Description
Technical field
The utility model relates to a kind of spiral bevel gear grinding machine and uses eccentric main axis, is meant that especially a kind of spiral bevel gear grinding machine uses the high speed eccentric main axis; Belong to the gear machining apparatus preparing technical field.
Background technology
It is to come the grinding forming method bull wheel with having eccentric grinding spindle for the eccentric main axis of spiral bevel gear grinding machine bed (Wa Guli mechanism); The eccentric adjusting sleeve that eccentric throw is 0.15～0.20mm promptly is installed on grinding wheel spindle; Roll flute adds man-hour, in the time of the grinding wheel spindle rotation, also revolves round the sun with eccentric adjusting sleeve; The eccentric motion that to produce an offset be 0.15～0.20mm to be reaching creep feed grinding, thereby makes the emery wheel and the teeth groove flank of tooth produce contacting of clearance-type.Grind off grinding allowance along the tooth length direction during grinding, in emery wheel axial feed teeth groove process, emery wheel along whole tooth surface wide replace between gear teeth convex surface and concave surface, implement grinding.The eccentric gap that produces can constantly get into by the grinding flank of tooth cooling fluid and does not burn, can reach maximum grinding and feeding amount simultaneously as far as possible.This method for grinding is: at first crush grinding to full-depth tooth is dark, and emery wheel paused 1～2 second in short-term in the full-depth tooth depths, carried out grinding along the tooth length direction then.
Eccentric main axis (Wa Guli mechanism) provides lubricated for emery wheel; The heat that has dissipated and produced in the process; The grinding flank of tooth can not burnt, can reach maximum metal removal factor simultaneously as far as possible, secondly; The length of contact zone has been shortened in this creep feed grinding effectively, has prevented that abrasive dust from stopping up the micropore of wheel face and further having reduced the temperature of grinding area.
The eccentric main axis of existing spiral bevel gear grinding machine bed during fabrication; Usually only main shaft is carried out dynamic balance calibration; And be that the eccentric shaft of 0.15～0.20mm does not carry out dynamic balance calibration to eccentric throw, therefore, eccentric main axis is when actual motion; The eccentric main axis rotating speed below 1300rpm, can be realized running well usually.But when the eccentric main axis rotating speed surpassed 1300rpm, because the effect of eccentric main axis rotary inertia causes the current fluctuation of eccentric main axis drive motors very big, temperature sharply rose, and when serious, can send a telegraph machine burning and ruin.It is too high to cause grinding wheel spindle speed not to be provided with owing to the eccentric main axis rotating speed is low excessively; Thereby restricted the further lifting of grinding efficiency and grinding quality; This problem can not get good solution for a long time, becomes eccentric main axis (Wa Guli mechanism) bottleneck of application development on the spiral bevel gear grinding machine bed.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art and provides a kind of spiral bevel gear grinding machine steady, that the speed of service is high that turns round to use the high speed eccentric main axis.
To be existing spiral bevel gear grinding machine with the high speed eccentric main axis be provided with the dynamic balance weight piece with at least one parts in the eccentric shaft body of eccentric main axis, eccentric shaft travelling gear, eccentric shaft bearing compression plate, the eccentric shaft bearing spacer to a kind of spiral bevel gear grinding machine of the utility model.
In the utility model, said eccentric shaft travelling gear, eccentric shaft bearing compression plate, eccentric shaft bearing spacer are connected with said eccentric shaft body-fixed, run-in synchronism.
In the utility model, said dynamic balance weight piece is arranged on said eccentric shaft body or the said eccentric shaft bearing spacer periphery; Or be arranged on said eccentric shaft travelling gear, the eccentric shaft bearing compression plate excircle or on its both sides nose circle face.
The utility model is owing to adopt said structure; Be connected with said eccentric shaft body or with said eccentric shaft body-fixed, synchronous operated eccentric shaft travelling gear, eccentric shaft bearing compression plate, eccentric shaft bearing spacer be provided with the dynamic balance weight piece; Can effectively overcome because the dynamic unbalance inertia of the spiral bevel gear grinding machine that out-of-balance force caused that the offset 0.15～0.20mm of eccentric main axis causes when running up with eccentric main axis; Thereby; Spiral bevel gear grinding machine is brought up to more than the 1500rpm with the rotating speed of eccentric main axis, and the eccentric main axis drive motors operates steadily, current stabilization.Effectively improve spiral bevel gear grinding machine grinding wheel spindle speed, and then improve the grinding efficiency and the grinding quality of spiral bevel gear grinding machine.
In sum, the utility model is rational in infrastructure, running is steady, the speed of service is high, can effectively improve spiral bevel gear grinding machine grinding wheel spindle speed, and then improves the grinding efficiency and the grinding quality of spiral bevel gear grinding machine.Be suitable for industrial applications.
