Abstract
The utility model discloses a kind of bulldozer engine loosing-proof devices, including cylinder body, bell housing, the cylinder body is tentatively connected on bell housing, the bell housing is equipped with 9 fixing bolt wire holes, it is bumped into guide respectively in the fixing bolt wire hole, bolt is embedded in guide and is fitted close fixing bolt wire hole, the bell housing lower end is equipped with the holes A and the holes B, and positioning pin is respectively embedded into the holes A and the holes B；The loosening for being a little to solve the problems, such as between cylinder body and bell housing of the utility model, while extending the service life of the accessories such as cylinder body, bell housing, certain economic loss is avoided, to reduce economic cost.
Description
Technical field
The utility model is related to technical field of engines, more particularly to a kind of bulldozer engine loosing-proof device.
Background technology
Cylinder body and bell housing are one of main parts sizes of engine, and primarily as the shell of flywheel, connection is started
Machine cylinder body and gearbox etc., but engine cylinder body is easy to loosen when connecting bell housing so that the hole of bell housing becomes
Greatly, to allow bolt to be easy to fall off, the positioning pin especially on bell housing loses the effect of positioning stablity, thus can be started
The accessories such as machine cylinder body, bell housing and power output device bring direct damage, generate certain extra cost.
Utility model content
The purpose of this utility model, which is to provide, a kind of to be reduced cost, prolongs the service life, reduces between cylinder body and bell housing
A kind of bulldozer engine loosing-proof device loosened.
What the purpose of this utility model was realized in：A kind of bulldozer engine loosing-proof device, including cylinder body, flywheel
Shell, the cylinder body are tentatively connected on bell housing, and the bell housing is equipped with 9 fixing bolt wire holes, the fixing bolt silk
Guide is bumped into hole respectively, will bolt be embedded in guide in be fitted close fixing bolt wire hole, the bell housing lower end be equipped with the holes A and
The holes B are respectively embedded into positioning pin in the holes A and the holes B.
As the further preferred scheme of the utility model, a diameter of 20 millimeters of the fixing bolt wire hole.
As the further preferred scheme of the utility model, the guide uses 45# carbon steel, and thickness is 2 millimeters, interior
Diameter is 16 millimeters, outer diameter is 20 millimeters.
As the further preferred scheme of the utility model, the holes A and the holes B are symmetrical, and wherein the holes A aperture is 12.5
Millimeter, depth is 95 millimeters；The holes B aperture is 12.5 millimeters, and depth is 135 millimeters.
As the further preferred scheme of the utility model, it is in 0.8*45 ° that the positioning pin, which uses straight pin, chamfering,
Its specification can be used 95*13 millimeters and 135*13 millimeters.
As the further preferred scheme of the utility model, the height of the guide is the thickness one of 90 millimeters and bell housing
It causes.
The beneficial effects of the utility model are compared with prior art：Due to passing through the fixing bolt of bell housing in the market
Wire hole diameter is 17.4 millimeters, and the utility model is used using the central point of fixing bolt wire hole as basic point, is expanded as 20 millis
Rice, guide easy to process, while but also the gap between fixing bolt and fixing bolt wire hole is reduced, to reduce fixed spiral shell
The hidden danger that bolt falls off；Since positioning pin diameter is only 10 millimeters in the market, intensity and contact surface are smaller, therefore it is diameter to be expanded
It is 95 millimeters and the hole 12.5 millimeters a diameter of, depth is 135 millimeters, the i.e. holes A and the holes B for 12.5 millimeters, depth, then distinguishes
The positioning pin of 95 × 13 millimeters and 135 × 13 millimeters of processing, chamfering is 0.8 × 45 ° and they is embedded in hole, and then preferably will
It is connected between bell housing and cylinder body.
Description of the drawings
Fig. 1 is utility model structural schematic diagram.
Fig. 2 is utility model assembling schematic diagram.
Wherein, 1 cylinder body, 2 bell housings, 3 fixing bolt wire holes, the holes 4A, the holes 5B.
