Problems solved by technology
With this method, it is inconvenient to adjust the movable clearance and the consistency is poor, and when the nut insurance fails, there is a hidden danger of the rocker arm being stuck
At the same time, the installation shaft used needs to be specially made, and the existing bolt standard parts cannot be directly used; at the same time, due to the relative movement between the installation shaft and the rotating rocker arm, wear and tear will occur, and the repair and maintenance costs are high

The invention discloses a clearance adjusting bushing for a support and a rotating rocker arm, which comprises a bushing body, the bushing body includes a position-limiting projection for contacting the support, and a The connection section connected with the connecting hole in the arm is rotatably connected, and an oil storage tank communicated with the rotating rocker arm is provided on the side wall of the connection section; the limit protrusion in the bushing body is used to limit the The minimum gap between the seat and the rocker arm; the connecting section in the sleeve body is used to control the movable gap of the rocker arm. The gap adjusting bushing of the present invention can control the minimum gap between the support and the rotating rocker arm and the movable gap of the rotating rocker arm, has a simple structure, is convenient for maintenance, can effectively reduce maintenance costs, is safe and practical, and is suitable for popularization use.
Description
technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a gap-adjusting bushing used for a support and a rotating rocker arm. Background technique [0002] There are many forms of mechanical transmission, which can be mainly divided into two categories: one is the friction transmission that transmits power and motion by friction between parts, including belt transmission, rope transmission and friction wheel transmission. Friction transmission is easy to achieve stepless speed change, and most of them can adapt to transmission occasions with large shaft spacing. Overload slipping can also play a role in buffering and protecting the transmission device, but this kind of transmission generally cannot be used in high-power occasions, nor can it guarantee accuracy. transmission ratio. The second is the meshing transmission that relies on the meshing of the active part and the driven part or the meshing of the intermediate...
