Abstract
The utility model discloses a gear clearance eliminating mechanism for a heavy-duty CNC roll grinder. The mechanism is characterized in that the mechanism takes a tool rest body as a box body; two sets of speed reducers of right-angle structure are installed on the box body in parallel; the rear parts of the two sets of speed reducers are connected with two servo motors; the lower parts of the speed reducers are connected, fixed and locked on a connection body by bolts; a gear is connected and locked with the connection body by bolts; the gear is meshed with a transmission rack; and the transmission rack is installed on the side close to a guide rail. The mechanism has the following beneficial effects that: the aim of clearance elimination is achieved by adopting the start time difference of the double-servo-drive gear clearance eliminating mechanism and the electrical control motor and higher transmission efficiency and precision retaining property are achieved.
Description
Technical field
The utility model relates to a kind of NC heavy roll grinder gear clearance elimination mechanism.
Background technology
Along with the continuous progress of mechanical industry, CNC heavy-duty horizontal lathe is also increasingly high to the requirement of transmission accuracy, and existing single servo gear anti-backlash mechanism exists the adjustment difficulty, the deficiency that precision stability is bad, and it is very inconvenient to operate.Existing single servo gear anti-backlash mechanism also exists complex structure, and volume is too huge, usually can cause mounting structure limited, does not more and more suit to use in numerical control high precision overloading machine tool field.
Summary of the invention
The technical problem that the utility model will solve is to provide a kind of NC heavy roll grinder gear clearance elimination mechanism, and this device tool efficient is high, and stable accuracy, adjustment are easily and the advantage of saving the space.
The technical scheme of the utility model is: this mechanism is casing with the tool-post structure, and the decelerator of two cover right-angle structures is installed in parallel on the casing, and the rear portion of two cover decelerators connects with two servomotors respectively; The bottom of decelerator is fixed and is locked on the connected body through screw attachment; Gear is connected with connected body through screw and locks, and gear is meshed with driving rack, and driving rack is installed in the side near guiding rail.
The beneficial effect of the utility model is: gear clearance elimination mechanism and electrical control electric motor starting time difference through adopting two servo-drive have been realized the purpose in crack that disappears, and have realized higher transmission efficiency and precision stability ability.
The utility model is under the jurisdiction of the great special project of national science and technology, project number: 2009ZX04002-072.
