As a preferred technical scheme of the utility model, first threaded rod is the annular with second threaded rod shape, the length of first threaded rod is greater than the length of second threaded rod, because bearing body itself adsorbs lubricating oil, so lubricating oil need not be placed too much, because thick cotton matter is slim and graceful, and need give sound insulation effectually, so the second threaded rod is shorter.
As an optimal technical scheme of the utility model, thick cotton is sound barrier material makes, when sound transmission, through thick cotton isolated, less sound transmission influences patient with reducing.
As a preferred technical scheme of the utility model, the center of top cap and bottom is hollow, and the diameter value is greater than the diameter value of through-hole, and when the output shaft was joined in marriage with the bearing body, at first need pass the middle part of bearing body, because the diameter at top cap and bottom middle part is greater than the diameter of through-hole, so can not hinder its work and cooperation when passing and the during operation.
As a preferred technical scheme of the utility model, the maximum diameter value of top cap and bottom is less than bearing body top surface diameter value, when carrying out the work cooperation, because the diameter value of top cap and bottom is less than the top surface of bearing body and the diameter value of bottom surface, so can not influence or contact other position face influences work.
Compared with the prior art, the beneficial effects of the utility model are as follows:
1. the utility model discloses a unscrew the top cap, at this moment, the rotation of top cap can drive first threaded rod and rotate together, first threaded rod can break away from first thread groove this moment, break away from the back completely as first threaded rod, at this moment toward the bottom of first thread groove again, the inside department of bearing body pours suitable lubricating oil, after pouring into, again twist back first thread groove and tighten the top cap with the first threaded rod on top cap and the top cap in, the bearing body will produce oil at the self of bearing body at the during operation, the oil that oozes out will reach lubricated effect, work for a long time, lubricating oil can carry out the fuel feeding to the bearing body, relative prior art, so under the work of last long time can not appear, the bearing body has not provided lubricating oil, and lead to not having caused the wearing and tearing to the output shaft surface under the lubricated condition.
2. The utility model discloses a unscrew the bottom, at this moment, the rotation of bottom can drive the second threaded rod and rotate together, the second threaded rod can break away from the second thread groove this moment, at this moment, the top toward the second thread groove again, proper amount thick cotton is added to the inside department of bearing body, after adding, again screw back the second threaded rod on bottom and the bottom in the second thread groove and screw up the bottom, the sound that sends when bearing body work passes through thick cotton filtration, reduce to the degree that does not influence patient's rest, relative prior art, the noise that has avoided sending when oiliness bearing and output shaft cooperation work influences patient's rest.
