Abstract
The utility model discloses a kind of motor guide shoe jackscrew device, it comprises: jackscrew bar, bolt, locknut, guide shoe frame; It is characterized in that: described jackscrew bar is from left to right provided with push rod head, right-handed thread bar, left hand thread bar, spanner handle four part in turn; Described locknut edge is symmetrically arranged with two tapped through holes.By implementing above technical scheme, there is following technique effect: an overall existing right-handed thread of jackscrew bar has left hand thread again, wants generation and moves axially, guide shoe frame must be made to separate with locknut.When as long as no human intervention, jackscrew bar loosens never, thoroughly can eliminate the problem that guide shoe oil clearance occurs to increase in running.
Description
Technical field
The utility model relates to vertical machine technical field, particularly a kind of motor guide shoe jackscrew device.
Background technology
The guide bearing of large-scale vertical circulating pump motor is sliding bearing, is called for short guide shoe; Guide shoe be up and down on the lower supporting plate and top board spacing, horizontal direction is spacing by the jackscrew of guide shoe back of the body arc, and by jackscrew adjustment guide shoe oil clearance, guide shoe jackscrew passes to axial force locking by two screws by pressing plate, or pass through nut-locking.Motor will produce vibration when running, time can weaken to for a long time the coupling mechanism force of guide shoe jackscrew, guide shoe jackscrew will be there is like this loosen, guide shoe oil clearance is increased, motor oscillating increases, can vicious circle be formed not in time if find, finally cause motor rotor core and stator iron core to touch the serious accident of mill.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of motor guide shoe jackscrew device is provided, can thoroughly eliminate under any state of motor to cause because guide shoe oil clearance is excessive motor oscillating large and even rotor and stator iron core touch the accidents such as mill, this apparatus structure is simple, reliable.
To achieve these goals, the utility model provides following technical scheme: a kind of motor guide shoe jackscrew device, and it comprises: jackscrew bar, bolt, locknut, guide shoe frame; It is characterized in that: described jackscrew bar is from left to right provided with push rod head, right-handed thread bar, left hand thread bar, spanner handle four part in turn; Described locknut edge is symmetrically arranged with two tapped through holes; Described right-handed thread bar is threaded with guide shoe frame, left hand thread bar is connected with locknut, after guide shoe oil clearance is adjusted, two key screw guide shoe framves and the fastening one of locknut can be passed through, and pass to guide shoe jackscrew axial locking power by locknut, because an overall existing right-handed thread of jackscrew bar has left hand thread again, want generation and move axially, guide shoe frame must be made to separate with locknut.
By implementing above technical scheme, there is following technique effect: an overall existing right-handed thread of jackscrew bar has left hand thread again, wants generation and moves axially, guide shoe frame must be made to separate with locknut.When as long as no human intervention, jackscrew bar loosens never, thoroughly can eliminate the problem that guide shoe oil clearance occurs to increase in running.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
In order to better understand the technical solution of the utility model, describe below in conjunction with accompanying drawing the embodiment that the utility model provides in detail.
Fig. 1 is pre-program of the present utility model, and which show a kind of motor guide shoe jackscrew device, it comprises: jackscrew bar, bolt 4, locknut 5, guide shoe frame 3; It is characterized in that: described jackscrew bar is from left to right provided with push rod head 1, right-handed thread bar 2, left hand thread bar 6, spanner handle 7 four part in turn; Described locknut 5 edge is symmetrically arranged with two tapped through holes; Described right-handed thread bar 2 is threaded with guide shoe frame 3, left hand thread bar 6 is connected with locknut 5, after guide shoe oil clearance is adjusted, can by two screws 4 guide shoe frame 3 and the fastening one of locknut 5, and pass to guide shoe jackscrew axial locking power by locknut 5, because an overall existing right-handed thread of jackscrew bar has left hand thread again, want generation and move axially, guide shoe frame must be made to separate with locknut.
Above to a kind of motor guide shoe jackscrew device that the utility model embodiment provides, be described in detail, for one of ordinary skill in the art, according to the thought of the utility model embodiment, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
