Abstract
The utility model discloses a hydraulic nut auxiliary device capable of performing press mounting on a shaft without connecting threads and a part the inner hole of which is provided with taper, which comprises a hydraulic nut (1), and is characterized in that the hydraulic nut auxiliary device is provided with a support (3) which is connected with the hydraulic nut (1), wherein a sleeve (4) is arranged between the support (3) and the hydraulic nut (1). The hydraulic nut auxiliary device has a simple structure, low cost and stable and reliable performance, is easy to process and manufacture, is favorable for promotion and application, not only solves the problem that a driving hole is difficult to center but also is more favorable for manual operation because a hydraulic nut body is provided with a wrench groove, and can solve the problem of performing press mounting on the shaft without connecting threads and the part the inner hole of which is provided with taper.
Description
Technical field:
The utility model relates to a kind of hydraulic nut, specifically a kind of hydraulic nut servicing unit.
Background technology:
In industries such as machinery, metallurgy, oil, chemical industry, need utilize the often frequent dismounting of hydraulic nut, above big specification nut or the bearing of fastening main shaft M125.But it is then powerless to press-fiting of the part that do not have to connect thread spindle and interior pore area tapering.
Summary of the invention:
The purpose of this utility model provide a kind of can be to do not have connecting the hydraulic nut servicing unit that thread spindle and interior pore area tapering part press-fit.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of hydraulic nut servicing unit, and it comprises hydraulic nut, is characterized in being provided with the bearing that is connected with hydraulic nut, is provided with sleeve between bearing and the hydraulic nut.
The utility model has the tapering chamfering at sleeve endoporus front end.
The utility model is provided with the spanner groove on hydraulic nut.
Owing to adopt technique scheme, the utility model has been realized goal of the invention preferably, apparatus structure is simple, processing and manufacturing is easy, cost is low, stable and reliable for performance, be beneficial to and apply because the hydraulic nut body has the spanner groove, solved not only that driving hole is difficult for aligning between topic, and be more conducive to workman's operation, can solve by this device does not have press-fiting of connection thread spindle part and interior pore area tapering part.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
By accompanying drawing as can be known, a kind of hydraulic nut servicing unit, it comprises hydraulic nut 1, is characterized in being provided with the bearing 3 that is connected with hydraulic nut 1, is provided with sleeve 4 between bearing 3 and the hydraulic nut 1.
The utility model has the tapering chamfering at sleeve 4 endoporus front ends.
The utility model is provided with the spanner groove on hydraulic nut 1.
When the utility model uses, when in banbury, needing to be installed in bearing on the armature spindle, earlier bearing 7 is enclosed within on the armature spindle 6, bearing 3 is fixed on the end face of armature spindle 6 with soket head cap screw 5 then, cover upper bush 4 is installed in hydraulic nut 1 on the bearing 3 again.Stick into the spanner groove by spanner then, rotating hydraulic nut 1 passes to sleeve 4 by piston ring 2 with power, when sleeve 4 surfaces touch bearing 7 inner peripheral surface, promote bearing 7 inner rings and travel forward, thereby the end-play of adjusting bearing 7 makes it to be in optimum Working along armature spindle 4.
