The application provides a blade arc grinding process and belongs to the technical field of blade processing. The blade arc grinding process comprises the following steps: fixing the bottom of the blade through a lower fixing mechanism to facilitate the placement of the blade; fixing the upper part of the blade through an upper fixing mechanism to facilitate the grinding of the blade; installing the grinding wheel body through an installation mechanism to facilitate the replacement of the grinding wheel body; moving the grinding wheel body through a driving mechanism to facilitate the grinding of the blade by the grinding wheel body; and placing the blade in the fixed groove through the lower fixing mechanism, and the elasticity of the two return springs in each automatic clamping assembly enables the clamping block to automatically fix the bottom of the blade, so that the blade is placed more stably.

The application belongs to the technical field of amphibious special vehicle, and relates to a steering control method of a single front axle wheel and track composite walking system of a special vehicle. A sensor measures and obtains relevant parameters, and the relevant parameters are determined when the special vehicle is designed; a control component calculates (1) a steering inner track driving force F ti (2) a steering outer track driving force F to ; and the control component controls a driving motor to output a driving force with a value according to the calculated steering inner track driving force F ti and the steering outer track driving force F to . The steering control method of the single front axle wheel and track composite walking system of the special vehicle can be reliably applied to the special vehicle with the single front axle and track composite walking system, and can control the size of the track driving force in real time during driving steering, so that the wheel and track steering torques are consistent according to the bearing proportion, the wheel drags the track or the track drags the wheel is avoided, the additional load of the structure is reduced, the wheel and track are minimized in wear, and the performance is improved.

According to an embodiment, a refrigerator is disclosed. The refrigerator includes a first door opening and closing a storage compartment of a cabinet, and a second door rotatably coupled to the first door with respect to the first door by a second hinge. The second hinge includes a locking hook installed to be reciprocally moved along the hinge coupling portion by the operation of the door opening and closing device, and engaged with the locking protrusion to be locked or unlocked when the second door is opened and closed. Thus, the locking hook can be automatically locked or unlocked with respect to the locking protrusion of the first door by the operation of the door opening and closing device.

This invention relates to a face spline structure for transmitting driving force to a vehicle, and a power transmission device including a drive shaft and a hub assembly interconnected by the face spline structure. The face spline structure includes a first face spline and a second face spline that mesh with each other to transmit rotational power. A first gap between the peak of the first face spline and the root of the second face spline meshing therewith, and a second gap between the peak of the second face spline and the root of the first face spline meshing therewith, are each in the range of 0.2 mm to 0.7 mm.
