Description
Technical field
The present invention relates to a kind of engine component, specifically, relate to a kind of motor thrust bearing shell.
Background technique
Engine crankshaft thrust plate is the one of Bearing in Internal Combustion Engine, mainly plays a part bent axle axially support in motor, in ensureing that bent axle circumferentially rotates, stops bent axle axial float.Crankshaft thrust collar is installed on the corresponding position of crankshaft thrust shelves, directly contacts the wearing and tearing that cause for what prevent bent axle and body.Crankshaft thrust collar must ensure not interfere, do not get loose in the time of assembling.Bearing shell bearing shell is sliding bearing and the tactile part that is coupling, very smooth, generally makes with high-abrasive materials such as bronze, antifriction alloys, under special circumstances, can make with timber, plastics or rubber.Also be " axle bush ", be shaped as the semi-cylindrical of watt shape, the function of its function is the bearing shell (comprising the part on axle) that support rotates, and preserves running accuracy, reduces the friction and wear between axle and supporting.Normally, thrust plate and bearing shell are installed separately, and have caused the complexity of installing, and existing crankshaft thrust collar be to be connected with thrust main bearing seat by pin in addition, installation complexity, move unreliable and, lubricate not good problem.
Summary of the invention
The present invention is directed to existing crankshaft thrust collar, install complicated, move unreliable and, lubricated not good problem, provides a kind of motor thrust bearing shell, to address the above problem.
The solution of the present invention is by such realization: construct a kind of motor thrust bearing shell, comprise thrust plate and bearing shell, described thrust plate and bearing shell are arranged in main bearing cap, described thrust plate and bearing shell are that an overall stamping part forms thrust bearing shell, thrust bearing shell is divided into thrust bearing shell and lower thrust bearing shell, be provided with into oilhole at upper thrust bearing shell and lower thrust bearing shell joint, described enter oilhole side be connected with the oil channel that is arranged on main bearing cap, also be provided with oil hole at main bearing cap lower position, cross oil hole through main bearing cap and lower thrust bearing shell side surface, described oil channel is connected with mistake oil hole by the oil duct of its underpart.
The solution of the present invention technician's principle is: adopt a kind of lubrication system architecture processed to solve a difficult problem of the prior art, first, thrust plate and bearing shell are struck out to integral piece, realize effect easy to assembly, secondly, by integral piece thrust bearing shell is divided into upper and lower two-part, by machine oil is introduced into oilhole, final two sides of lubricating thrust bearing shell from making machine oil can pass through oil hole, realizes lubrication effect.
In the present invention, as further improvement, described upper thrust bearing shell place is provided with main oil-in, described main oil-in is by leading the way and entering oilhole and be connected in upper thrust bearing shell, as further improvement, for the internal surface that makes thrust bearing shell also can be lubricated, can be provided with at thrust bearing shell place main oil-in is set, thereby and by leading the way, machine oil is introduced into oilhole, realize overall lubrication effect.
In the present invention, as further improvement, described upper thrust bearing shell and lower thrust bearing shell are all fixed in main bearing cap by fixed block, and its fixed block can be via hole nail, fixing nail or fixed structure that some are conventional etc.
In the present invention, as preferred version, described in enter oilhole and can be arranged in thrust bearing shell and lower thrust bearing shell, it is shaped as semicircle.
The invention has the beneficial effects as follows:
1. the present invention is simple in structure, reliability is high, and processing technology is simple, and the mode that more existing crankshaft thrust collar adopts pin to be connected with main bearing has been simplified a lot.
2. the present invention, by just using the mode in nail hole, has increased flowing of lubricant oil, greatly improves the effect of lubricated workpiece, and the life cycle of bearing is greatly strengthened.
3. the present invention processes simply, can in original equipment Foundations, improve, and good manufacturability, is convenient to use and promotes
