Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to an engine working machine.

(Prior Art) In engine working machines such as motor generators, the engine and the working machine are arranged above and below a support plate in order to reduce the installation space.

(Problem that the invention aims to solve) However, in operating conditions, the engine and the work machine become vibrating bodies, so it is necessary to mount the engine and work machine above and below the support plate in order to make them the same vibration system. Although this is possible, if the engine and working machine are supported by one flat plate, securing the rigidity of the support plate becomes a problem. For this reason, if the support plate is made thick, the weight will increase.

Also, when the vibration systems are configured the same as this,
The mounting member for the tension adjustment roller on the transmission member such as a belt of the transmission device that connects the engine output shaft and the work equipment input shaft, and the operation plate on which the operation control lever faces are configured separately from the vibration system. This is not preferable and also increases the number of parts.

Furthermore, if the support plate is directly fixed to the outer frame of the aircraft body, the outer frame will also constitute a vibration system, which must be avoided.

This idea was created in view of the above problems.
The purpose of this is to configure the engine, work equipment, and operation system into the same vibration system, to ensure the rigidity of the support plate that supports the vibration system while reducing the weight, and to utilize the support plate. To provide an engine working machine which can rationally support a tension adjusting roller of a transmission member and also serve as an operation plate for facing a driving operation lever, and which makes it difficult to transmit vibrations to an outer frame.
