Abstract
The utility model discloses an upper bearing seat component of a high speed power main shaft. The bearing seat component comprises a bearing seat body, a base and a wear resistant sliding sleeve, wherein a bearing hole used for installation of a bearing is formed in the bearing seat body, and a recess is formed in the inner wall of the bearing hole; the base is detachably connected with the lower end part of the bearing seat body; a shaft core hole through which the shaft core of a power supply main shaft penetrates is formed in the base; the wear resistant sliding sleeve is embedded and arranged in the recess and limited between the top end part of the recess and the upper end surface of the base. Compared with the prior art, the upper bearing seat component has the advantages that the wear resistant sliding sleeve is arrange at the internal of the bearing seat body, so that the wear resistance of the upper bearing seat component of the power main shaft is improved, the service life of the upper bearing seat component is prolonged and the high speed power main shaft has a relatively high operation accuracy; besides, the upper bearing seat component of the high speed power main shaft has the advantage of being simple in structure and convenient to install.
Description
Technical field
The utility model relates to a kind of upper bearing bracket assembly of high-speed electric main shaft.
Background technique
High-speed electric main shaft is normally arranged on bearing block assembly by bearing, and bearing hole and axle core hole are set in the upper bearing bracket of general high-speed electric main shaft, and bearing hole inside is used for installing bearing, and axle core hole is passed for the axle core of high-speed electric main shaft.
High-speed electric main shaft is in when work, and being arranged on bearing in the bearing hole of upper bearing bracket can be along the sliding axially of bearing support, and in sliding process, the hole wall of the bearing hole of the upper bearing bracket that can wear and tear, declines the running precision of high-speed electric main shaft.
Model utility content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of upper bearing bracket assembly of high-speed electric main shaft, and it has advantages of long service life, and can improve the running precision of electric main shaft.
For achieving the above object, the utility model adopts following technological scheme:
A kind of upper bearing bracket assembly of high-speed electric main shaft, comprise bearing support body, base and wear-resisting sliding sleeve, on bearing support body, offer the bearing hole for putting bearing, the inwall of bearing hole is provided with a recess, the dismountable underpart that is connected in bearing support body of base, and the axle core hole that the axle core that offers a power supply main shaft on base passes, wear-resisting sliding sleeve is embedded in recess and is limited between the tip portion of recess and the upper-end surface of base.
On bearing support body and base, be provided with bolt hole, cross-under has a lock bolt that bearing support body and base are fixed together in bolt hole.
The beneficial effects of the utility model are:
Than prior art, the utility model arranges wear-resisting sliding sleeve in bearing support body interior, improve the wear-resisting property of electric main shaft upper bearing bracket assembly, thereby improved the working life of upper bearing bracket assembly, and guaranteed that high-speed electric main shaft has higher running precision.The advantages such as in addition, the utility model also has simple in structure, easy for installation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Wherein: 10, bearing support body; 11, bearing hole; 12, recess; 20, base; 21, axle core hole; 22, lock bolt; 30, wear-resisting sliding sleeve.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
As Fig. 1, shown in 2, for the upper bearing bracket assembly of a kind of high-speed electric main shaft of the present utility model, it comprises bearing support body 10, base 20 and wear-resisting sliding sleeve 30, wherein, on bearing support body 10, offer the bearing hole 11 for putting bearing, the inwall of bearing hole 11 is provided with a recess 12, the dismountable lower end surface that is connected to bearing support body 10 of base 20, on base 20, offer the axle core hole 21 that the axle core of a power supply main shaft passes, axle core hole 21 is coaxial with bearing hole 11, wear-resisting sliding sleeve 30 is embedded in recess 12, and this wear-resisting sliding sleeve 30 is clamped between the top end of recess 12 and the upper-end surface of base 20.
The utility model arranges wear-resisting sliding sleeve 30 in bearing support body 10 inside, in the time that high-speed electric main shaft is worked, bearing slides in the bearing hole 11 of bearing support body 10, because the surface abrasion resistance of wear-resisting sliding sleeve 30 is stronger, therefore, improve the sliding capability of bearing and the running precision of electric main shaft, improved the working life of bearing support body 10.High-speed electric main shaft can normally be worked under different temperatures.Also can, at the interior installation dish of bearing hole 11 spring, be used to bearing that pretightening force is provided, further improve the running precision of high-speed electric main shaft.
In the utility model, on bearing support body 10 and base 20, be provided with bolt hole, cross-under has a lock bolt 22 that bearing support body 10 and base 20 are fixed together in bolt hole.When mounted, first wear-resisting sliding sleeve 30 is arranged on from the bottom to top in the recess 12 of bearing hole 11 inside of bearing support body 10 offering, then base 20 is placed in to the bottom end of bearing support body 10, by lock bolt 22, base 20 is locked on bearing support body 10, while tightening lock bolt 22, can clamp fully wear-resisting sliding sleeve 30; In use, if wear-resisting sliding sleeve 30 has loosening phenomenon, can also be by tightening the fastening wear-resisting sliding sleeve 30 of lock bolt 22.
To one skilled in the art, can be according to technological scheme described above and design, make other various corresponding changes and deformation, and within these all changes and deformation all should belong to the protection domain of the utility model claim.
