Abstract
The utility model discloses a one-way clutch which consists of a planetary gear retarding mechanism, a driving casing, an internal spiral splined sleeve, a shifting fork block and a telescopic driving shaft, wherein an external spiral spline is arranged at one end of the telescopic driving shaft; a middle shaft of the driving casing is hollow; an internal spiral spline is arranged in the middle shaft and is matched with the external spiral spline on the telescopic driving shaft. The one-way clutch is characterized in that a cylindrical pin plate of a planetary gear on the planetary gear retarding mechanism is fixedly arranged on one end face of a driving sheath. According to the one-way clutch disclosed by the utility model, the cylindrical pin plate and the driving casing are separated and then are respectively and independently processed, so that the processing precision of the cylindrical pin plate of the planetary gear retarding mechanism can be effectively improved and work conditions of the planetary gear retarding mechanism are remarkably improved.
Description
Technical field
The utility model belongs to the starter motor field of motor, refers more particularly to a kind of overrunning clutch.
Background technique
In the start-up course of the starter motor of high power engine, the powerful starting electrical machinery that matches need to be arranged, in order to reduce the volume of starting electrical machinery, often select high-speed electric expreess locomotive again through slowing down, increase the motor output torque, to reach the purpose of ato unit.The retarding method of commonly using in the market, utilize planetary gear speed-reduction to realize, in the structure of one-way element, rear end is often planetary gear reducing mechanism, the planetary gear reducing mechanism front end connects the cover of driver of overrunning clutch, by cover of driver, drive telescopic propeller shaft again, the power of starter motor is added on the flywheel of motor, realize starting.because the transmission of power of overrunning clutch is by the internal thread spline on cover of driver, with outer spiral spline on telescopic propeller shaft, coordinate and to realize, and while between spline, by spiral gear, coordinating, exist certain gap, when the flywheel of telescopic propeller shaft and motor is realized gear engagement, the flywheel of motor must can produce a radial force to telescopic propeller shaft, cause the fitting surface of the outer spiral spline on internal thread spline and telescopic propeller shaft to produce around to rotation, when serious, cause two keys locked and cause the telescopic propeller shaft playback that can not bounce back, finally cause overrunning clutch to damage in the start-up course of starter motor of high power engine, the powerful starting electrical machinery that matches need to be arranged, in order to reduce the volume of starting electrical machinery, often select high-speed electric expreess locomotive again through slowing down, increase the motor output torque, to reach the purpose of ato unit.The retarding method of commonly using in the market, utilize planetary gear speed-reduction to realize, in the structure of one-way element, rear end is often planetary gear reducing mechanism, the front end of planetary gear reducing mechanism connects the cover of driver of overrunning clutch, by cover of driver, drive telescopic propeller shaft again, the power of starter motor is added on the flywheel of motor, realize starting.because the transmission of power of overrunning clutch is by the internal thread spline on cover of driver, with outer spiral spline on telescopic propeller shaft, coordinate and to realize, and while between spline, by spiral gear, coordinating, exist certain gap, when the flywheel of telescopic propeller shaft and motor is realized gear engagement, the flywheel of motor must produce a radial force to telescopic propeller shaft, cause the fitting surface of the outer spiral spline on internal thread spline and telescopic propeller shaft to produce around to rotation, when serious, cause two keys locked and cause the telescopic propeller shaft playback that can not bounce back, finally cause overrunning clutch to damage.In order to improve two, spend the strong mode that coordinates, the planetary pinion straight pin on planetary gear reducing mechanism directly can be installed on and drive outer putting, make to drive overcoat and planetary gear reducing mechanism forms stable fit system.But in planetary gear reducing mechanism, the positional accuracy of planetary pinion straight pin is directly connected to the operating mode of planetary gear reducing mechanism, and bigger error can directly cause the consequence that mechanical wear is excessive and noise is excessive.
Summary of the invention
The purpose of this utility model is to provide a kind of positional accuracy machining accuracy that can effectively improve the planetary pinion straight pin, reduces between internal thread spline and the outer spiral spline on telescopic propeller shaft on cover of driver around the overrunning clutch to rotation.
The utility model is realized by following manner: a kind of overrunning clutch, by planetary gear reducing mechanism, cover of driver, internal thread spline cover, cutting ferrule, fork seat, telescopic propeller shaft, formed, wherein an end of telescopic propeller shaft is established outer spiral spline, the axis of cover of driver is hollow, inside be provided with internal thread spline, with the outer spiral spline on telescopic propeller shaft, coordinate, it is characterized in that: the planetary pinion cylinder pin plate on described planetary gear reducing mechanism is fixed on an end face that drives overcoat.
The surface of contact of described planetary pinion cylinder pin plate and cover of driver is established one convex is installed, and its circumferential shapes is supporting with the interior loop-shaped of driving overcoat.
Due to the utility model by the cylinder pin plate with after cover of driver separates, both distinguish independent processing, can effectively improve the machining accuracy of the cylinder pin plate of planetary gear reducing mechanism, and the operating mode of planetary gear reducing mechanism is significantly improved.Realized that cover of driver and planetary gear reducing mechanism are integrated into one effectively, made the cooperation of inside and outside helical spline stable, but also made the structure display of overrunning clutch obtain more compact, reasonable.
The accompanying drawing explanation
Fig. 1 is the structural representation of overrunning clutch;
Fig. 2 is the straight pin plate structure front view of planetary gear reducing mechanism;
Fig. 3 is the straight pin plate structure left view of planetary gear reducing mechanism.
Embodiment
As shown in Figure 1: an end of telescopic propeller shaft 7 is established outer spiral spline, and the other end, for the actuation gear of flywheel driven rotation is installed, is installed fork seat 6 on telescopic propeller shaft 7.
