Abstract
The utility model relates to a kind of marine propeller main shaft thrust-bearing securing means.Specifically, be for blocking thrust-bearing, preventing the securing means of thrust-bearing generation axial float.It comprises impeller shaft, and the adjacent end place cover of impeller shaft has thrust-bearing, and the impeller shaft end outside thrust-bearing is useful in the locking nut blocking thrust-bearing.Be characterized in that the exterior edge face circumferencial direction of described locking nut is evenly equipped with radial groove, the outer end circumferencial direction of described impeller shaft is evenly equipped with axial groove, and the quantity of described axial groove is less than radial groove, and the groove width of described axial groove and the groove width of radial groove suitable.Positioning key block is all connected with in described axial groove and corresponding radial groove.Adopt this securing means, comparatively large for impact force, the marine propeller main shaft thrust-bearing strong adaptability that rotating forward, reversion or starting duty are larger, failure rate is low.
Description
Technical field
The utility model relates to a kind of bearing locking mechanism.Specifically, be for blocking thrust-bearing, preventing the securing means of thrust-bearing generation axial float, what be particularly useful for the thrust-bearing of Ship Propeling pump spindle nose is fastening.
Background technique
All know, in order to block thrust-bearing, prevent thrust-bearing generation axial float, to be all furnished with thrust-bearing securing means at Ship Propeling pump spindle nose at Ship Propeling pump production field.Traditional securing means comprises impeller shaft, and the adjacent end place cover of impeller shaft has thrust-bearing, the impeller shaft end cylindrical outside thrust-bearing is processed with screw thread, impeller shaft end cylindrical has the locking nut for blocking thrust-bearing by this screwed.Wherein, on the impeller shaft between locking nut and thrust-bearing, cover has locked spacer.Described locked spacer comprises an annular lamina, the inner circle of annular lamina is processed with footpath inwardly protruding, and corresponding impeller shaft end cylindrical is processed with axial notch, and under installment state, described footpath inwardly protruding is inserted in axial notch.The cylindrical offside of described annular lamina is processed with axial projection, that angle head cylindrical offside that described locking nut is adjacent with this axial projection is processed with axial groove, described axial groove is equal with axial raised quantity and corresponding, under installment state, described axial projection embeds in corresponding axial groove, utilize coordinating between axial projection with corresponding axial groove, realize the fastening of locking nut.Because above-mentioned securing means utilizes coordinating between axial projection with corresponding axial groove to realize the fastening of locking nut, footpath inwardly protruding in annular lamina inner circle on locked spacer can rupture when being subject to larger impact force, cause loosening or locking phenomenon of thrust-bearing, mechanical failure occurs.Therefore, above-mentioned securing means is comparatively large for impact force, the marine propeller main shaft thrust-bearing that rotating forward, reversion or starting duty are larger, and adaptability is poor, and rate of fault is high.
Model utility content
Problem to be solved in the utility model is to provide a kind of marine propeller main shaft thrust-bearing securing means.Adopt this securing means, comparatively large for impact force, the marine propeller main shaft thrust-bearing strong adaptability that rotating forward, reversion or starting duty are larger, failure rate is low.
The problems referred to above to be solved in the utility model realize by with technological scheme:
Marine propeller main shaft thrust-bearing securing means of the present utility model comprises impeller shaft, and the adjacent end place cover of impeller shaft has thrust-bearing, and the impeller shaft end outside thrust-bearing is useful in the locking nut blocking thrust-bearing.Be characterized in that the exterior edge face circumferencial direction of described locking nut is evenly equipped with radial groove, the outer end circumferencial direction of described impeller shaft is evenly equipped with axial groove, and the quantity of described axial groove is less than radial groove, and the groove width of described axial groove and the groove width of radial groove suitable.Positioning key block is all connected with in described axial groove and corresponding radial groove.
Wherein, the bottom land of described radial groove all has axial screw, described positioning key block all has axial hole, described axial hole corresponding with axial screw and the two between be furnished with clamping bolt.
As can be seen from the above scheme, because the exterior edge face circumferencial direction of described locking nut is evenly equipped with radial groove, the outer end circumferencial direction of described impeller shaft is evenly equipped with axial groove, the quantity of described axial groove is less than radial groove, and the groove width of described axial groove and the groove width of radial groove suitable, be all connected with positioning key block in axial groove and corresponding radial groove.With the cooperation utilized in background technique between axial projection with corresponding axial groove to realize locking nut fastening compared with, greatly can improve adaptability, reduce rate of fault.
Accompanying drawing explanation
Fig. 1 is marine propeller main shaft thrust-bearing securing means structural representation of the present utility model;
Fig. 2 is that schematic diagram is looked on a left side of Fig. 1.
Embodiment
As depicted in figs. 1 and 2, marine propeller main shaft thrust-bearing securing means of the present utility model comprises impeller shaft 2, the adjacent end place cover of impeller shaft 2 has thrust-bearing 4, and impeller shaft 2 end outside thrust-bearing 4 is provided with the locking nut 3 for blocking thrust-bearing 4.The exterior edge face circumferencial direction of described locking nut 3 is evenly equipped with radial groove, the outer end circumferencial direction of described impeller shaft 2 is evenly equipped with axial groove 5, the quantity of described axial groove 5 is four and is less than the quantity of radial groove, the groove width of described axial groove 5 and the groove width of radial groove suitable.Positioning key block 1 is all connected with in described axial groove 5 and corresponding radial groove.
Wherein, the bottom land of described radial groove is all processed with axial screw, described positioning key block 1 is all processed with axial hole, described axial hole corresponding with axial screw and the two between be all furnished with clamping bolt 6.By tightening clamping bolt 6, the circumference that can realize between thrust-bearing and marine propeller main shaft is fastening.
