Abstract
The utility model discloses an enclosed type electric roller carrier which is composed of an active roller carrier 1 and a passive roller carrier 2. The enclosed type electric roller carrier is used by matched with an automatic welding frame to undertake the automatic welding works of the inner and the external circular seams and the longitudinal seam of a round barrel. The active roller of the active roller carrier is an enclosed type electric roller gathering ' drive, deceleration and load bearing ' as integration, and the active roller of the active roller carrier is that an improved double reduction gear of few teeth difference is arranged in the active roller. The transmission principle of the utility model is that the spinning motion of a planet wheel is limited, the planet wheel is made to do movement of ' translational movement ' following an eccentric shaft, and a ring gear is driven by the planet wheel by which the movement of ' translational movement ' is done to directly output power.
Description
The utility model relates to a kind of with welding the matching used closed type electric turning rolls of frame automatically, bears the automatic weld job of the inside and outside circumferential weld of garden shape cylindrical shell, longitudinal joint.
Prior art is self-regulated (adjustable) center turning rolls, is by the active roller frame, and passive turning rolls constitutes.Particularly the deceleration transmission system layout of active roller frame is outside roller body, be by:
Adjust motor---shaft coupling---worm reducer---shaft coupling---
Its weak point is: transmission link is many, and mechanical efficiency is low, and physical dimension is big, and mechanical efficiency average near 25% is unfavorable for saving energy and reduce the cost.
The purpose of this utility model is that a kind of active roller will be provided is by the few tooth difference secondary planet speed reduction gearing of modified, is arranged in the roller body, and collection " drive, slow down, carrying " be the closed type electric turning rolls of the closed type electric roller formation of one.Can dwindle physical dimension effectively, improve mechanical efficiency, reach energy-saving and cost-reducing purpose.
The utility model is made of active roller frame, passive turning rolls, and its active roller is the closed type electric roller.
The purpose of this utility model is achieved in that with the few tooth difference secondary planet speed reduction gearing of modified, the deceleration transmission system of the existing technology of displacement also is arranged in it in the active roller body, has constituted collection " drive, slow down, carrying " and has been the closed type electric roller of one.Its transmission principle is the spinning motion of restriction planetary gear, and makes it do " translation " motion with eccentric shaft, and the planetary gear of doing " translation " motion drives the direct outputting power of inner gear ring.
The utility model dwindles 1/3 owing to adopted the collection " driving, deceleration, carrying " of the few tooth difference secondary planet deceleration device formation of modified to be the closed type electric roller of one thereby make volume show technology, and quality alleviates 1/2, and mechanical efficiency improves nearly four times.
Specific embodiment of the utility model is provided by the following drawings:
Accompanying drawing 1 is the structure diagram of self-regulated center closed type electric turning rolls:
Active roller frame (1), passive roller (2) has constituted the closed type electric turning rolls.On the active roller frame (1), two groups of rollers are installed, and each group roller a closed type electric roller is all arranged is active roller (3), another is passive roller (4).Two groups four passive rollers (4) are also arranged on the passive turning rolls (2).The function of active roller (3) is " drive, slow down, carry "; The function of passive roller (4) is " carrying, servo-actuated ".Two same respectively two active rollers (3) direct connections of direct current generator (1) that model is identical, driving rolls rotates synchronously, unites use with thyristor speed control device (not providing among the figure), makes active roller carry out the stepless speed regulation of 8～48m/h.
Accompanying drawing 2 is transmission sketches of closed type electric roller:
The output shaft of direct current generator (1 '), a double-eccentric shaft (2 ') oppositely eccentric with the high speed level connects firmly, input power; On the rotor journal of eccentric shaft (2 '), stagger mutually 180 ° two duplicate gear hobbing planetary gears (5) are installed, there are two to be symmetrically distributed in and to go up isodiametric pin-and-hole garden, center week and be inserted in spacing bearing pin (4 ') on the fixing limiting plate (3 ') on it, equating of the same planetary gear of garden, center diameter (5) of bearing pin (4 '), under the drive of eccentric shaft (2 '), planetary gear (5) is the garden heart with the axis of bearing pin (4 '), with the eccentric throw is that radius is done " translation " motion, the planetary gear of doing " translation " motion drives the ring gear (6) that is meshed with it and rotates in fixed axis, directly outputting power is given slow speed turbine stage eccentric shaft (7), two colleague's dental star wheels (5) that version is identical are installed on the rotor journal, and the different planetary gear (8) of physical dimension, the pin-and-hole of planetary gear (8), be inserted in two the spacing bearing pins (10) on the fixing limiting plate (11), planetary gear (8) is done " translation " motion with eccentric shaft, the planetary gear (8) of doing " translation " motion directly drives ring gear (9), the same roller body of ring gear (9) (12) is affixed, outputting power rotates synchronously.
Claims (2)
1, rolling frame, particularly closed type electric turning rolls are made of active roller frame, passive turning rolls,
It is characterized in that deceleration device is arranged in the active roller body, constituted collection " driving, deceleration, carrying " and be the closed type electric roller of one.
2, turning rolls according to claim 1 is characterized in that deceleration device is a modified fewer differential teeth planetary reduction gearing mechanism.
