Abstract
The utility model discloses a kind of rotation mounting mechanism of internal expansion type electric beveling machine for pipes, comprise support, crossed roller bearing and mounting disc, wherein crossed roller bearing comprises upper bearing bracket, step, bearing roller and bearing inner race, upper bearing bracket, step coordinates formation cross-section to be foursquare toroidal cavity with bearing inner race, bearing roller is located in toroidal cavity, described bearing roller is cylindrical, the axis of rolling of adjacent shaft bearing roller is mutually vertical, disk retainer is provided with between adjacent shaft bearing roller, described step, bearing inner race is fixedly connected with support respectively, upper bearing bracket is fixedly connected with mounting disc.Solve that slewing gear load in traditional internal expansion type electric beveling machine for pipes is little, the problem of mutability.
Description
Technical field
The utility model relates to a kind of electric beveling machine for pipes, refers to a kind of rotation mounting mechanism of internal expansion type electric beveling machine for pipes especially.
Background technique
Complete machine is lightweight owing to having for internal expansion type electric beveling machine for pipes, cold cut is cut does not affect pipe fitting body material, be suitable for the advantages such as caliber is large is widely used.But the slewing gear in traditional internal expansion type electric beveling machine for pipes carry usually can have that lotus ability to bear is little, the change of different direction ability to bear greatly, rotation error shortcoming greatly.
model utility
The purpose of this utility model is: for the deficiencies in the prior art, and the utility model provides the rotation mounting mechanism of a kind of internal expansion type electric beveling machine for pipes that a kind of load is born greatly, validity is high.
For achieving the above object, the utility model adopts following scheme: a kind of rotation mounting mechanism of internal expansion type electric beveling machine for pipes, it is characterized in that: comprise support, crossed roller bearing and mounting disc, wherein crossed roller bearing comprises upper bearing bracket, step, bearing roller and bearing inner race, upper bearing bracket, step coordinates formation cross-section to be foursquare toroidal cavity with bearing inner race, bearing roller is located in toroidal cavity, described bearing roller is cylindrical, the axis of rolling of adjacent shaft bearing roller is mutually vertical, disk retainer is provided with between adjacent shaft bearing roller, described step, bearing inner race is fixedly connected with support respectively, upper bearing bracket is fixedly connected with mounting disc.
By adopting such scheme, consequently: intersect bearing compared to plain bearing, have and radial and axially bear that load carrying capacity is strong, running accuracy is high, simple operation and other advantages.Improve the precision of machine on the whole.
As further setting of the present utility model, described mounting disc is ring gear, and mounting disc upper surface is provided with location and installation hole.
By adopting such scheme, consequently: transmission device and erecting device are integrated, further simplify the structure of described rotation mounting mechanism, alleviating weight of equipment.
As further setting of the present utility model, described mounting disc inner side surface is provided with gear baffle, and described gear baffle is fixedly connected with support, and gear baffle is provided with arc-shaped window.
By adopting such scheme, consequently: guarantee can not there is interference between mounting disc internal tooth and crossed roller bearing, enhance reliability; Can prevent foreign matter from twisting in gear simultaneously, improve the Security of operation.
