Abstract
The utility model discloses an oil blanket behind engine, the characteristic is that pressure equipment cover and uide bushing fuse through the pressure equipment bolt. The plane degree is had relatively high expectations during the oil blanket behind engine installation, sheathe the oil blanket card in the pressure equipment of oil blanket behind engine mounting tool, the bent axle major part is aimed at to the uide bushing, 3 pneumatic wrench twists the big overhead screw of bent axle for the clamp bolt, utilize the power of screwing up and direction of clamp bolt, compress tightly the laminating with uide bushing and bent axle major part, till rotation pressure equipment bolt extremely can not rotate, the oil blanket was pressed to the suitable position of bent axle this moment, unscrew pneumatic wrench for the clamp bolt at last and withdraw from, twist the clamp bolt with pneumatic wrench, take out the oil blanket behind engine mounting tool.
Description
Technical field
The utility model belongs to engine art, especially a kind of engine Rear oil seal.
Background technology
Assemble in industry at engine (diesel engine), in assembling process, need the air-tightness ensureing engine Rear oil seal, ensure that engine does not in use occur Leakage, so will guarantee the correctness that Rear oil seal assembles.Rear oil seal, originally during assembling, flatness and the degree of depth can only armrest senses, compress with frock is manual, then measure by dial gauge, first reference planes will be found when measurement, and this is all by operating personnel's manual confirmation, is certain to produce larger error like this, during use simple hand frock, operating personnel need to compress, measure, just need dismantle if defective, so very time-consuming, have a strong impact on operating efficiency, and the oil sealing of dismantling can not reuse, adds cost to a great extent.Engine Rear oil seal erecting tools utilizes the guiding of the screwing force of bolt and bolt (on bent axle major part equally distributed three screws), produce a Rear oil seal erecting tools be fixed on bent axle major part, prevent Rear oil seal mounting plane degree poor, for ensureing the quality of product and the uniformity of state.Therefore in the urgent need to designing and producing simple and reliable a kind of engine Rear oil seal installation method installation method and instrument, meeting Production requirement, improving the quality of products, reduce labour intensity.
Summary of the invention
The technical problems to be solved in the utility model is the defect overcoming prior art, and providing a kind of convenient, fast, safety, labour-saving engine Rear oil seal erecting tools can guarantee the accuracy that Rear oil seal is installed.
Technical solution of the present utility model is such, a kind of engine Rear oil seal, comprise locking nut, pressing sleeve, fairlead, screw, fishbolt, press mounting bolt, soket head cap screw, single thrust bearing, Rear oil seal, bent axle, it is characterized in that, between bent axle (10) and pressing sleeve (2), Rear oil seal (9) is installed, pressing sleeve (2) inner chamber installs fairlead (3), fairlead (3) inner chamber front end is provided with single thrust bearing (8), soket head cap screw (7), locking nut (1), there is installation fishbolt (5) on pressing sleeve (2) ring limit, fairlead (3) central lumen has installation press mounting bolt (6).
Fishbolt (5) is guide blot.
There is hex surface press mounting bolt (6) termination.
The instrument that the utility model has the advantages that is light and handy, easy to use, also reaches the accuracy of engine Rear oil seal when improving assembling simultaneously.

Detailed description of the invention
Below in conjunction with accompanying drawing, operation principle of the present utility model is described in detail.
Embodiment 1, with reference to drawings and Examples 1, single thrust bearing (8) selects (GB/T301) soket head cap screw (7) to adopt (GB/T70.1), and the termination section of fishbolt (5) protrudes the outer face of pressing sleeve (2) outward and termination section has screw thread, and this is threaded and tightens up bent axle (10).Press mounting bolt (6) axle head is installed single thrust bearing (8) and is pasted sealing gasket outward, and have soket head cap screw (7), locking nut (1) tightens.Rear oil seal (9) is installed between bent axle (10) and pressing sleeve (2), pressing sleeve (2) inner chamber installs fairlead (3), fairlead (3) inner chamber front end is provided with single thrust bearing (8), soket head cap screw (7), locking nut (1), fishbolt (5) is installed on pressing sleeve (2) ring limit, and fairlead (3) inner chamber installs press mounting bolt (6).Fishbolt (5) is guide blot.There is hex surface press mounting bolt (6) termination, and pneumatic wrench tightens press mounting bolt (6).Rear oil seal (9) is stuck in pressing sleeve (2).Bent axle (10) major part aimed at by fairlead (3).Fishbolt (5) is screwed into the screw of bent axle (10) major part.Have screw (4) to connect between pressing sleeve (2), fairlead (3) to tighten up.
Embodiment 2, during use, oil sealing is stuck on the pressing sleeve (2) of engine Rear oil seal erecting tools, bent axle major part aimed at by fairlead (3), 3 fishbolts (5) are screwed into the screw on bent axle major part, utilize the screwing force of fishbolt (5), fairlead and bent axle major part are compressed and fits, now fairlead can not rotate, such Rear oil seal erecting tools is just fixed on bent axle major part, rotate press mounting bolt to can not rotating, now oil sealing is depressed into correct position, finally fishbolt (5) is unscrewed and exit, twist off fishbolt (5), take out engine Rear oil seal erecting tools, namely the matching requirements (Figure 10) of engine Rear oil seal are completed.
The utility model engine Rear oil seal erecting tools principle: according to the screwing force and the guiding that utilize bolt, press mounting bolt utilizes the urgent frock that makes of pneumatic impact spanner to be accurately positioned on bent axle major part, fishbolt utilizes that pneumatic impact spanner is urgent makes that oil sealing is stable is pressed onto suitable installation site, and now the oil sealing degree of depth meets installation requirement.The utility model engine Rear oil seal and its instrument of installation method light and handy, easy to use, also reach the accuracy of engine Rear oil seal when improving assembling simultaneously.
