Embodiment Construction

[0016] Such as figure 1 , 2 As shown, the ring gear body 1 of the existing powder metallurgy deceleration ring gear is provided with a deceleration tooth 2, and the ring gear body 1 is provided with a full ring flange edge 4, and the flange edge 4 is provided with a positioning rib 3, and the ring gear body 1 The thickness (wall thickness) is 4mm, and the thickness of the flange side 4 and the positioning rib 3 is 6.33mm.

[0017] Such as image 3 , 4 As shown, the deceleration ring gear of the present invention cancels the whole ring flange 4, the thickness of the ring gear body 1 is changed to 3.2mm, and there are four strip-shaped positioning ribs 3 evenly distributed outside the ring gear body 1, and the positioning ribs 3 protrude from the teeth. Circle the bottom of the body 1 . The thickness of the positioning rib 3 is 2.74 mm, and the width of the positioning rib 3 is increased to 9 mm to increase the positioning contact area.

[0018] In general, the outer diamet...

Abstract

The invention discloses a compact high-power speed reduction gear ring for a starting machine of a diesel vehicle. The compact high-power speed reduction gear ring comprises a gear ring body; speed reduction teeth are arranged in the gear ring body; strip-shaped positioning ribs are evenly distributed on the outer surface of the gear ring body; the positioning ribs stick out from the bottom part of the gear ring body. According to the speed reduction gear ring disclosed by the invention, on the basis that the mechanical strength is ensured, the wall thickness and the height of a product are optimized, and the size is reduced, so that the speed reduction gear ring is lightweight, and meanwhile, the cost is reduced.

Description

technical field [0001] The invention relates to a powder metallurgy deceleration ring gear, in particular to a compact high-power deceleration ring gear for a diesel vehicle starter. Background technique [0002] The advantages and disadvantages of diesel engines are well known: after the diesel engine is injected with fuel, it takes a certain amount of time to burn, so it is suitable for the fuel to be fully burned at a low speed to bring high torque, and in order to meet the working conditions of high pressure and high torque in the cylinder, the diesel engine The mechanical performance requirements of parts such as cylinders and piston connecting rods are higher than those of gasoline engines, so they are more bulky than gasoline engines. But it is also because of the characteristics of high compression ratio and low speed that diesel engines can better convert heat into kinetic energy, so diesel engines have better thermal efficiency, that is, better fuel consumption per...
