Summary of the invention
The object of the invention is to solve above-mentioned the deficiencies in the prior art, provide that a kind of easy to operate, novel structure, precision are high, lightweight, energy-conserving and environment-protective, Safety performance is high, barrier propterty is high, the astragal formula dynamic balancing axle of beautiful shape.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of astragal formula dynamic balancing axle, be provided with balance axle, balance belt wheel and Cock screw, balance axle is the centering shaft part by the fixing shaft part of balance belt wheel and fixing shaft part one end, the connection shaft part of the other end is coaxially formed by fixedly connecting, it is characterized in that being provided with balance swivel nut, described connection shaft part is tapering shaft part, described balance swivel nut endoporus is to be communicated with and to be formed by the tapered hole of described concentric and the tapped hole of tapered hole small end, tapered hole equates with the tapering of tapering shaft part, the tapering shaft part of balance swivel nut one end and balance axle socket-connects, the other end is threaded with rotor through screw thread, be beneficial to eliminate the matching gap of rotor and trunnion shaft, and be convenient to dismounting.
The present invention can be in tapering shaft part two side respectively correspondence be provided with keyway, flat key and the tapering shaft part of balance swivel nut in keyway is fixedly sleeved, is beneficial to offset the throw of eccentric of dynamic balancing axle and rotor,
The present invention also can be provided with scale label at balance belt wheel end face, and scale label is ring panel, and panel surface circle is shown scale, reaches the convenient non-equilibrium site of determining accurately rotor.
The length of Cock screw of the present invention is the half of balance belt wheel wall thickness, is beneficial to reduce the amount of unbalance of trunnion shaft self.
The present invention is owing to adopting said structure, has the advantages such as easy to operate, novel structure, precision are high, lightweight, energy-conserving and environment-protective, Safety performance is high, barrier propterty is high, beautiful shape.
