Hold lid and main bearing seat combined mechanism.
What the technical solution of the utility model was realized in：A kind of high strength main bearing cap and main bearing seat combination machine
Structure, it is characterised in that：Including the main beating cap being movably connected and main bearing seat, and for connecting main beating cap and master
Bearing block and the protective sleeve played a protective role to bolt；The main beating cap is provided with upper screwed hole, the main bearing seat
Lower screwed hole is provided with, the upper screwed hole and lower screwed hole eyelet are relative；The upper screwed hole epimere diameter is equal to lower screw thread
Hole hypomere diameter, the upper screwed hole hypomere is located at main beating cap and main bearing seat joint, and the lower screwed hole epimere is located at
Main beating cap and main bearing seat joint, the upper screwed hole hypomere diameter are equal to lower screwed hole epimere diameter, the upper screw thread
Hole hypomere diameter is more than upper screwed hole epimere diameter；Upper screwed hole hypomere diameter is more than upper screwed hole upper portion and lower screw thread
Hole epimere diameter is more than lower screwed hole hypomere part, forms annular gap；The protective sleeve is provided with external screw thread and internal thread, institute
State protective sleeve and upper screwed hole and lower screwed hole are connected by external screw thread；The protective sleeve internal thread connecting bolt.
As preferred technical scheme, cushion pad is placed with the annular gap.
By adopting the above-described technical solution, the utility model has beneficial effect following prominent：
1st, it will not be impacted under the protective effect of protective sleeve by active force, particularly main beating cap and main bearing seat
This section of bolt of junction, one is connected into annular gap, cushion pad and protective sleeve by main beating cap and main bearing seat
In the presence of the technical scheme such as overall, it is to avoid this section of bolt deforms or phenomenon of rupture.
2nd, two independent individual main beating cap and main bearing seat are linked together by protective sleeve, formation one is whole
Body, makes main beating cap and main bearing seat junction not be fully disconnected, when main beating cap bears the active force of horizontal direction, main
Bearing cap and main bearing seat are due to combining, so being not in relative displacement.
