Through-hole wall is provided with internal thread, and plug is one to be screwed onto the interior hexagonal holding screw in through hole.
Engine body exterior is provided with the groove of setting for waterproof apron.
The two ends of body overcoat and body junction are provided with O-ring seal.
The beneficial effects of the utility model are:
Than prior art, the utility model can make the direct contact bearing of the temperature-sensing probe of temperature measurer, thereby surveys accurately the temperature of bearing, and under non-working condition, can be by plug shutoff in the through hole of water seal cover, it is easy to use, simple in structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the zoomed-in view at A place in Fig. 1;
Wherein: 10, body; 11, thermometer hole; 12, waterproof apron; 13, groove; 20, axle core; 30, bearing; 40, body overcoat; 41, O-ring seal; 42, installing hole; 50, water seal cover; 51, through hole; 52, plug.
The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:
As shown in Figure 1, 2, temperature measurement structure for a kind of direct-connected main shaft of the present utility model, it comprises body 10, axle core 20, bearing 30,20 cross-under of axle core are in body 10 inside, bearing 30 is between axle core 20 and body 10, it is fixing with axle core 20 that the inwall, inner ring of body 10 is fixed in its outer ring, thereby axle core 20 is articulated on body 10.The fixing body overcoat 40 that is socketed with also in the outside of body 10, the airtight cooperation of outer surface junction of the two ends of this body overcoat 40 and body 10, concrete is, the position that can coordinate with body 10 at body overcoat 40 two ends arranges respectively an O-ring seal 41, between body 10 and body overcoat 40, form one for holding the gap of cooling water, cooling water can be accessed in this gap, to body 10, carries out cooling.On the sidewall of body 10, offer a thermometer hole 11, this thermometer hole 11 is along the radially extension of body 10, its medial extremity is concordant with bearing 30, that is to say, this thermometer hole 11 is radially by the outer surface of body 10, to be extended to the position of the surface engagement of body 10 inner surfaces and bearing 30 outer rings along body 10, on body overcoat 40, offer an installing hole 42, in this installing hole 42, be bolted with a water seal cover 50, between the outer surface of the inner side end of water seal cover 50 and body 10, be provided with a waterproof apron 12, this waterproof apron 12 is folded between the outer surface of body 10 and the inner side end of water seal cover 50, waterproof apron 12 is looped around the periphery of thermometer hole 11, be that the medial extremity of water seal cover 50 is for isolating above-mentioned gap and the thermometer hole 11 that holds cooling water, and after screwing water seal cover 50, the inner side end extruding waterproof apron 12 of water seal cover 50, make waterproof apron 12 that deformation occur, thereby guarantee the sealing of water seal cover 50 inner side ends and body 10 outer surface joints, prevent that the water in above-mentioned gap from entering into thermometer hole 11.On water seal cover 50, be provided with a through hole 51 aliging with thermometer hole 11, that is to say, through hole 51 overlaps with the central shaft of thermometer hole 11, the inner dismountable plug 52 that is connected with of through hole 51, in order to be easy for installation and removal, can offer internal thread at the inwall of through hole 51,52 of plugs can be one to be screwed onto the interior hexagonal holding screw of through hole 51 inside.
