Description

[Detailed description of the invention] [Industrial application field] This invention allows the output shaft of the engine to be directly attached and detached via a key to a pinion that is integrally connected to an actuator such as a sprayer or pump. Tonashi,
This invention relates to an engine-directly coupled actuator that reduces the number of parts for transmitting power from the engine to the actuator, reduces the size of the reducer, and facilitates the maintenance and management of the actuator and engine. It is.

[Prior Art] Conventionally, when an engine drives an actuator such as a sprayer or a pump, it is common to use a belt or chain as a power transmission means, but safety management and equipment during work are difficult. There is a tendency to interpose a reducer between the engine and the actuator from the viewpoint of downsizing the engine and the actuator, and in the case of well-known reducers, (i) a sprayer (or pump) and a reducer, or (ii) The assembly of the engine and reducer is further attached to the engine in (i), and the sprayer (or pump) in (ii).
Since it is impossible to attach the engine to the engine, it is necessary to assemble the individual parts one by one, with the engine as the main consideration.

[The problem that the idea aims to solve]

While it takes a great deal of time and effort to assemble or remove the parts that serve as the drive means by the engine of the actuator mentioned above, there are many necessary parts, and moreover, the pinion in the reducer is supported by a bearing.
The shape of the reducer housing itself has become larger, which inevitably leads to larger and heavier equipment such as sprayers, pumps, and engines that must be assembled into the reducer. This method has problems such as a sense of complication.

This idea was devised by focusing on the problems mentioned above, and its purpose was to reduce the number of parts for transmitting power from the engine to the actuator, and to improve the connection between the actuator and the engine. The purpose of this invention is to provide an engine-directly connected operating device that is easy to attach and detach.

[Means to solve the problem]

In order to achieve the above-mentioned object, the engine-directly coupled actuator in this invention includes an actuator, a gear fitted to the input shaft of the actuator, and a side edge of the actuator capable of accommodating the gear. A housing is integrally connected on one side, and the output shaft of the prime mover can be fitted on the other side, and is detachable from the prime mover. a pinion that can be integrally coupled and meshes with the gear, and in an annular recess on the outer periphery of the pinion,
It is made by inserting and fixing the tip of a bolt that fits from the outside of the side edge of the case.

〔Example〕

Examples will be described below with reference to the drawings.

Actuator A, such as a sprayer or reciprocating pump
An input shaft 2 (here, the crank) is rotatably supported by a bearing 1 set on one side (here, on the right side), and its tip is connected to the inside of a casing 3 in which lubricating oil is stored inside the reducer R. A gear 5 is fixed to the outer periphery of this protruding part via a key 4, and a stud bolt 6 is screwed and fixed to the tip of the input shaft 2 via a washer W that abuts the gear 5. 5 input shaft 2
They are prevented from leaving. However, the gear 5
A keyway d is carved along the longitudinal direction of the inner circumferential edge of the cylindrical pinion 7 that engages with the cylindrical pinion 7, while an annular recess V provided at a suitable location on the outer circumferential edge of the pinion 7 is placed on the outer side edge of the housing 3. By inserting and fixing the tip of the bolt 8 which can be inserted further, it is possible to prevent the pinion 7 from moving inadvertently along the longitudinal direction. Engine E
A key K attached to the outer periphery of the output shaft 9 that can protrude outside is removably exposed to the key groove d.
0, the power of the engine E is transmitted to the input shaft 2 via the pinion 7 and the gear 5, and the actuator A can perform a desired operation such as spraying or discharging a chemical solution. 11 in the figure is an oil seal,
n is a female thread, and P is a plug.

[Action/Effect]

Since this device has the above-mentioned configuration, when connecting the engine E to the actuator A, the key K is inserted into the key groove d on the inner peripheral edge of the pinion 7 along with the output shaft 9 of the engine E, and the bolt 10 is inserted. The housing 3 of the reducer R and the engine E are integrally connected by screwing into and tightening the female thread n of the housing of the engine E. When engine E is started, power is transferred to output shaft 9, pinion 7,
Via the gear 5 and the input shaft 2, it drives an actuator A, such as a sprayer or a pump.

Furthermore, when removing the engine E from the actuator A, the bolt 10 can be removed from the female thread n and the output shaft 9 can be removed from the pinion 7, making it extremely easy to separate, and there is no need to take the trouble to drain the lubricating oil inside the housing 3. do not have.

Furthermore, when connecting engines E with various specifications such as the outer diameter of the output shaft 9 and the width of the key K to the actuator A, it is sufficient to prepare a pinion 7 corresponding to the output shaft 9 and the key K. There is no need to prepare a large number of various parts required for power transmission in the past, and management costs can be significantly reduced.Therefore, it can be handled extremely easily by any person. Since the tip of the bolt 8 that can be inserted from the top is inserted and fixed, it is possible to prevent the pinion 7 from moving in the longitudinal direction unexpectedly as described above, and to maintain a stable assembly state with the gear 5 and the key K at all times. Since it can be held and does not complicate the structure itself, it can be produced robustly and inexpensively, and it can be widely supplied to general users by suppressing the increase in overall size and weight. It has practical benefits such as
