Abstract
The utility model discloses a central gear positioning mechanism used in the engines. The utility model includes a central pinion which is arranged in the central gear shaft of an engine. A central gearwheel arrangement sheath which spreads outwards is arranged on the wheel body of the central pinion. The central gearwheel is arranged in a concentric way on the central gearwheel arrangement sheath. A cylinder pinhole is arranged on the central gearwheel on the central pinion. The cylinder pinhole is perpendicular to the axes of the central gear. A cylinder bolt is arranged in the cylinder pinhole. A positioning groove with a width matching with the width of the cylinder bolt is arranged on the gear body of the pinion close to the central gearwheel. The positioning groove spreads to the joining face of the central gearwheel and the central pinion along the axe of the central gearwheel. The utility model ensures the right matching positions of the central gear components as well as an enough magnitude of interference when the central gearwheel is assembled with the central pinion. The utility model prolongs the lifespan of central gear and enhances the reliability of the engines.
Description
Technical field
The utility model relates to a kind of positioning device of motor, relates in particular to a kind of positioning device of motor intermediate gear assemblies.
Background technique
The motor intermediate gear comprises the intermediate speed pinion that is installed on the motor intermediate gear shaft, has outward extending gear installation sleeve broad in the middle on the wheel body of described intermediate speed pinion, described gear broad in the middle is fixedly set on the described gear installation sleeve broad in the middle, and gear broad in the middle and intermediate speed pinion must guarantee correct cooperation position when assembling.At present, gear broad in the middle and intermediate speed pinion enough magnitude of interference when when assembling is difficult to guarantee correct cooperation position and assembling simultaneously not only makes the working life of intermediate gear very short, and reduces the reliability of motor.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of can guarantee simultaneously correct cooperation position and when assembling enough magnitude of interference motor intermediate gear positioning devices.
For achieving the above object, the technical solution of the utility model is: motor intermediate gear positioning device, comprise the intermediate speed pinion that is installed on the motor intermediate gear shaft, has outward extending gear installation sleeve broad in the middle on the wheel body of described intermediate speed pinion, described gear broad in the middle is with being sleeved on the described gear installation sleeve broad in the middle surely, gear installation sleeve broad in the middle on the described intermediate speed pinion is provided with cylinder pin hole, described cylinder pin hole is perpendicular to the axis of intermediate gear, and in the described cylinder pin hole straight pin is installed; Described gear broad in the middle is provided with the locating slot that width cooperates with described straight pin near the wheel body of described intermediate speed pinion, and described locating slot extends to the junction plane of described gear broad in the middle and described intermediate speed pinion along the axis of gear broad in the middle; Described locating slot is a curve bath.
Owing to adopt technique scheme, motor intermediate gear positioning device, comprise the intermediate speed pinion that is installed on the motor intermediate gear shaft, has outward extending gear installation sleeve broad in the middle on the wheel body of described intermediate speed pinion, described gear broad in the middle is fixedly set on the described gear installation sleeve broad in the middle, gear installation sleeve broad in the middle on the described intermediate speed pinion is provided with cylinder pin hole, and described cylinder pin hole is perpendicular to the axis of intermediate gear, and in the described cylinder pin hole straight pin is installed; Described gear broad in the middle is provided with the locating slot that width cooperates with described straight pin near the wheel body of described intermediate speed pinion, and described locating slot extends to the junction plane of described gear broad in the middle and described intermediate speed pinion along the axis of gear broad in the middle; Can guarantee that intermediate gear assemblies has correct cooperation position, in the time of guaranteeing the assembling of gear broad in the middle and intermediate speed pinion again enough magnitude of interference be arranged, prolong the working life of intermediate gear, improve the reliability of motor.
Description of drawings
Accompanying drawing is the utility model embodiment's a structural representation.
Embodiment
Motor intermediate gear positioning device as shown in drawings, comprise the intermediate speed pinion 1 that is installed on the motor intermediate gear shaft, has outward extending gear installation sleeve 4 broad in the middle on the wheel body of described intermediate speed pinion 1, described gear broad in the middle 3 is fixedly set on the described gear installation sleeve 4 broad in the middle, gear installation sleeve 4 broad in the middle on the described intermediate speed pinion 1 is provided with cylinder pin hole, described cylinder pin hole is perpendicular to the axis of intermediate gear, and straight pin 2 is installed in the described cylinder pin hole; Described gear broad in the middle 3 is provided with the locating slot 5 that width cooperates with described straight pin 2 near the wheel body of described intermediate speed pinion 1, and described locating slot 5 extends to the junction plane of described gear broad in the middle 3 and described intermediate speed pinion 1 along the axis of gear 3 broad in the middle; Described locating slot 5 is a curve bath.Intermediate gear cooperates the location by the cylinder pin hole on the intermediate speed pinion 1, and 3 curve bath cooperates installation on straight pin 2 and the gear broad in the middle, can guarantee the correct cooperation position that intermediate gear assemblies has; Gear 3 broad in the middle only has the curve bath that cooperates with straight pin 2 in the end, can guarantee to have enough magnitude of interference so again with the hot charging of intermediate speed pinion 1, this intermediate gear cooperates position structure to guarantee motor intermediate gear assemblies location and assembling, prolong the working life of intermediate gear, improved the reliability of motor.
