4results about How to "Reduce dynamic load" patented technology

The utility model belongs to angle adjusting hinge technical field especially a kind of self-locking ratchet angle adjusting hinge, including support seat and the adjusting seat of rotation connection with support seat, the upper surface of support seat is provided with self-locking mechanism, the self-locking mechanism includes spring and ball rod, the spring is driven by its elastic deformation and resets ball rod, by setting fixed mechanism, positioning and fixing are carried out to support seat, user when installing adjusting hinge, first, it is initially fixed on target object by back glue, the adhesion of back glue can fill up the tiny gap between support seat, adjusting seat and target object, then further fixed using bolt, form double fixed mechanism, the initial fixation of back glue can reduce installation difficulty and time, and its adhesive layer can absorb vibration and impact force, reduce the dynamic load that bolt bears, prolong the service life of overall structure.

The utility model relates to the technical field of construction vibration reduction, in particular to a vibration reduction and isolation guide assembly. The device moves up and down on the guide rail through the guide unit. The guide unit comprises a hollow shaft, a guide wheel, a first elastic washer, a first fixing ring, a second elastic washer, a second fixing ring and a bearing, a double vibration reduction and isolation structure is formed through sleeving connection of all the parts, vibration of a vibration source to a guide rail embedded in the guide wheel can be remarkably reduced, and therefore mechanical equipment is protected.

This utility model relates to a connecting rod balancing mechanism for a beam pumping unit, comprising a lower connecting rod joint, a crank pin bearing housing, a crank pin, a crank, a crank pin bearing cover, and a crank pin bearing. The lower connecting rod joint and the crank pin bearing housing are fixedly connected as an integral connecting rod-crank pin structure. The key feature is that a connecting rod balance box is connected to the lower connecting rod joint or the crank pin bearing housing, forming the connecting rod balancing structure of the beam pumping unit. The connecting rod balance box is connected to the lower connecting rod joint or the crank pin bearing housing via a flange or pin. This utility model achieves a new balancing method by setting a balance box at the lower end of the connecting rod or the crank pin bearing housing. The counterweight is set at the lower end of the connecting rod or the crank pin bearing housing, reducing the force on the crank pin and lowering the risk of crank pin breakage. It also avoids the drawback of large inertial loads in beam balancing.

This application provides a motorcycle including a frame, a running gear, body panels, and a power system. The frame includes a front support bracket, a rear support bracket, a center cross tube, and an engine mount. The engine mount is at least partially located behind the center cross tube and connected to the rear support bracket. The power system includes an engine assembly and a suspension assembly. The suspension assembly includes a suspension body, a first limiting arm, a second limiting arm, and a connecting arm. The connecting arm is located on one side of the suspension body. The first and second limiting arms are located on the side of the suspension body away from the connecting arm. The suspension body is rotatably connected to the engine mount. The connecting arm is rotatably connected to the engine assembly. When the engine assembly is connected to both the engine mount and the engine assembly via the suspension assembly, the center cross tube is located between the first and second limiting arms. This application provides a motorcycle with improved ride smoothness.
