4results about How to "Drive directly" patented technology

This application relates to the field of transmission control technology, and more particularly to an automatic shifting mechanism for vehicles. The automatic shifting mechanism includes a housing assembly (1), a motor (2), a hollow shaft (3), a nut sleeve (41), and a lead screw (42). Since the hollow shaft (3) is fixedly connected to the inner rotor of the motor (2), the hollow shaft (3) rotates synchronously with the inner rotor of the motor (2), and the nut sleeve (41) also rotates along with the hollow shaft (3). Simultaneously, because the end of the lead screw (42) is limited by the housing assembly (1) and cannot rotate, the lead screw (42) moves axially along the thread of the rotating nut sleeve (41), achieving linear motion of extension or retraction. By coaxially integrating the motor (2) and the lead screw (42) mechanism, the structure is very compact, the transmission chain is short, and the efficiency is high, achieving precise electronically controlled linear drive.

The invention discloses an anthropomorphic joint system of multi-dimensional magnetic suspension and electromagnetic gradual change force control and telescopic bionic muscle tendons and a control method, and belongs to the technical field of bionic robots, intelligent mechanical joints and electromagnetic control. The technical problems that an existing robot joint is serious in mechanical abrasion, stiff in movement, poor in stability, low in bionic degree, rough in force control effect and the like are solved. The system comprises a multi-dimensional magnetic suspension normal-state stable supporting module, a telescopic bionic muscle tendon module, a multi-unit vector electromagnetic cooperative driving module, an electromagnetic polarity smooth switching and bidirectional driving module and a bionic self-learning gradual change type force control module. Non-contact and wear-free operation of the joints is achieved through multi-dimensional magnetic suspension, anthropomorphic movement is achieved through telescopic bionic muscle tendons, and precise and flexible control is achieved through vector electromagnetism and gradual change force control. The invention has the advantages of zero wear, long service life, multidimensional stability, high humanoid degree, soft force control, simple structure and the like, and is suitable for the fields of humanoid robots, medical rehabilitation robots, intelligent prostheses, humanoid interaction equipment and the like.

This utility model discloses a pruning machine blade assembly, including a first blade (1), a second blade (2), a pressure strip (3), a partition strip (4), a drive gear (5), and multiple sets of fixing bolts and nuts. The drive gear (5) has an integrally structured central block (21), and the central block (21) has at least one positioning rod (14) that passes through the first disc (11) and the second disc (13). Rotating the drive gear (5) causes the first blade (1) and the second blade (2) to reciprocate linearly. This pruning machine blade assembly uses an integrally structured drive gear, which drives the tail ends of the two blades with the body of the drive gear, while fixing the positioning rod of the drive gear to the central block of the drive gear, thus improving the connection strength, reducing the probability of loosening, and eliminating the risk of slippage.

The utility model discloses a kind of mixers for washing vanadium tank, including main stirring shaft and vice stirring shaft, the bottom of the outside of main stirring shaft is fixed with upper extension boss, the top of the outside of vice stirring shaft extends with lower extension boss, the top of lower extension boss is fixed with connecting rod, the middle part of connecting rod is threadedly connected with lower locking nut, the top of connecting rod is threadedly connected with upper locking nut, the surface of main stirring shaft is equipped with locking cylinder. A kind of mixer for washing vanadium tank provided by the utility model, by the connecting mechanism of upper extension boss, lower extension boss, connecting rod, upper / lower locking nut and locking cylinder being sleeved on main stirring shaft, main stirring shaft and vice stirring shaft are detachably connected together. When only the bottom area of tank or vice stirring shaft part needs to be overhauled, the whole mixer does not need to be completely lifted out of tank.
