Abstract
The utility model relates to provides a kind of variable-ratio milling unit head, by casing, and large belt wheel, synchronous cog belt, small pulley, motor, motor rack, cutter shaft, milling cutter forms, and casing is supporting member, supporting motor frame and cutter shaft, large belt wheel and milling cutter are installed in cutter shaft two ends, and large belt wheel and small pulley are formed V belt translation by synchronous cog belt, and common asynchronous moter is arranged on motor rack 6.By changing the number of teeth of large belt wheel and small pulley, the rotating speed of cutter shaft and milling cutter can be changed.The beneficial effects of the utility model are, according to the width in gap to be processed, can change band tooth number, thus change gearratio, reach the object changing milling cutter rotating speed.
Description
Technical field
The utility model discloses a kind of variable-ratio milling unit head, belong to a kind of cutting seam sieve tube processing unit (plant).
Background technology
Cutting seam sieve tube is drilling well sand control important tool equipment, and a screen casing will cut thousands of gaps, and domestic and international effective method uses milling cutter slot.Because gap width to be processed differs, wish according to the wide change milling cutter rotating speed of seam.At present, variable-frequency motor is generally used to drive milling cutter speed change both at home and abroad.Because the feature of cutting seam sieve tube processing is that every lot number amount is very large, stitch wide specification constant, often criticizing in process, motor speed does not change, just motor speed can be changed when just changing batch specification, in addition variable-frequency motor price is more expensive, so adopt replacing driving parts more convenient, economic, practical.
Summary of the invention
In order to solve above-mentioned existing issue, the utility model provides a kind of variable-ratio milling unit head, by casing 1, large belt wheel 2, synchronous cog belt 3, small pulley 4, motor 5, motor rack 6, cutter shaft 7, milling cutter 8 forms, it is characterized in that: described casing 1 is supporting member, supporting motor frame 6 and cutter shaft 7, large belt wheel 2 and milling cutter 8 are installed in cutter shaft 6 two ends, large belt wheel 2 is formed V belt translation with small pulley 4 by synchronous cog belt 3, and common asynchronous moter 5 is arranged on motor rack 6.
Described variable-ratio milling unit head, by changing the number of teeth of large belt wheel 2 and small pulley 4, can change the rotating speed of cutter shaft 6 and milling cutter 8.
The beneficial effects of the utility model are, according to the width in gap to be processed, can change band tooth number, thus change gearratio, reach the object changing milling cutter rotating speed.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Accompanying drawing 1 is variable-ratio milling unit head structural representation.
1. casings in figure, 2. large belt wheel, 3. synchronous cog belt, 4 small pulleys, 5. motor, 6. motor rack, 7. cutter shaft, 8. milling cutter.
Detailed description of the invention
In Fig. 1, described casing 1 is supporting member, supporting motor frame 6 and cutter shaft 7, and large belt wheel 2 and milling cutter 8 are installed in cutter shaft 6 two ends, and large belt wheel 2 is formed V belt translation with small pulley 4 by synchronous cog belt 3, and motor 5 is arranged on motor rack 6.Small pulley 4 drives large belt wheel 2 to form deceleration force amplifier transmission, and the feature of cog belt transmission makes stable drive, reliably, not throws switch.Motor 5 adopts common asynchronous moter, and price is low, and physical dimension is little.
Described variable-ratio milling unit head, by changing the number of teeth of large belt wheel 2 and small pulley 4, can change the rotating speed of cutter shaft 6 and milling cutter 8, to adapt to the requirement of the wide cutting speed of different seam.Can also exchange the position of large belt wheel 2 and small pulley 4, change deceleration transmission is step-up drive, correspondingly high-speed steel milling cutter is replaced by sintex.
Claims (2)
