4results about How to "Improved meshing" patented technology

This utility model relates to the field of electric motor technology, specifically disclosing a rack guide structure, including a guide sleeve with a guide channel. The cross-sectional shape of the guide channel is non-circular or non-arc, and the guide wall of the guide channel includes at least one planar segment. The guide channel is used to cooperate with an anti-rotation part on the rack. The cross-sectional shape of the anti-rotation part is adapted to the shape of the guide channel, allowing the rack to reciprocate along the guide channel. A pump electric motor includes a motor body, a gear, and a rack. The motor body drives the gear to rotate, and the rack meshes with the gear, serving as the reciprocating drive source for the pump body. It also includes the aforementioned rack guide structure. The guide sleeve in the rack guide structure is fixedly installed on the housing of the motor body, and the anti-rotation part of the rack cooperates with the guide channel of the guide sleeve. This solution addresses the problem of easy wear caused by rack deflection or tilting in current rack-output motors.

The utility model relates to the technical field of center spindles, in particular to a four-axis vertical machining center spindle synchronizing mechanism which comprises a bottom plate, a stand column and a workbench are fixedly arranged on the bottom plate, a fixing frame is arranged on one side of the stand column in a sliding mode, a plurality of spindle boxes are arranged in the fixing frame in a sliding mode, and spindles are arranged in the spindle boxes in a rotating mode. The positions of the spindle boxes in the fixing frame are flexibly adjusted according to different machining requirements so as to adapt to machining of stamping die accessories of different types or sizes, each spindle is fixedly connected with a large gear, every two adjacent spindle boxes are communicated with each other, a small gear is arranged between every two adjacent spindle boxes in a sliding mode, and the large gear and the small gear are meshed with each other. The small gear is meshed with the two adjacent large gears, the small gear can adapt to position changes of the large gears on the two adjacent spindles through the springs arranged on the two sides of the connecting rod, and when the position of the spindle box is adjusted, it can be guaranteed that the small gear is in a good meshing state with the large gears on the two sides all the time under the elastic force action of the springs.

The invention relates to a novel slewing mechanism. The far end of a connecting flange is connected with a rotating ring, the near end of the connecting flange is connected with a rotating shaft, the top of the rotating shaft is perpendicular to a rotating connecting disc, the far end of the rotating connecting disc is locked with a stand column, a shaft sleeve is installed on the outer side of the rotating shaft, and the outer side of the shaft sleeve is tightly attached to a slewing stand column sleeve. The bottom of the rotary stand column sleeve is installed at the nearest end of the installation plate, the far end of the installation plate is connected with the rack, and the near end of the installation plate is connected with the fixing ring. The speed reducer gear and the slewing bearing both ensure the perpendicularity, the torque or the inclined stress point of the working arm during working acts on the slewing stand column sleeve and is sequentially transmitted to the mounting plate and the rack, the slewing bearing is only responsible for the rotating function in the working state, the phenomena that a gear ring or a ball is seriously abraded, teeth are broken, and only one end of each tooth is ground are avoided, and the service life of the slewing bearing is prolonged. And a perfect meshing state is kept, so that the excavating machinery rotates quickly and stably, the service life of equipment is prolonged, and the slewing bearing with a small size can be suitable for high-torque equipment.

The invention discloses a robot walking on an arc-shaped anti-falling guide rail of a power transmission line, and belongs to the technical field of power transmission line maintenance equipment. The robot comprises a frame, a driving wheel assembly and a plurality of groups of driven wheel assemblies. The driving wheel assembly is provided with a driving wheel body with drum-shaped wheel teeth, the driving wheel body is connected with a power source through a flexible transmission shaft, and self-adaptive floating relative to the vertical direction of the frame is achieved through a floating bearing and a floating connecting mechanism. The driven wheel assemblies are symmetrically distributed on the two sides of the anti-falling guide rail, each driven wheel assembly comprises a driven wheel body and a transverse self-adaption mechanism, and the driven wheel bodies elastically press the side face of the anti-falling guide rail. The technical problems that due to the fact that the robot is difficult to adapt to a single continuous composite arc-shaped bent anti-falling guide rail, meshing is poor, abnormal abrasion is caused, clamping stagnation is likely to happen, and the derailing risk is large are effectively solved, and the trafficability, operation stability and operation safety of the robot on a complex space path are remarkably improved.
