Description
Technical field
The utility model belongs to valve field, is related to worm wheel head, especially a kind of new type worm wheel head.
Background technology
Valve is the control unit in fluid delivery system, for the valve of fluid control systems, from simplest cut-off
The valve various valves used into extremely complex robot control system(RCS), kind and specification are quite various.The worm gear of existing valve
Head, in housing worm gear and the site of engagement of worm screw be all coating lubricating oil to keep its rotation smooth, but need periodically to open
Worm wheel head make-up oil, and in actually using, it is pretty troublesome and unpractiaca to open worm wheel head.Therefore need one kind can not
Dismantle worm wheel head can make-up oil new type worm wheel head.
Utility model content
The purpose of the utility model is to overcome in place of the deficiencies in the prior art, a kind of new type worm wheel head is provided, it is not necessary to tear open
Opening worm wheel head can make-up oil.
The utility model technical scheme applied to solve the technical problem is：
A kind of new type worm wheel head, including housing, worm gear, worm screw, worm screw is connected and composed by inside and outside two sections of worm engaging, interior
Section worm screw, which is mounted in housing, engages connection with worm gear, and U-shaped is made in the outer end of outer section of worm screw, passes through in hand wheel handle insertion U-lag
Straight pin is connected with worm screw, and center is formed with an oil-through hole in worm screw, oil-through hole connection inner segment worm screw and outer section of worm screw, inside
Uniform intervals are formed with multiple oil outlets at screw thread on section worm screw, and oil outlet connects the outer end U-lag of oil-through hole, outside section worm screw
Bottom be formed with one connected with oil-through hole and diameter be more than oil-through hole mounting hole, embed charge of oil mouth, the handwheel in mounting hole
Handle corresponds to oil nozzle and is formed with a groove, and oil nozzle is embedded in groove, and oil nozzle outer ring surface is clamped or is threadedly coupled with mounting hole.
Moreover, the oil nozzle includes oil nozzle body, steel ball and spring, spring and steel ball, steel are co-axially mounted in oil nozzle body
Ball blocks the oil inlet of oil nozzle body.
Moreover, the oil outlet of oil nozzle installs oil cleaner screen in mounting hole.
The advantages of the utility model and good effect are：
1st, this worm wheel head housing for by worm screw oiling lubricating oil being made to flow in housing, Lubricating worm wheel and worm screw connect
Contact portion position, it is simple and quick without dismantling worm wheel head.
2nd, this worm wheel head is turned on and off oil inlet passage by steel ball and spring, and steel ball portion, structure are protected by hand wheel handle
Design is scientific and reasonable.
3rd, the import installation oil cleaner screen of this worm wheel head lubricating oil in worm screw, prevents impurity from entering worm gear head capsule with lubricating oil
In vivo, worm and gear is avoided to be worn.
Description of the drawings
Fig. 1 is the structure diagram of this worm wheel head；
Fig. 2 is the A portions enlarged drawing of Fig. 1.
Specific embodiment
Below in conjunction with the accompanying drawings and pass through specific embodiment the utility model is described in further detail, following embodiment is simply retouched
The property stated, be not limited, it is impossible to limit the scope of protection of the utility model with this.
A kind of new type worm wheel head, including housing 5, worm gear 8, worm screw, worm screw is connected and composed by inside and outside two sections of worm engaging,
Inner segment worm screw 7, which is mounted in housing, engages connection with worm gear, and U-shaped is made in the outer end of outer section of worm screw 3, and 1 handle of handwheel is inserted into U-lag
It is connected by straight pin 4 with worm screw.Center is formed with an oil-through hole 9, oil-through hole connection inner segment worm screw and outer section of snail in worm screw
Bar, uniform intervals are formed with multiple oil outlets 6, oil outlet connection oil-through hole at the screw thread on inner segment worm screw.Section worm screw outside
The bottom of outer end U-lag be formed with one connected with oil-through hole and diameter be more than oil-through hole mounting hole, embed charge of oil mouth in mounting hole
2, oil nozzle outer ring surface is clamped or is threadedly coupled with mounting hole.The oil nozzle includes oil nozzle body, steel ball 11 and spring 12, in oil nozzle
Spring and steel ball are co-axially mounted in vivo, steel ball blocks the oil inlet of oil nozzle body, the oil outlet installation oil strain of oil nozzle in mounting hole
Net 13.
The hand wheel handle corresponds to oil nozzle and is formed with a groove 10, and oil nozzle is embedded in groove, protects oil nozzle.
The application method of the utility model is：
Lower cylindrical pin is unloaded, pulls up handwheel, oil pipeline is inserted into oil nozzle, oily pressure can promote steel ball, and lubricating oil is suitable
Oil inlet to flow into oil-through hole.Oil transportation terminates, and recoil of spring, steel ball withstands oil inlet again.Oil cleaner screen can pass through taking-up
Oil nozzle regularly replaces.
Above-described is only the preferred embodiment of the utility model, it is noted that for the ordinary skill of this field
For personnel, on the premise of utility model design is not departed from, various modifications and improvements can be made, these belong to this reality
With new protection domain.
