Abstract

The utility model relates to a lower bearing inner ring locknut, in particular to a nut mainly used for balancing and correcting a main shaft core to reduce the vibration of a main shaft when rotating. At least two threaded holes (1) are evenly distributed on the end face of a nut body disclosed by the utility model; at least one bolt (4) is arranged in each threaded hole (1); and at least two unthreaded holes (2) are arranged on the end face of the nut body. When the main shaft is balanced and corrected by the lower bearing inner ring locknut, only the number of the bolts needs to be adjusted; materials do not need to be removed by a machining mode, so that equipment is saved. The lower bearing inner ring locknut is capable of increasing the weight at the same position and is also capable of reducing the weight at the same position, so that the dynamic balance and correction is more convenient. The utility model has a more integrated structure and is convenient to popularize and apply.

Description

Ring lock jack panel in a kind of lower bearing

Technical field

The utility model relates to a kind of machining equipment, and specifically a kind of nut is mainly used in the balance correction of main shaft axle core, the vibration when reducing main axis rotation.

Background technique

In the prior art, when balance correction, generally need to deduct the material of mainshaft nut to make to revise the main shaft balance through machining, this is the cost increase of order modification nut just, and increased energy consumption, in addition, the situation that the way of reduction nut material is often wrong to be subtracted occurs, at this moment has only to continue to deduct symmetrical nut material and can reach balance, so the often out-of-flatness of mainshaft nut surface.

Summary of the invention

The utility model relates to ring lock jack panel in a kind of lower bearing, when it makes balance correction at main shaft, only needs to adjust the screw number and gets final product, and does not need to remove material with the mode of machining, has saved equipment; Can increase the weight of at same position, also can make dynamic balance calibration convenient at the same position loss of weight; More completeization of structure is convenient to promote and use.

The utility model technical solution is the nut body at existing ring, the nut body inwall is threaded on the basis of (3), the utility model is furnished with at least two tapped holes (1) particularly in average mark on the end face of nut body, be equipped with at least one screw (4) in each tapped hole (1), the end face of nut body is provided with at least two unthreaded holes (2).

More than on the end face of nut body described in the utility model average mark be furnished with 20 tapped holes (1), be equipped with a screw (4) in each tapped hole (1).

The end face of nut body described in the utility model is provided with six unthreaded holes (2).

The utility model is equal angular uniform many little tapped holes (1) on the end face of collar nut body, on the end face several unthreaded holes (2) are arranged also simultaneously; Block unthreaded hole (2) with setting tool, be fixed on the running shaft by screw thread (3).In the time of need making balance correction, the screw (4) that is screwed into or lays down little quality in tapped hole (1) increases or reduces unbalance mass.

Advantage of the present utility model is:

1, makes balance correction, only need to adjust the screw number and get final product, do not need to remove material, saved equipment with the mode of machining;

2, can increase the weight of at same position, also can make dynamic balance calibration convenient at the same position loss of weight;

3, more completeization of structure can not make rugged to part surface as go the material correction with the mode of machining, be convenient to promote and use.
