At present, the rotary vibrating unit head main shaft supporting that most of producer uses all uses cylindrical roller bearing or the combination of centripetal plane bearing, and it bears alternating stress ability, equipment adjustment difficulty.
Summary of the invention
The purpose of this utility model provides one to bear strong, the convenient for assembly adjustment of alternating stress ability and replacing, can improve rotary vibrating unit head working stability to solve prior art Problems existing, ensures the rotary vibrating unit head main shaft device of probing quality.
The technological scheme realizing the utility model object is as follows:
A kind of rotary vibrating unit head main shaft device, include the main shaft be installed in main spindle box body, be installed on respectively the top crossed roller bearing of main shaft upper end axle journal to the bottom crossed roller bearing pair being installed on main shaft lower end journal; Inner ring interior edge face and the main shaft axle journal end face of the inner side crossed roller bearing of every secondary crossed roller bearing centering are fitted; The inner ring exterior edge face of the intersect outside roller bearing of top crossed roller bearing centering is successively by embracing the locking of ring, anchor ear and circlip for shaft, and outer ring relies on upper press cover and locking nut locking, is provided with spacer ring between outer ring and upper press cover; The outer ring of the intersect outside roller bearing of bottom crossed roller bearing centering and inner ring, by lower cover and locking nut locking, are provided with lower spacer ring between outer ring and lower cover; Cone spacer and outer ring spacer is respectively arranged with between inner ring between two crossed roller bearings of every secondary crossed roller bearing and outer ring; The mating face of lower cover and main shaft is provided with labyrinth seal ring, upper press cover and lower cover offer respectively can by lubricant oil from external oil pipe introduce crossed roller bearing to the upper oil duct right with lower crossed roller bearing and lower oil duct.
The utility model is also provided with O RunddichtringO between main shaft and the mating face of lower cover.
The utility model adopt two secondary crossed roller bearings up and down to adjusting preloading respectively, need only match grinding cone spacer and outer ring spacer adjustment every secondary crossed roller bearing two crossed roller bearings between gap.Set upper oil duct and lower oil duct can respectively to upper crossed roller bearing to lower crossed roller bearing to lubricating at regular time and quantity, the spindle unit avoiding rotary vibrating unit head to cause owing to working under heavily loaded alternating stress effect generates heat excessive problem.Adopt labyrinth seal ring effectively to seal to main shaft lower end, can effectively prevent the rotary vibrating unit head inside worked under dust plaster environment by intrusion dust.
The utility model is simple and reasonable, and processing and assembling need not Special Equipments, adjustment convenient for assembly.It bears alternating stress ability by force, can effectively improve rotary vibrating unit head working stability, ensures carrying out smoothly of probing work.
Content of the present utility model is set forth further below in conjunction with Figure of description.
