Abstract
The invention discloses a kind of electric circulation ball steering gear with double cone roller bearing, include a housing, the top of described housing is provided with a steering screw and a steering nut, the bottom of described housing is provided with a rocker arm shaft, the both ends of described steering screw are respectively equipped with a taper roll bearing, and described taper roll bearing is fixedly connected with described housing.Due to the two-way limitation steering screw of taper roll bearing energy, the lateral displacement of steering screw is effectively prevent, effectively increases the fitness of steering screw and steering nut, effectively increases the reliability of electric circulation ball steering gear.
Description
Technical field
The present invention relates to a kind of auto steerer, more precisely, being a kind of electric circulation ball steering gear with double cone roller bearing.
Background technology
Ball-and-nut steering gear is a kind of common motor turning equipment, is relatively rotated to realize by the steel ball set between steering screw and steering nut, so as to drive the sector gear on steering arm to be rotated, is turned to so as to realize.For electric circulation ball steering gear, use is electric boosted, turns to more light.The steering screw of existing steering gear is typically fixed using common ball bearing, and lateral displacement easily occurs for steering screw, influences the cooperation of steering screw and steering nut.
The content of the invention
The present invention mainly solves the technical problem present in prior art, so as to provide a kind of electric circulation ball steering gear with double cone roller bearing.
The above-mentioned technical problem of the present invention is mainly what is be addressed by following technical proposals：
A kind of electric circulation ball steering gear with double cone roller bearing, it is characterized in that, the described electric circulation ball steering gear with double cone roller bearing includes a housing, the top of described housing is provided with a steering screw and a steering nut, the bottom of described housing is provided with a rocker arm shaft, the both ends of described steering screw are respectively equipped with a taper roll bearing, and described taper roll bearing is fixedly connected with described housing.
As preferred embodiments of the present invention, described housing is aluminium alloy castings.
The electric circulation ball steering gear with double cone roller bearing of the present invention has advantages below：In use, due to the two-way limitation steering screw of taper roll bearing energy, the lateral displacement of steering screw is effectively prevent, effectively increases the fitness of steering screw and steering nut, effectively increases the reliability of electric circulation ball steering gear.The electric circulation ball diverter structure with double cone roller bearing is simple, and positive effect, cost is cheap, practical.

Embodiment
The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, apparent clearly defined so as to be made to protection scope of the present invention.
As shown in Figures 1 to 5, the electric circulation ball steering gear 1 with double cone roller bearing includes a housing 2, the top of the housing 2 is provided with a steering screw 4 and a steering nut 3, the bottom of the housing 2 is provided with a rocker arm shaft 5, the both ends of the steering screw 4 are respectively equipped with a taper roll bearing 6, and the taper roll bearing 6 is fixedly connected with the housing 2.
The housing 2 is aluminium alloy castings.
During use, as depicted in figs. 1 and 2, due to the two-way limitation steering screw 4 of the energy of taper roll bearing 6, it effectively prevent the lateral displacement of steering screw 4, the fitness of steering screw 4 and steering nut 3 is effectively increased, effectively increases the reliability of electric circulation ball steering gear.
The electric circulation ball diverter structure with double cone roller bearing is simple, and positive effect, cost is cheap, practical.
This is not limited to, any change or replacement expected without creative work, should be all included within the scope of the present invention.Therefore, protection scope of the present invention should be determined by the scope of protection defined in the claims.
