Abstract
The utility model relates to the technical field of screw machines, in particular to a screw machine refrigerating tool. The tool comprises a cylinder, wherein the outer surface of one end of the cylinder is provided with a rotating rod, the rotating rod is vertical to the axis direction of the cylinder, the inside of the other end of the cylinder is provided with a cylindrical nut placement space, and the end face of the end of the cylinder is provided with locking nut buckling columns which are at least two in number. The inner side of the nut placement space is further provided with a cylindrical space with a diameter smaller than that of the nut placement space, and the cylindrical space is communicated with the inside of the cylinder. According to the installation depth of a bearing locking nut, the cylinder of a proper length is selected, by knocking the rotating rod on the cylinder, and a moment of couple is transmitted to the locking nut buckling columns at the bottom of the tool through a cylinder carryover moment, so that the bearing locking nut is locked. According to the screw machine refrigerating tool, assembling efficiency of the bearing nut of the screw machine is improved, and a bearing is not prone to being damaged.
Description
Technical field
The utility model relates to screw machine technical field, specifically a kind of screw mechanism cold frock.
Background technology
Existing screw machine is in the time of assembling screw machine negative and positive rotor end-face top bearing lock nut, mainly with chisel, knock by hammer, locking bearing locking nut, but because the bearing locking nut installation site of screw machine is at internal body, there is certain degree of depth, bring great inconvenience at fit on to conventional method, in the time of assembling, inconvenience is exerted all one's strength, and due to angle problem, easy damaged bearing locking nut, if number of patent application is CN201110435028.4, the applying date is 2011-12-22, name is called the patent of invention of " waste-heat power generation type screw rod unit ", its technical scheme is: a kind of waste-heat power generation type screw rod unit, it is characterized in that described screw rod unit comprises cooling cycle system and twin-screw expander system, the power output shaft of described twin-screw expander system is connected with an electricity generation system, the condenser coil of described cooling cycle system is positioned at the generator of described twin-screw expander system.Not for how, the nut on tie down screw machine rotor does not carry out technological improvement to the screw rod unit of above-mentioned patent, so still exist assembly method efficiency low and easily damage the problem of locking nut.
Summary of the invention
Low and easily damage the problem of locking nut in order to overcome the assembly method efficiency existing in prior art, now special to propose a kind of efficiency of assembling high, and the screw mechanism cold frock of easy damaged locking nut not.
For achieving the above object, technical solutions of the utility model are as follows:
A kind of screw mechanism cold frock, it is characterized in that: comprise cylindrical shell, outer surface in described cylindrical shell one end is provided with dwang, described dwang arranges perpendicular to tubular axis direction, the other end inside of described cylindrical shell is provided with cylindric nut placement space, be provided with locknut button column at the end face of described end, described locknut button column is at least two.The described inner side at nut placement space is also provided with the cylindric space that diameter is less than nut placement space, and cylindric space communicates with inner barrel.
Described dwang is at least two, and the angle that two dwangs form is 180 degree.
The external diameter of described cylindrical shell one end is less than the cylindrical shell other end that is provided with nut placement space.
Described two locknut button columns are symmetrical arranged with respect to tubular axis direction.
The utility model has the advantage of:
1, the utility model can be according to the fitting depth of bearing lock nut, selects suitable cylindrical shell length, and by knocking the dwang on cylindrical shell, the moment of couple to frock bottom locknut button column, is locked bearing lock nut with this by cylindrical shell carry-over moment.The utility model has improved the efficiency of assembling screw machine bearing locking nut, not fragile bearing.
2, dwang of the present utility model is simple in structure, power can easily be passed to locknut button column by cylindrical shell.
3, the utility model blocks nut by locknut button column, and drives thus rotation and then the locking nut of nut, has reduced the difficulty of locking this nut.
