Abstract
The utility model relates to an installation tool of the rear oil seal of engine. When the engine is in static state, a fixed disc is fixed to the rear face of a crankshaft by long screws; a pressing sleeve moves axially by the thrust transfer of the twist grip among the pressing sleeve, a bearing sleeve, a thrust bearing and a thrust gasket; when the end of the pressing sleeve touches the end of a back cover plate, the rear oil seal of the crankshaft is under the pressure of the pressing sleeve cone, and can be pressed into given position on the crankshaft cylindrical if stressed uniformly. The rear oil seal pressed by the tool will not have edge trimming, and the installed rear oil seal is reliable in working and is free from oil leakage. The utility model has the advantages of simple structure, easy manufacturing, and remarkable effect. The installation and maintenance is also facilitated as the tool can be applied in the engine crankshaft rear oil seals of various types and sizes.
Description
One, technical field
The utility model relates to engine crankshaft Rear oil seal erecting tools.
Two, background technology
Engine connects power output by the crankshaft rear end output flange of rotation at a high speed with flywheel.In order to prevent lubricating oil splash in the crankcase, leak out the environment that depollutes from crankshaft rear end, usually Rear oil seal must be installed on bent axle.The bent axle Rear oil seal erecting tools of Cai Yonging can only be installed the engine crankshaft Rear oil seal of a certain model in the past, and the rubber Rear oil seal is often cut edge easily when installing, thereby influenced the Rear oil seal sealing property.Adopt the bent axle Rear oil seal erecting tools of the band conical surface side cut problem to be installed, and can be used for the engine crankshaft Rear oil seal installation of multiple gauge size with regard to solving.
Three, summary of the invention
The utility model provides a kind of installation engine crankshaft Rear oil seal instrument.Fixed disk in the Rear oil seal erecting tools is installed on the crankshaft rear end face, and the Rear oil seal cylindrical that is positioned on the outer garden of bent axle is on the gland conical surface, makes the gland conical surface that Rear oil seal is pressed into assigned position on the bent axle by mobile gland.
The utility model is achieved in that a kind of engine band conical surface Rear oil seal erecting tools, fixed disk is fixedly connected with axle, fixed disk is fixedly installed on the crankshaft rear end face by long spiro nail, gland, bearing holder (housing, cover), thrust bearing, Thurst washer and rotary handle are installed in series on axle, gland is between fixed disk and bearing holder (housing, cover), between rotary handle and the axle is thread connection, and Rear oil seal is outside bent axle in garden and the gland between the garden.
Above-mentioned engine band conical surface Rear oil seal erecting tools, the gland end has the gland conical surface.
Adopt the bent axle Rear oil seal erecting tools of the band conical surface side cut problem to be installed, and can be used for the engine crankshaft Rear oil seal installation of multiple gauge size with regard to solving.
Four, description of drawings
Fig. 1 is that engine is installed the Rear oil seal schematic representation of apparatus.
Among the figure, 1 is the gland conical surface, and 2 is gland, and 3 is long spiro nail, and 4 is fixed disk, and 5 is bearing holder (housing, cover), and 6 is thrust bearing, and 7 is Thurst washer, and 8 is rotary handle, and 9 is bent axle, and 10 is Rear oil seal, and 11 is the gland end face, and 12 is axle, and 13 is back shroud.
Five, preferred forms
Preferred forms of the present utility model is provided by following accompanying drawing.
Referring to Fig. 1, under engine static state, the engine crankshaft Rear oil seal 10 that needs are installed places on the outer garden of bent axle in advance, fixed disk 4 and axle 12 are fixedly connected and are one, fixed disk 4 is fixed on the rear end face of engine crankshaft 9 with 2 long spiro nails 3 then, gland 2, bearing holder (housing, cover) 5, thrust bearing 6, Thurst washer 7 and rotary handle 8 are installed in series on axle 12, gland 2 is between fixed disk 4 and bearing holder (housing, cover) 5, rotary handle 8 is a thread connection with axle 12, gland 2, bearing holder (housing, cover) 5, thrust bearing 6, Thurst washer 7 all can be free to slide on axle 12.The axial thrust that when tightening rotary handle 8, produces, by Thurst washer 7, thrust bearing 6, bearing holder (housing, cover) 5 acts on gland 2, making gland 2 produce axially parallel moves, make the Rear oil seal 10 that places in advance on the bent axle 9 outer gardens, be positioned at simultaneously on the gland conical surface 1, when gland 2 moves to gland end face 11 with back shroud 13 plane contact, gland 2 makes Rear oil seal 10 under evenly stressed situation by the gland conical surface 1, promptly is pressed into the assigned position on the outer garden on the bent axle 9.
Engine band conical surface Rear oil seal erecting tools of the present utility model, the rubber Rear oil seal can not cut edge during installation, makes Rear oil seal 10 reliable operations, has prevented leakage of oil.This apparatus structure is simple, and is easily manufactured, and effect is remarkable, and can be used for the engine crankshaft Rear oil seal installation of multiple gauge size, brings convenience to installation and maintenance.
Claims (2)
1, a kind of engine band conical surface Rear oil seal erecting tools, it is characterized in that fixed disk and axle are fixedly connected, fixed disk is fixedly installed on the crankshaft rear end face by long spiro nail, gland, bearing holder (housing, cover), thrust bearing, Thurst washer and rotary handle are installed in series on axle, gland is between fixed disk and bearing holder (housing, cover), between rotary handle and the axle is thread connection, and Rear oil seal is outside bent axle in garden and the gland between the garden.
2, engine band conical surface Rear oil seal erecting tools according to claim 1 is characterized in that the gland end has the gland conical surface.
