Oil pump nozzle processing electricity consumption main shaft
Technical field
The utility model relates to the processing technique field of oil pump nozzle, particularly relates to a kind of oil pump nozzle processing electricity consumption main shaft.
Background technology
Oil atomizer develops to the direction of porous number, small-bore, but crudy directly influences the characteristic of oil atomizing, and oily line biography degree and flow coefficient, and the economy of final decision machine, dynamic property and discharge index are so the processing of oil atomizer is particularly important.
What generally adopt on the market now is air grinder, the characteristics of air grinder are: the compressed air that utilizes air compressor to produce, drive the fan blade of air grinder rear end then, thereby make it fast rotational driving bistrique and carry out processing work, its feature is that the gas static pressure supports, rigidity is poor, and maintenance is difficult.Simultaneously, in conversion process of energy, caused the waste of the energy because the driving of air grinder is to utilize electric energy to be converted to wind energy to convert kinetic energy again to and process, uneconomical.
The utility model content
The purpose of this utility model is at the problems referred to above, proposes a kind of oil pump nozzle processing electricity consumption main shaft, and that the electric main shaft of this utility model has is simple in structure, use advantages such as easy to maintenance, energy-conservation.
The technical solution of the utility model is: a kind of oil pump nozzle processing electricity consumption main shaft, contain housing and be installed in the interior armature spindle of housing, before the two ends of described housing are separately installed with, the rear bearing box, described armature spindle two ends by Bearing Installation in bearing box, enclosure interior is installed on stator module, the rotor assembly of coupling is installed on the armature spindle, rear bearing box rear portion is provided with back nut, be provided with spring in this back nut and be fitted in the middle part of rear bearing box, be provided with ring-shaped water jacket in the described housing, this ring-shaped water jacket position is corresponding with the position of stator module, and this ring-shaped water jacket is communicated with extraneous cooling water channel by intake-outlet.
The described rear bearing box outside is installed in the inside of housing rear end by linear bearing.
Described fore bearing box is fixedly mounted on the housing front end by securing member, and the bearing capping is installed on the fore bearing box.
The outer end that described armature spindle front end stretches out the fore bearing box is equipped with the cutter installing mechanism.
Described housing middle part is a cannelure, and this cannelure is set with the ring-shaped jacket body outward, forms described ring-shaped water jacket.
Described stator module passes housing by lead and connects power supply.
The beneficial effects of the utility model
The electric main shaft of utility model directly changes into kinetic energy with electric energy, has advantages such as simple in structure, that use is easy to maintenance, and is energy-conservation.
The rotating speed height of this main shaft, power is little, and the structure by adding water jacket can increase the service life to the bearing cooling of lowering the temperature.
