Description
Technical field
This utility model relates to the structure of marine diesel, is specifically related to a kind of door closure device for installing diesel engine angular encoder, belongs to Diesel Engine Technique Field.
Background technology
Angular encoder is the measurement apparatus that diesel engine is conventional, is mainly used to measure the angular displacement that bent axle rotates, and is also commonly used for the test such as torsional vibration measurement, combustion analysis or other relevant devices needing to measure angular displacement.End that in diesel engine, angular encoder is generally mounted to crankshaft free-end or the end of dummy shaft being connected with bent axle, crankshaft center is had concentricity requirement by its installation.
In actual applications, due to engine arrangement reason, or because test demand installs angular encoder additional temporarily, the situation that the crankshaft free-end portion free end cap outerplanar of distance is distant often occurs.Setting angle encoder in this case, it is necessary to install a dummy shaft in crankshaft end and stretch out end cap plane, and angular encoder is arranged on dummy shaft end face, and fixing by the support being arranged on outside end cap.Owing to crankshaft end is distant from end cap outerplanar, dummy shaft is also accomplished by long, but this can cause that dummy shaft bending affects the concentricity that angular encoder is installed, therefore must take into increase bearings or other structures to ensure the concentricity that angular encoder is installed, but which results in structure complexity, needs number of parts many, relatively difficult problem is installed.
Utility model content
The purpose of this utility model is in that the deficiency overcoming prior art to exist, it is provided that a kind of door closure device for installing diesel engine angular encoder, to simplify mounting structure, reduces installation difficulty.
In order to achieve the above object, the technical scheme that this utility model provides is as follows:
A kind of door closure device for installing diesel engine angular encoder, it is installed on the free end of crankshaft of diesel engine, it is characterized in that, described door closure device is barrel-shaped, the end cap place of diesel engine it is connected in the way of locality indent, this door closure device includes staving, one end that this staving is uncovered is provided with for installing fixing flange, central authorities bottom described staving are provided with central through hole, it is fixedly connected with an annular portion in close proximity to the back side of the drum head of this central through hole, the annular distance of this annular portion is coaxial with described central through hole, described annular portion is provided with the screwed hole for connecting vexed plate, the medial surface of this vexed plate and described annular portion forms the oil seal groove disposing oil sealing in described central through hole, the bottom of described staving is provided with the screw of setting angle encoder.
Further, the outside of described staving is welded with reinforcement gusset.
Further, described door closure device adopts Plate Welding to form.
Further, described flange is circumferentially provided with installing hole.
Compared with prior art, the beneficial effects of the utility model are:
(1) adopt concave shaped bucket body structure, it is to avoid dummy shaft length is long and the angular encoder that causes installs the defect of concentricity difference.
(2) oil sealing can be disposed in the oil seal groove formed, it is therefore prevented that lubrication leakage.
(3) vexed plate is arranged on outside central through hole, it is possible to prevent oil sealing from coming off.
(4) simple in construction, easy for installation.

Detailed description of the invention
Below in conjunction with accompanying drawing and concrete example, the utility model is described in further detail, but can not limit protection domain of the present utility model with this.
Incorporated by reference to consulting Fig. 1 and Fig. 2, it is shown that the door closure device for installing diesel engine angular encoder adopts Plate Welding to form, and in barrel-shaped, is connected to the end cap place of diesel engine in the way of locality indent.Described door closure device includes staving 1, and one end that this staving 1 is uncovered is provided with flange 3, this flange 3 is circumferentially provided with installing hole 31 (bolt hole and pin-and-hole), for fixing and positioning of integral door lid arrangement.Central authorities bottom described staving 1 are provided with central through hole 2, in order to the dummy shaft being connected on crankshaft free-end passes, and bearing support structure that need not be extra.An annular portion 4 it is fixedly connected with in close proximity to the back side of the drum head of this central through hole 2, the annular distance of this annular portion 4 is coaxial with described central through hole 2, described annular portion 4 is provided with the medial surface of the screwed hole 6 for connecting vexed plate, this vexed plate and described annular portion 4 and forms the oil seal groove 5 disposing oil sealing in described central through hole 2.The bottom of described staving 1 is provided with boss 7, and this boss 7 place is provided with the screw 8 of setting angle encoder.The outside of described staving 1 is welded with four pieces and strengthens gusset 9, to improve the rigidity of door closure device, it is prevented that deformation.
Fig. 3 and Fig. 4 is scheme of installation of the present utility model, and described door closure device 01 is installed on the crankshaft free-end place of diesel engine 02, and this crankshaft free-end is connected to dummy shaft 03.Described flange 3 is installed on the end cap place of diesel engine 02, and owing to described door closure device is connected with diesel engine 02 end cap in the way of locality indent, the length therefore avoiding dummy shaft 03 is long.Oil sealing 04 is installed in the oil seal groove 5 between dummy shaft 03 and central through hole 2, it is therefore prevented that lubrication leakage.Vexed plate 05 is arranged on the outside of central through hole 2, it is prevented that oil sealing 04 comes off.Angular encoder 06 is installed on the end of dummy shaft 03, and fixes its support by screw 8.
This utility model simple in construction, easy for installation.
