mechanical oscillation process, exist elastic tube to sink and cause bolster sinking hidden danger.
Summary of the invention
The purpose of this utility model is the above-mentioned weak point in order to overcome prior art, and provide a kind of in ensureing existing product serviceability, avoid spindle operation process Elastic pipe to sink and cause bolster sinkage, Stability Analysis of Structures is reliable, and the cone of long service life is press-fitted bolster shell.
For achieving the above object, the technical solution adopted in the utility model is: a kind of cone is press-fitted bolster shell, comprise elastic tube, bearing block, the section of being press-fitted that it is characterized in that elastic tube is large, the inner little truncated cone in termination, there is the bellmouth matching with the elastic tube section of being press-fitted at bearing block center, and the elastic tube section of being press-fitted is press-fitted and is connected with the bellmouth interference cone in bearing block.
The further technical scheme that the utility model adopts is: the truncated cone outer surface of the section of being press-fitted of elastic tube has equally distributed axial raised line.
The utility model is owing to adopting above architecture advances, straight hole in straight elastic tube cylindrical and bearing block is press-fitted and is improved to taper hole in elastic tube cone cylindrical and bearing block and is press-fitted, due to guiding, the centering effect of taper hole, can ensure better the axiality of R at the bottom of the dead eye of bearing block and ingot, can avoid spindle operation process Elastic pipe to sink and cause bolster sinkage simultaneously, Stability Analysis of Structures is reliable, long service life.
