Abstract
The utility model relates to a pulley bearing detaching device, characterized by: include the carrying handle, strike the board and dismantle the roof, the carrying handle with strike board upper surface rigid coupling, surface vertical rigid coupling under dismantling the roof and strikeing the board. Beneficial effect: compared with the prior art, the utility model discloses convenient and fast is dismantled to the bearing, has both solved to be difficult to dismantle the difficulty with what the bar copper directly strikeed pulley bearing inner race traditional approach, guarantees that the bearing is not damaged, can improve work efficiency again, the security of reinforcing dimension guarantor staff work.
Description
Technical field
The utility model belongs to maintenance tool, particularly relates to a kind of pulley bearings provision for disengagement.
Background technology
Along with the continuous increase of China's ports container quantity, operating efficiency and the safety requirements of the maintenance of harbour bank bridge device are more and more higher.Pulley bearings as bank bridge lifting mechanism (ZMHL950-Aa) reaches life cycle, needs to change.Pulley bearings model NJ232EM160*290*48, belongs to thrust roller bearing, and each bearing weight is about 15Kg.Distribution form is duplex bearing, and be provided with spacer ring in the middle of bearing, inner ring bears axial force, and its direction all from inside to outside.Traditional bearing method for dismounting utilizes copper rod to carry out knocking bearing inner race.This kind of method for dismounting not only dismantles difficulty, effort of taking a lot of work, and efficiency is very low, and also brings certain impact to self handling safety of repair and maintenance personnel.The work of harbour machinery repair and maintenance urgently improves maintenance tool further, to adapt to actual production demand, shortens maintenance cycle.
Utility model content
The utility model is to overcome deficiency of the prior art, provides a kind of pulley bearings provision for disengagement, abandons the traditional method for dismounting knocking bearing inner race with copper rod, drastically increases operating efficiency, in turn enhance the security of repair and maintenance person works.
The utility model for achieving the above object, be achieved through the following technical solutions, a kind of pulley bearings provision for disengagement, is characterized in that: comprise carrying handle, tapping board and dismounting top board, described carrying handle and tapping board upper surface affixed, described dismounting top board is vertical with tapping board lower surface affixed.
Described tapping board upper surface two ends are connected with retainer ring, described retainer ring are mounted with the chain type carrying handle formation chain type carrying handle of two ends with hook.
Described tapping board is that vertical centering is affixed with dismounting top board.
Width≤dismounting bearing inner race the bore dia of described dismounting top board, the height > of dismounting top board dismantles the thickness of duplex bearing.
Beneficial effect: compared with prior art, the utility model bearing removal is convenient and swift, both solved with copper rod directly knock pulley bearings inner ring conventional method be difficult to dismounting difficulty, ensure bearing not damaged, can increase work efficiency again, strengthen the security of repair and maintenance person works.

Detailed description of the invention
Below in conjunction with preferred embodiment, to the detailed description of the invention provided according to the utility model, details are as follows: embodiment
Refer to accompanying drawing, present embodiments provide a kind of pulley bearings provision for disengagement, comprise carrying handle, tapping board 2 and dismounting top board 3, described carrying handle and tapping board upper surface affixed, described dismounting top board is vertical with tapping board lower surface affixed.Described tapping board is that vertical centering is affixed with dismounting top board.Width≤dismounting bearing inner race the bore dia of described dismounting top board, the height > of dismounting top board dismantles the thickness of duplex bearing.
The present embodiment preferred version is that described tapping board upper surface two ends are connected with retainer ring 4, described retainer ring is mounted with the chain type carrying handle formation chain type carrying handle 1 of two ends with hook 5.
The course of work
The present embodiment is to dismantle ZMHL950-Aa pulley bearings, after opening pulley transparent cover, by on pulley placing flat two sleepers, with chain type carrying handle, tapping board is placed on pulley bearings inner ring, dismounting top board inserts in upper bearing inner ring hole, pulley cone spacer and lower bearing inner ring hole, directly knock tapping board with hammer, lower bearing, cone spacer, upper bearing inner ring are easy to just be removed; Then by pulley placing flat in the other direction on two sleepers, be encased on bearing by former for upper bearing inner ring direction, be placed on pulley bearings inner ring with chain type carrying handle by tapping board, dismounting top board inserts in bearing inner race hole, knock tapping board with hammer, bearing is easy to be removed.The provision for disengagement of ZMHL950-Aa pulley bearings not only drastically increases operating efficiency, in turn enhances the security of repair and maintenance person works.
Above-mentioned detailed description of this kind of pulley bearings provision for disengagement being carried out with reference to embodiment; illustrative instead of determinate; several embodiments can be listed according to institute's limited range; therefore in the change do not departed under the utility model general plotting and amendment, should belong within protection domain of the present utility model.
