Provided is a wheel-leg composite type four-leg robot. The wheel-leg composite four-leg robot is characterized by comprising an inner car frame, an outer car frame, a cushioning assembly, two pairs of upper leg parallel connection assemblies and four wheel type legs with identical structures. The inner car frame is arranged inside the outer car frame. The inner car frame is connected with the outer car frame through the cushioning assembly. The upper leg parallel connection assemblies of two front legs arranged below the outer car frame are symmetric with each other in a left and right mode, and two front-wheels type legs connected with the parallel connection assemblies are symmetric in a left and right mode. The upper leg parallel connection assemblies of two rear legs arranged below the inner car frame are symmetric with each other in a left and right mode, and two rear-wheels type legs connected with the parallel connection assemblies are symmetric with each other in a left and right mode. Each leg is in a (2-UPS+U) R series and parallel hybrid connection. The wheel-leg composite type four-leg robot has the advantages that the load is big, the rigidity is good, the coupling is small, the obstacle crossing advantage of the leg mechanism is fully applied, the complexity of the control and a mechanical structure is lowered, the installation is easy and convenient, and the maintenance is convenient. The positions and stress information of upper legs and lower legs can be obtained through sensors, and the self-adaption control in an unknown environment can be achieved.

The invention relates to a gear-rack transmission device and a difficult-to-fall safe drawer cabinet manufactured by the gear-rack transmission device, belongs to the technical field of transmission devices and furniture, and solves the technical problems so as to provide the gear-rack transmission device and the difficult-to-fall safe drawer cabinet without influencing overall movement or appearance. The invention adopts the technical scheme that according to the gear-rack transmission device, a first gear is fixed onto a linkage rotary rod, a second gear is arranged on the linkage rotary rodthrough a one-way bearing, a first rack meshes with the first gear, and a second rack meshes with the second gear; and according to the difficult-to-fall safe drawer cabinet, two sides of multiple drawers are arranged on a cabinet body through guide rails, a support body is arranged on the bottom part of a panel of a drawer on the lowest layer, the drawers are connected through a linkage device,the drawer on the lowest layer is opened along with the opening of any one drawer on the upper layer through the linkage device, and any one opened drawer on the upper layer is closed when the draweron the lowest layer is closed. The gear-rack transmission device and the difficult-to-fall safe drawer cabinet manufactured by the gear-rack transmission device provided by the invention are particularly suitable for families with kids.

The invention provides a machining method of an injection molding face gear electrode and an injection molding face gear. A face gear transmission principle is used, a three-dimensional vector diagram of the face gear is generated in a generating method through computer-assisted software, then the injection molding face gear electrode is machined through a numerical control lathe, a mold cavity of the face gear is machined in an electric spark discharge technology, and accordingly the face gear is formed by infection molding. Due to the fact that transmission data of the face gear and a cylinder gear is simulated in a computer, the machined infection molding face gear completely meets face gear transmission requirements in practice, data is accurate, the face gear is fixed on a table face to be machined through the numerical control lathe, deformation cannot happen, and therefore the machined injection molding face gear electrode is high in accuracy and low in transmission noise. What is important is that technologies such as gear inserting or gear rolling or gear grinding are not used in machining of the injection molding face gear electrode, so that special knives are of no need, and cost is greatly lowered.

The invention discloses an accessory transmission structure, comprising: a governor, an oil mist separator, two starter motors, a power input transmission mechanism, a governor transmission mechanism, an oil mist separator transmission mechanism, and a starter motor transmission mechanism. The power input transmission mechanism is laid out along a straight line, and its power input end is connected to the middle transmission mechanism in the case housing. The transmission mechanism of the speed governor is arranged and connected vertically to the power input transmission mechanism. The transmission mechanism of the oil mist separator and the transmission mechanism of the starter motor are sequentially arranged along the axial direction of the transmission mechanism of the governor, and the transmission mechanism of the oil mist separator is vertically connected with the transmission mechanism of the governor. The starter motor transmission mechanism is arranged symmetrically with respect to the axis of the speed governor transmission mechanism, and the two power output ends of the starter motor transmission mechanism are respectively connected to the corresponding starter motors along the axial direction. By designing an accessory transmission structure, the present invention can not only solve the problem of normal operation of the interior of the casing and the transmission system of the accessory, but also meet the requirements of the compact installation of the accessories on the casing of the casing.
