Multifunctional worm wheel rotation-friction arm

Abstract

The invention discloses a multifunctional worm wheel rotation-friction arm. The multifunctional worm wheel rotation-friction arm is divided into two types of automatic inflation and non-inflation styles. A shaft head of the automatic inflation type hollow worm wheel is provided with a convex shape compression lid which is externally welded with a gas inlet nozzle and is internally provided with an air chamber, and embedded with an oil seal at the upper part, the convex shape compression lid is connected to a shell of a worm decelerating machine, the inner hole of the oil seal and the shaft head of the worm wheel are sealed, a left connecting lug and a right connecting lug which are arranged on the lower shaft and are in an inverted concave shape are provided with two nuts in the same diameter respectively, the nuts movably connected to two holes of the diameter of a hollow cylindrical universal coupler through bolts, the two holes in the diameter of a lower cross are movably connected with two symmetrical hanging lugs arranged on the pipe top of the inflation rotation-friction arm through the bolts, and a water cage canvas pipe, a PPR hard plastic pipe, an alloy pipe, a stainless steel tube or a galvanized tube is adopted in the inflation rotation-friction arm. A zero damage inflation type glass cowhells latex fish tail fin type long finger is adopted to wipe various bright outer surfaces of limousines, buses, metros, trains, passenger cars, motor cars and high-rise buildings, a high resilience wear-resisting nylon wire rod or an alloy steep wire is adopted as a container, acid, alkali, salt and calcium in the inner wall of a jar or a pot is polished and cleaned in a water spraying process and then discharged from a pollution discharge valve, and a mushroom type foxtail type rotation-friction arm can conduct wiping in various kinds of ways such as a horizontal tilting mode.

Description

[0001] (1) Technical field: [0002] Invented and innovative multi-functional worm wheel wiper arm has two types, inflatable and non-inflated. The inflatable worm wheel wiper arm has a hanging wiper arm, a long horizontal lifting wiper arm and a foxtail and mushroom-shaped medium and small wiper arm, non-inflated The worm gear wiper arm is made of a combination of hard nylon screw or alloy steel wire and connecting parts. The inflatable worm gear wiper arm is used for the roof of cars, buses, subways, high-speed trains, railway passenger cars, express, express, and ordinary passenger cars. The left and right sides of the surface, the tempered glass window, and the varnished surface are environmentally friendly and water-saving one-time zero-damage wipe under the condition of spraying water from the pressure nozzle. The outer surface of the high-rise building is tempered glass and special-shaped surface. The round flat square edge decoration is used for top-down bar code scouring, ...

Problems solved by technology

[0004] At present, worm gear reducers are widely used in the machinery industry in China and other countries in the world. The output shaft of the worm gear is connected with various types of screw rods, gears, sprockets, V-belt sheaves, etc. with flat keys or splines to form a required transmission structure. The pressure gas of the compressor is connected through a rubber hose to form a structure that rotates and inflates in the seal. It is a difficult problem. In the original new sealed and inflated rotating structure, there is a hollow ventilation shaft with bearings, and the top of the shaft is connected to an air inlet connected to the rubber hose. Tsui, a bearing is installed on the boss neck of the hollow ventilation shaft, and a rubber leak-proof oil seal is inlaid on the bearing. The outer ring of the bearing is equipped with a large triangular belt grooved wheel. The small V-belt grooved wheel is driven, and the large V-belt grooved wheel is installed with a leak-proof rubber oil seal in the lower plane. The two protruding parts of the inverted concave shape are two connecting ears. The rotary seal inflatable transmission structure composed of hollow ventilation shaft and leak-proof oil seal, the air outlet nozzle of the hollow hollow ventilation lower shaft head is connected with a rubber air supply hose, and the other end of the hose passes through the hollow cylindrical universal coupling and connects with the rotating shaft. The rubber connection nozzle at the top of the wiper tube is connected, and the hollow cylindrical universal coupling has four holes with two diameters perpendicular to each other at the top and bottom of the cross, and two of them are connected with special bolts respectively. The ear and the two connecting ears on the top of the swivel arm tube form an inflatable swivel arm. This structure is well sealed, but the structure is complicated, and it is very difficult to manufacture, process and assemble. Now there is an optimized and streamlined innovative automatic inflatable multi-functional worm gear swivel arm. , the original worm gear hole with keyway is processed into a hollow shaft with internal ventilation, the outer circle of the upper shaft extension shaft head is sealed with a leak-proof oil seal, the lower shaft extension shaft head is concave-shaped, and the left and right hanging load-bearing lugs have two connections on the diameter. Nut, the outer circle of the leak-proof oil seal of the upper shaft extension shaft head is inlaid on the inner wall of the convex axle box gland. There is a small air chamber above the leak-proof oil seal, and the center of the top surface of the axle box gland An air supply rubber hose is welded on the hole to connect the air inlet nozzle, the other end of the rubber hose is connected to the outlet nozzle of the oil-free lubricated air compressor, the axle box gland is connected to the shell of the worm reducer with bolts, and the worm wheel ventilation shaft is under the The two concave-shaped connecting lugs of the shaft extension shaft head are symmetrically loaded on the same diameter, and the two fine-thread nuts are dynamically connected to the two connection holes on the diameter of the innovative hollow cylindrical universal joint with two special-type fine-thread bolts. The two connecting holes on the diameter of the lower cross are dynamically connected with the nuts on the two vertical connecting lugs on the diameter of the top surface of the swivel arm tube with special fine-thread bolts, and hundreds of zero-damage inflatable glass with cross-dislocation and uniform distribution of interlayers on the swivel arm Beef tendon latex fin-shaped wiping fingers and connecting nozzles are assembled into an innovative inflatable multi-functional worm gear swivel arm structure. The structure is creative, novel, transmission is reasonable, tooling is simple, and one arm is multi-functional, safe and practical.
