Compared with prior art, advantage of the present utility model is.
1, this machine uses air as the medium that transmits energy, draws horse relatively with mechanical type, has that locating speed is fast, an advantage of cheapness and high efficiency; Draw horse relatively with fluid pressure type, no hydraulic oil pollution is arranged, do not need to regularly replace hydraulic oil, reduced use cost, and weight is lighter, good portability; Draw horse relatively with the pneumatic of other type, because this machine is integrated in air-breathing cylinder (power cylinder) and draws at once, this has not just needed gas supply station, can not be subjected to limit from the tracheae length that fixed gas source is stood out when drawing horse work, thereby the working region scope is affected, makes portability and operation flexibility improve greatly;
2, owing in gas circuit, be provided with duck-beak type check valve (standard component), make the more steady of operating air pressure and air-flow, so this machine is more suitable for dismantling the higher bearing of precision.This machine compact conformation, light portable, high efficiency, easy to operate, the diameter range of dismountable bearing is big, uses safety, required location is short non-cutting time, have high performance-price ratio, do not need independently advantage such as gas supply station, and in actual production, receive good effect.
3, this machine is provided with cover three axles top (7,11,14), and wherein two are installed on left and right two end faces of lateral frame when not using, and play the effect of stop, and slippage is colluded in two bearing drawings about preventing.
