Proposed is a two-stage machine tool gearing, in particular spindle gearing, comprising a planetary gear set (16), in which the spindle (7) or a spindle insert can be connected in a form-fitting or force-fitting manner to the drive output (2, 3) of the gearing (17), which gearing (17) has a first drive output shaft (2) and a second drive output shaft (3), wherein the first drive output shaft (2) is rotationally fixedly connected to the drive input shaft (1) and can be detachably connected by means of a first switching element (5) to the sun gear (4) of the planetary gear set (17), wherein the second drive output shaft (3) is rotationally fixedly connected to the web (19) of the planetary gear set (17) and the ring gear (8) of the planetary gear set (17) is rotationally fixedly connected to the housing (18) of the gearing, and wherein a second switching element (6) is provided which produces a detachable connection between the spindle (7) or a spindle insert and, selectively, the first or the second drive output shaft (2) or (3).

The invention provides an automatic rotation type coke cutter, belongs to the technical field of hydraulic decoking, and mainly solves the problem that two working conditions including drilling and coke cutting cannot reach an optimal matching state since an existing coke cutter only can provide one pre-set rotary speed. The automatic rotation type coke cutter is mainly characterized by comprising a drilling rod connection part, a water power part, a throttle governing part, a decoking part and a switching part, wherein the throttle governing part is arranged between the water power part and the decoking part; the switching part is arranged in an axial cavity of the decoking part; the upper rend of a switching shaft is connected with a switching disc by a spline; the switching disc is provided with two switching blocks; a water supply flow channel of the decoking part is an inner annular flow channel; four or two coke cutting nozzles are distributed at the periphery of the water supply flow channel and four drilling nozzles are distributed at the bottom end of the water supply flow channel. The automatic rotation type coke cutter has the characteristics of providing rotation speeds meeting the two working conditions including the drilling and the coke cutting respectively and being good for removal of buried drilling when coke in a tower collapses and is power equipment capable of being widely applied to a hydraulic decoking process in the coke tower.

The invention relates to a turbocharger. The turbocharger comprises a middle body. The two ends of the middle body are connected with an impeller and a turbine correspondingly through shafts, the outside of the impeller is covered with a pressure air shell, a shock absorber is installed on the lateral surface of a pressure air shell outlet, an air inlet is formed in one side of the impeller, and the turbine is provided with a turbine air inlet and a waste gas outlet. A turbine shell of the turbocharger is not provided with a bypass vent valve but the shock absorber, so that the knock and surge phenomena are avoided. Pressure is adjusted through a precise spring of the shock absorber sensitively and reliably, and installation, debugging and repairing are convenient. The turbocharger is adjusted through an adjusting screw when matched with an engine and debugged, operation is simple, accurate and reliable, and a technician of an engine factory assembly production line and a vehicle repairing technician can install and debug the turbocharger according to the power, displacement and revolution number of the engine to meet the ideal standards.

The invention discloses a method for preparing a latex-free woven carpet. The second coating layer is hot-melt fiber filament or staple yarn, and the first coating layer is high-density polyethylene fiber filament or staple fiber. yarn, the second covering layer accounts for 20%-50% of the total mass of the composite yarn, the first covering layer accounts for 10%-15% of the total mass of the composite yarn, and the rest is the core yarn to obtain the hanging pile weft yarn. When using hot-melt ethylene-vinyl acetate copolymer fibers as bonding materials to produce adhesive-free carpets, and with pile yarns made of nylon fibers or wool, when hot-melt ethylene-vinyl acetate copolymer fibers are used in the heat-pressing process When it is heated above its melting point, it melts, and the conformation of the fiber macromolecular chain changes. Through the transition of the chain segment, the entire macromolecular chain slips and viscous flow occurs. The pull-out strength of the pile and the shape retention and dimensional stability of the carpet are improved, thereby omitting the adhesive backing process in the carpet preparation process, and making the prepared carpet more environmentally friendly.
