Description

Food machinery assembly line helical gear worm decelerating machine

Technical field

The utility model relates to reducer technology fields, and in particular to a kind of food machinery assembly line helical teeth worm and gear subtracts Fast machine.

Background technique

Speed reducer uses field very extensive, and for example automotive field, electronic product industry known to us, household electrical appliances are set Standby, Medical Devices moreover also relate to metallurgical, coloured, coal, building materials, ship, water conservancy, electric power, engineering machinery and stone The industry fields such as change.Especially helical gear worm decelerating machine has meshing performance good, and vibration is low, noise is small, stable drive.Weight It is right big, the load of each pair of gear teeth is reduced, the bearing capacity of gear is c correspondingly increased, the service life is long；Because of face contact, stress Area is big, and the torque of transmission is big, is usually used on heavy-duty machinery；Minimum teeth number of the helical gear minimum teeth number allowable than spur gear It is few, therefore helical gear is not susceptible to root and cuts；Oblique gear mechanism is compact compared with spur gear, small in size, light-weight, the spies such as transmission accuracy height Point.

Chinese utility model patent if notification number is CN204647151U disclosed one kind tiltedly on 09 16th, 2015 Gear worm speed reducer, has the motor with input shaft and the body with capping, and the body is connected by input shaft and motor It connecing, the output end of body uses flange arrangement, couples with driven equipment main body, and the input shaft is parallel with worm screw to be installed, Worm screw is vertical with output shaft installation direction, and output shaft is equipped with worm gear, and worm and wheel intermeshing, the both ends of output shaft are all provided with There is bearing, the both ends of worm screw are equipped with bearing, and one end of worm screw is connect by flat key with the input gear being located on input shaft.

Helical gear worm decelerating machine in the prior art, in closed speed reducer, every a pair of gear, which is meshed, to rub Wiping just will give off heat, and rise speed reducer the temperature inside the box gradually with the lengthening of the duration of runs according to boyle boyle's law Height, and decelerating chassis inner volume is constant, therefore pressure increases therewith in case, lubricating oil is splashed in cabinet, is sprinkled upon in decelerating chassis Wall.Since the permeability of oil is stronger, in the case under pressure, which place is poorly sealed, oily just wherefrom to ooze out.It is most of to slow down Machine is in such a way that rubber framework grease seal spring constraint epipharynx is friction sealed, since sealing effect is decided by finish, the axis of axis Beating degree, environment grit pollution etc. factors, after run a period of time, rubbing surface i.e. can generate motility gap, suction Investing the lubricating oil on axis can be flowed out except cabinet by this gap.Therefore there is spindle nose and let out in many equipment of factory site The phenomenon that revealing lubricating oil.

The normal operation of equipment is based on to the effective and reasonable lubrication of bearing, and discovery oil leak is possible to occur , there is accident in oil starvation scaling loss bearing phenomenon.Then once finding oil leak, the safeguard measure that can be taken in operation is exactly for operation It refuels in fuel tank, in dynamic, fuel tank is possible to a possibility that super oil condition occur, more increasing oil leak.
