The embodiment of the utility model discloses an unmanned aerial vehicle drive circuit, which comprises a flight control system, a driver group, a temperature sensor group and a motor group, and is characterized in that the flight control system is connected with the motor group through the driver group, the output ends of motors in the motor group are connected in parallel through output shafts, and the temperature sensor group is connected with the temperature sensor group. The temperature sensor group is arranged between the driver group and the motor group, each driver in the driver group performs data interaction through a communication port, and each motor in the motor group is in one-to-one correspondence with each driver in the driver group. Each driver in the driver group realizes data sharing, so that the control output is synchronous, the current sharing effect of motor winding driving is realized, the total power is ensured to be maximized, and meanwhile, the rotating speed control is also ensured to be more accurate.

This invention relates to the field of food processing equipment technology, and discloses a food processing machine with stable operation, including a mixing cup and a main unit equipped with a motor and a reduction mechanism. The reduction mechanism includes a fixed gear ring, a double gear, a moving gear ring, and a planetary carrier that cooperate with each other. The double gear includes a gear with a shaft hole and a gear shaft passing through the shaft hole. The gear shaft and the motor shaft are arranged side by side, and the motor shaft drives the gear and gear shaft to rotate synchronously. The gear includes an upper gear that meshes with the fixed gear ring and a lower gear that meshes with the moving gear ring. The shaft hole wall is provided with a wear-resistant part, which surrounds the gear shaft to limit the radial movement of the gear shaft. The outer surface of the wear-resistant part is fixedly connected to the shaft hole wall, and a heat dissipation gap is provided between the inner surface of the wear-resistant part and the gear shaft. The axial height h2 of the wear-resistant part and the shaft hole wall height h1 satisfy 1 / 2h1<h2≤h1-2mm. This avoids direct contact between the gear shaft and the shaft hole, provides good wear resistance to the shaft hole, ensures good alignment between the gear and the rotating shaft, and ensures stable operation.

The invention relates to an axle, in particular for a utility vehicle, comprising a first wheel end (2) and a second wheel end (3), which are arranged or can be arranged opposite one another on the axle (1) in a rotational manner, a recuperation device (13), which is connected or can be connected to the first wheel end (2) and is designed to recuperate the rotational energy of the first wheel end (2), a brake device (5), which is designed to retard the second wheel end (3), and a control unit (11), which is designed to determine information about the retardation of the first wheel end (2), which is caused by the recuperation, and / or the retardation of the second wheel end (3), and to control the brake device (5) and / or the recuperation device (13) such that the retardation of the first wheel end (3) and the retardation of the second wheel end (3) match one another. A further aspect of the invention relates to a method for compensating for the retardation of a first wheel end (2) of an axle (1), in particular for a utility vehicle, which is caused by a recuperation process.

This utility model discloses a welded pipe turning mechanism, relating to the technical field of welded pipe production equipment. It includes a processing table with a power drive mechanism at its upper end and an adjustable turning mechanism above the processing table. This utility model, through the cooperation of a telescopic rod and a movable plate, allows for flexible adjustment of the distance between two sets of turning rollers, adapting to the turning requirements of welded pipes of different specifications. Secondly, two servo motors drive the two sets of turning rollers respectively, providing sufficient and stable power. Compared to a single drive method, this ensures uniform torque during the turning process, preventing turning jams or asynchrony even when handling large-diameter, heavy welded pipes. Simultaneously, the anti-slip rubber sleeves and annular grooves on the turning rollers significantly enhance friction with the welded pipe, preventing slippage during turning and ensuring stable and reliable turning action, effectively improving production efficiency and product quality.
