The utility model relates to an oilless compressor which comprises a crankcase, the crankcase is connected with an air cylinder box, a crankshaft is arranged in the crankcase and connected with an air cylinder through a connecting rod, the air cylinder reciprocates in the air cylinder box, balancing weights are arranged at the two ends of the crankshaft, a transmission shaft is fixedly connected to the rotating center of the balancing weight on one side, and a transmission shaft is fixedly connected to the rotating center of the balancing weight on the other side. The transmission shaft penetrates through the bearing box to be connected with the transmission wheel, the bearing box is connected with the crankcase, the transmission shaft is connected with the bearing box through a bearing, and the shaft diameter of the transmission shaft is not smaller than one third of the sectional area of the balancing weight. According to the oilless compressor, the balancing weights are arranged at the two ends of the crankshaft, the rotating center of the balancing weight on one side is fixedly connected with the transmission shaft, the crankshaft is supported only through the transmission shaft, vibration of the crankshaft is completely transmitted to the transmission shaft, the crankshaft is not connected with the crankcase, and vibration of the crankshaft cannot be transmitted to the crankcase; vibration of the crankcase can be reduced, and therefore vibration noise is reduced.

The application provides a bearing assembly for chemical mechanical polishing, comprising a damping module, a driving module and a bearing head; wherein the damping module comprises a spindle with a cavity inside and a first damping unit in the cavity, the first damping unit comprises a core and a plurality of damping blocks arranged on the outer wall of the core, the damping blocks extrude the inner wall of the cavity to absorb the transverse vibration of the spindle. The core is placed in the spindle, which enhances the damping and anti-vibration effect, in addition, the plurality of damping blocks arranged on the outer wall of the core can absorb the transverse excitation generated from the polishing head grinding, the compression resistance of the damping blocks is fully utilized, the original shearing and tensile working state is changed to a compression working state, the transverse damping capacity is increased, and the reset and limiting effects are also exerted.

The invention discloses a dual explosion-proof device, relates to the technical field of safety protection, and is used for solving the problems that an explosion-proof box in the prior art is difficult to prevent further explosion of explosives and the protection degree of sympathetic detonation is relatively weak. The dual explosion-proof device comprises an outer explosion-proof box assembly, an inner explosion-proof box assembly, a flame-retardant assembly and an explosion-proof buffer layer, wherein the inner explosion-proof box assembly, the flame-retardant assembly and the explosion-proof buffer layer are arranged in the outer explosion-proof box assembly. The flame-retardant assembly is arranged around the inner explosion-proof box assembly, and the explosion-proof buffer layer is arranged between the outer explosion-proof box assembly and the flame-retardant assembly. Double protection can be provided for explosives, disposal measures can be automatically taken in time when the explosives are abnormal, further explosion of the explosives is prevented, the risk of sympathetic detonation is reduced, the influence of the explosives on the surrounding environment is reduced, and safety is improved.

The invention relates to the technical field of automatic equipment for plate processing, in particular to a trimming device of a high-precision edge banding machine, which comprises a main frame, a first trimming mechanism and a second trimming mechanism, and the main frame is integrally welded; the first trimming mechanism is mounted on the main frame in a sliding manner; the second trimming mechanism is installed on the main frame in a sliding mode, and the first trimming mechanism and the second trimming mechanism have the function of trimming the edge sealing side of the plate. The first trimming mechanism is connected with the main frame through a first transmission part; the second trimming mechanism is connected with the main frame through a second transmission part, and the first transmission part and the second transmission part have the functions of high precision and small gap. The main frame is integrally welded, so that the problems of rigidity loss and large vibration caused by a traditional multi-piece assembly mode are reduced; the first transmission part and the second transmission part respectively have the characteristics of high precision and small gap, so that the mechanical gap during the operation of the trimming mechanism is reduced, and the guide precision and the stability are enhanced.
