The volute spiral spring starter comprises an energy storage mechanism, an energy storage control mechanism and a one-way clutch. The volute spiral spring starter is characterized in that two ends of a volute spiral spring (6) are not fixed on a casing and can rotate, one end of the volute spiral spring is a driving end, the other end of the volute spiral spring is a driven end, both an inner end and an outer end can serve as the driving end and can also serve as the driven end, the driving end rotates while the driven end is fixed when energy is stored, the driving end is fixed while the driven end rotates when the energy is released, and the rotation direction of the two ends is consistent with that of an engine and is generally clockwise. The starter is labor-saving in operation, high in reliability, low in noise and long in service life.
Description
Technical field
The utility model is a kind of spiral spring starter, is specially adapted to the usefulness of the diesel engine starting of microtilling machine, also can be used for the startup of other diesel engine.
Background technique
Present microtilling machine mainly still uses stay cord starter, needs enough power just can draw startup, not only operation effort, and boot disk and also easily damage of stay cord.Also a lot of patent disclosures have been arranged by the microtilling machine starter of coiled spring energy-storage, such as Chinese patent 201020522549.4 disclosed " a kind of starter of diesel engine ", its shortcoming is: the outer end of spiral spring is fixed on the casing, rotate the inner of spiral spring during energy storage, rotate the inner that when releasing energy also is spiral spring, just turn to difference, the energy storage locking device is located at the front end of storage transmission system, namely before the clutch driving link, clutch driving link in this example is exactly sliding sleeve, energetically axle and small gear locking of locking device during energy storage, the part of some transmission systems all is in free state such as clutch driving link and clutch Passive part in addition, there is the gap between the part of these free states, make energy discharge the strong impact of moment generation, damage easily parts, rate of fault is high, working life is short.The outer end of this spiral spring is fixed on the casing, its structures shape the energy storage locking device of starter can not be located at the end of transmission system, namely after the clutch Passive part, the clutch Passive part in this example is exactly clutch.
Summary of the invention
The purpose of this utility model provides a kind of spiral spring starter, and the spiral spring two ends of this starter are not fixed on the casing, and drive end rotates during energy storage, and Partner rotates when releasing energy, and sense of rotation is identical.The energy storage locking device is located at the end of transmission system, and namely after the clutch Passive part, the institute of just having eliminated during energy storage between the transmission system part is gapped, when releasing energy, just do not have impact, not only rapid operation, and reliability is high, low, the long service life of noise.
The technical solution of the utility model is as follows: the spiral spring starter is comprised of stored energy mechanism, energy storage control mechanism and overrunning clutch three parts.Stored energy mechanism as shown in Figure 1 and Figure 2, formed by starter housing (1), gearwheel (2), crank handle interface (3), small gear (4), spiral spring pin (5), spiral spring (6) and spiral spring axle (7), the outer end of spiral spring (6) is connected with spiral spring pin (5), and the inner of spiral spring (6) is connected with spiral spring axle (7).Energy storage control mechanism such as Fig. 4, shown in Figure 5 are comprised of ratchet (8), ratchet (9), and the other end of ratchet is ratchet handle.Overrunning clutch is comprised of clutch driving plate (11), clutch driven disc (10).It is characterized in that: the two ends of spiral spring (6) are not fixed on the casing, and two ends can be rotated, and wherein an end is drive end, the other end is Partner, inner and outer end can also can be used as Partner as drive end, and drive end rotation Partner is fixed during energy storage; Fixedly Partner rotation of drive end when releasing energy, the sense of rotation at the two ends all sense of rotation with motor is consistent, is generally clockwise direction.Because the two ends of spiral spring (6) are not fixed on the casing, the energy storage control mechanism can be located at the end of transmission system, namely after the driven disc of overrunning clutch.Ratchet in this example (9) consists of an integral body with clutch driven disc (10), and is rigidly connected with engine flywheel, also ratchet directly can be designed on the flywheel of motor.
During energy storage, rotate with spiral spring pin (5) outer end of spiral spring (6), the inner of spiral spring (6) and spiral spring axle (7) are fixing, rotate spiral spring (6) outer end, spring turns tighter and tighter, storage elasticity potential energy, the elastic force of spiral spring runs through whole transmission system, until blocked clutch driven disc (10), this has just eliminated the gap between whole transmission system part, when releasing energy, the outer end of spiral spring (6) maintains static, rotate the inner by spiral spring (6), drives diesel engine and start, and has realized the purpose of this utility model.
