Wheel etc., gear can make single gear, it is possible to so that the gear train being made up of multiple gears, according to
Different use occasions and needs, select corresponding gear, and seamless steel pipe cold-rolling mill roll device uses
Duplicate gear be spur gear wheel.
Seamless steel pipe is common metallurgical metal goods, and cold rolling is the main of seamless steel pipe cold deformation processing
Mode, two roller cold pilgered pipe machines are widely used seamless steel pipe cold rolling production equipment, by rolling
Mechanism, main drive gear, feeding slew gear, Shou Liao mechanism, hydraulic mechanism, lubricating structure, in
Between the unit such as bindiny mechanism, plug slew gear, electric control system composition；Wherein rolling mechanism by
Support (containing slideway, tooth bar, slide plate, lathe bed), work housing (containing skate apparatus), roll etc.
Device forms, for seamless steel pipe is carried out cold deformation processing.
The support lathe bed of rolling mechanism is arranged in concrete foundation, and slideway is arranged on bottom lathe bed, tooth
Bar is arranged on lathe bed both sides, and it is 90 degree that slide plate is separately mounted to the both sides of lathe bed；Work housing is installed
On support slideway, fitted with support slideway by skate apparatus, frame underside shirt rim and support slide plate
Laminating；Roll device is divided into topping roll, bottom roll two to overlap relatively independent constructional device, wherein on roll
Roller is by elements such as roll shaft, bearing block, gear, rolling bearing, locating ring, adjustment packing ring, positioning keys
Composition, bottom roll by roll shaft, bearing block, gear train (duplicate gear), rolling bearing, locating ring,
Adjust the element such as packing ring, positioning key composition；Upper and lower roll composition kit is arranged on work housing
In；During rolling, main drive gear transmits and exports power, and work housing is at main drive gear driven axle
Under connecting rod drives, doing reciprocating horizontal motion, now bottom roll is as drive roll, by roll shaft two end tooth
Wheels (duplicate gear) outboard gears (long handle gear) engages, by level with support driving rack
Convert reciprocating motion becomes the rotary motion of roll, and by roll shaft two ends gear train (duplicate gear)
Internal gear engages with topping roll gear, is exported by rotary power, drives topping roll to do synchronous rotary fortune
Dynamic, it is achieved the rolling deformation of seamless steel tube blank is processed, therefore, improve the assembling essence of roller gear
Degree, in the service life to prolongation roll device, the rolling quality improving seamless steel pipe plays a key effect.
Due to structure and the operating characteristic of roll device, determine roll device assembly precision requirement high；
The gear that current two roller cold pilgered pipe machine roll devices are used, is straight spur gear, its
The middle difference according to driving structure, drive roll has plenty of bottom roll (russian Х П Т series rolling mill),
Has plenty of topping roll (domestic LG series rolling mill)；Driven roll uses two pinions, drive roll
Device uses two pinion groups (duplicate gear)；Gear and gear train are separately mounted to roller
The two ends of axle, wherein gear train (duplicate gear) serves both functions, on the one hand by outside profile of tooth
With engaging of support tooth bar, the horizontal movement of work housing is converted to the rotary motion of drive roll, separately
On the one hand engaging by inner side profile of tooth and driven roll gear, drives driven roll to do synchronous rotary and moves,
Therefore the assembly precision of duplex-gear wheels, directly influences the kinematic accuracy of a whole set of roll device, and with
The rolling accuracy of seamless steel pipe, quality are closely related.
As a example by Х П Т-55 cold pilger mill, drive roll is bottom roll, and driven roll is topping roll；Its
The straight spur gear that the duplicate gear that bottom roll device uses is different by the two pieces number of teeth, modulus is identical,
Wherein outside (long handle gear) modulus m=15, number of teeth z=25, inboard gear modulus m=15, tooth
Number z=26, is formed by temperature differential method assembled orientation, uses interference fit, and flat key positions；Constitute duplex
The two pieces gear of gear, the number of teeth differs 1, therefore reference diameter all differs with the outside diameter of gear, and
Starting point tooth-formation of gear involute two sides (flank profil) must guarantee to overlap, the most just when assembling
Can ensure that duplicate gear and support tooth bar, the Synchronous Transmission precision symbol of topping roll gear of bottom roll both sides
The technology requirement of conjunction equipment；The generally assembly precision of duplicate gear checks starting point tooth-formation of gear exactly
The registration of involute two sides (flank profil), error amount D is 0～0.06mm, therefore assembles at roll
In, the assembling of duplicate gear is a difficult point, is also a crucial operation control point.
The assembling mode of the duplicate gear that bottom roll device uses is temperature differential method assembled orientation and 90 at present
Degree angle square is measured and is adjusted, it may be assumed that utilize firing equipment that the gear of z=26 is heated to certain temperature,
After bore expanded by heating, direct it on the axle journal of the long handle gear being assemblied in z=25；Utilize
90 ° of angle squares, overlap by measuring the tooth top plane vertical line of two pieces gear, and rotary fine adjustment in time, real
The precision assembling of existing duplicate gear, its operation technique is:
1. assembling prepares:
Cleaning gear: cleaning, wiping bore and profile of tooth, repaiies burr, reconditioning keyway etc.；Inspection:
The data such as difference prototype gear endoporus, the axle journal of long handle gear, width of keyway, profile angle；

D) assembling gear: be transported to verify above platform by the gear after heating, after wiping endoporus, will
The endoporus assembled orientation of z=26 gear is on the long handle gear axle journal of z=25；
E) registration is adjusted: use an angle of 90 degrees chi, by measuring the tooth top plane vertical line weight of two pieces gear
Close, and rotary fine adjustment in time, until meeting technology requirement；
F) counterweight is placed: place counterweight (preventing from cooling down backgear to shift up) at z=26 gear top；
3. gear checking: after duplicate gear cooling, use an angle of 90 degrees chi, by measuring the tooth of two pieces gear
Top plane vertical line registration, checks assembly precision, and the needs not meeting precision are done over again, and (top is torn open double
Connection gear, ressembles)；

As≤4 months)；
2. technical ability skill requirement is high: owing to constituting two kinds of outside diameter of gear differences of duplex-gear wheels, respectively
It is 392mm, 378mm, therefore uses the miter square face of an angle of 90 degrees chi, measure two pieces different-diameter
The tooth top plane vertical line registration of gear is the most difficult, needs spatially extended, the technical ability to operating personnel
Skill requirement is higher, and below usual senior work, personnel typically cannot operate；
3. the activity duration is short: owing to using temperature differential method assembled orientation, duplicate gear contact surface after heating
