Abstract
A mounting tool for an engine crankshaft front oil seal is characterized in that a keyway protecting sleeve is in sliding connection with a crankshaft front end journal, an intermediate mandrel is in threaded connection with the end face of the crankshaft front end journal, a positioning pressing sleeve and a pressing handle are positioned on the intermediate mandrel, the positioning pressing sleeve is capable of freely sliding on the outer circumferential surfaces of the crankshaft front end journal and the intermediate mandrel, the pressing handle is in threaded connection with the intermediate mandrel, the end face of the positioning pressing sleeve is tightly pressed to a plane of a crankshaft front end gear chamber cover by screwing up the pressing handle, and the end face of the positioning pressing sleeve keeps contact with the crankshaft front oil seal. The mounting tool can ensure the mounting position of the crankshaft front oil seal to meet design requirements and prevent the crankshaft front oil seal from being damaged, and accordingly, oil leakage of the crankshaft front oil seal can be prevented, energy-saving and environment-friendly performances of a diesel engine are optimized, and operation is quite convenient.
Description
Technical field
The utility model relates to engine crankshaft Front oil seal erecting tools.
Background technology
During the engine assembling, the bent axle Front oil seal is directly pushed the crankshaft front end axle journal with hand, the easy scratch Front oil seal of crankshaft front end axle journal keyway bore area, and be difficult to Front oil seal is pushed into the tram, can cause the frequent leakage of oil in bent axle Front oil seal place.
Summary of the invention
The technical problem that the utility model will solve provides a kind of engine crankshaft Front oil seal installation special tool, guarantees bent axle Front oil seal assembly quality.
The utility model is achieved in that engine crankshaft Front oil seal erecting tools; Keyway protective sleeve and crankshaft front end axle journal are for being slidingly connected; With being threaded, location clamping sleeve and pressing handle are positioned on the mandrel of centre on middle mandrel and the crankshaft front end axle journal end face, and locating clamping sleeve can be free to slide on the face of the outer garden of crankshaft front end axle journal and middle mandrel; Pressing handle and middle mandrel are with being threaded; Oil sealing location clamping sleeve is compacted to the end face of locating clamping sleeve on the crankshaft front end gear chamber case plane through tightening pressing handle, and the end face and the bent axle Front oil seal of location clamping sleeve keep in touch.
Because this erecting tools can guarantee that bent axle Front oil seal installation site adheres to specification with injury-free, therefore not only can prevent bent axle Front oil seal oil leakage phenomenon, the energy-conservation and environmental-protecting performance of Optimization of Diesel Engine, and also easy to operate.
Description of drawings
Fig. 1 is an engine crankshaft Front oil seal assembling keyway protective sleeve sketch map.
Fig. 2 is an engine crankshaft Front oil seal assembling specific purpose tool sketch map.
Among the figure, 1 is crankshaft front end gear chamber case, and 2 is the bent axle Front oil seal, and 3 is the crankshaft front end axle journal, and 4 is middle mandrel, and 5 are the location clamping sleeve, and 6 is pressing handle, and 7 is the axle journal keyway, and 8 is the keyway protective sleeve.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Like Fig. 1, shown in 2; Engine crankshaft Front oil seal assembly tool; On crankshaft front end axle journal 3, with hand bent axle Front oil seal 2 is pushed the position that surpasses axle journal keyway 7 on the crankshaft front end axle journal 3 through keyway protective sleeve 8, avoid the directly bore area of contact scratch bent axle Front oil seal 2 of axle journal keyway 7.Take off keyway protective sleeve 8; Be connected with the M16 left-hand thread on middle mandrel 4 and crankshaft front end axle journal 3 end faces; Location clamping sleeve 5 is positioned on the middle mandrel 4 with pressing handle 6; Location clamping sleeve 5 and crankshaft front end axle journal 3 and middle mandrel 4 are for being slidingly connected; Pressing handle 6 is threaded with middle mandrel 4 usefulness, and oil sealing location clamping sleeve 5 will locate the end face of clamping sleeve 5 and be compacted on crankshaft front end gear chamber case 1 plane through being screwed into pressing handle 6, and assurance bent axle Front oil seal 2 can be installed on the tram of crankshaft front end axle journal 3.
Because this erecting tools can guarantee that bent axle Front oil seal 2 installation sites adhere to specification with injury-free, therefore not only can prevent bent axle Front oil seal oil leakage phenomenon, the energy-conservation and environmental-protecting performance of Optimization of Diesel Engine, and also easy to operate.
