Abstract
The invention discloses a water brake for a core drill. The water brake comprises a stator assembly fixedly connected with a shell. A rotor assembly is installed between the shell and the stator assembly. The upper end of the shell is communicated with a pressure gauge through a gauge connector. The rotor assembly is fixed to the end face of a rotor shaft through a baffle and a stop plate via a second bolt. A lug plate is arranged on the outer side of the stretching-out portion of the shell. A lead screw hole is formed in the lug plate. The outer end of the rotor shaft is sleeved with a gear. The gear is fixed to the rotor shaft through an elastic check ring for the shaft and an elastic check ring for the hole. According to the water brake, accurate detection of the pressure gauge is ensured, and the problem that the sealing performance is poor due to the fact that the pressure gauge is directly connected with the shell is solved; by means of the lug plate arranged on the outer side of the stretching-out portion of the shell, stable installation of the water brake is ensured; and the gear is fixed to the outer end of the rotor shaft through the elastic check ring for the shaft and the elastic check ring for the hole, so that the requirements of the market for different water brake performances are met compared with the existing sliding gear design.
