Description
technical field:
the utility model relates to a kind of precision bearing system with overload protection.
background technique:
in shafting system, the normal operation of the smooth working of axle system and guaranteeing precision and motor is closely bound up.Shafting system and motor effective is connected just become particularly important, former shafting system adopts main shaft to be directly connected by coupling with motor, this Placement does not reach the torque that should export when axle system carrying large-mass workpiece due to motor, and makes motor cause damage because of overload.
summary of the invention:
the purpose of this utility model is to provide a kind of precision bearing system with overload protection.
above-mentioned object is realized by following technological scheme:
a kind of precision bearing system with overload protection; its composition comprises: driving wheel; described driving wheel is connected with main shaft by screw; described main shaft is connected with friction pad; described friction pad is connected with minor axis by woodruff key; be connected with spring pad on the right side of described friction pad; be connected with spring on the right side of described spring pad; be connected with primary nut on the right side of described spring; described primary nut adopts with minor axis and is threaded; described primary nut is fixed by screw and minor axis, and described minor axis is connected with motor by coupling.
the precision bearing system of described band overload protection, described coupling is connected with minor axis and motor respectively by screw, described friction padinner diameter location has keyway
described driving wheel internal diameter is Φ 15, described spring is that two ends are enclosed also tight and polish Compress Spring, the central diameter of described spring is φ 7.5-φ 15, the helix angle of described spring is 5 °-9 °, described spring pad external diameter is φ 9-φ 17, and described primary nut internal diameter is φ 6-φ 13, and described primary nut external diameter is φ 9-φ 17.
the beneficial effects of the utility model:
1. the utility model adopts friction pad and driving wheel transmitting torque, can effectively avoid causing motor damage because carrying excessive.Increase spring assembly, can effective regulating friction force.By regulating primary nut to adjust spring pressure, making friction pad contact driving wheel and driving main axis.When shafting system carrying workpiece quality is excessive, friction pad will skid with driving wheel, avoid motor to cause damage because of overload with this.
the utility model can make axle system and motor stabilizing run to be more conducive to protect motor simultaneously, to avoid making motor damage decrease debugging security risk because carrying excessive, improve working efficiency.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present utility model.
