Description

Speed reducer with centralized lubricating function for brick and tile making machine

Technical Field

The utility model belongs to the technical field of transmission equipment, concretely relates to speed reducer for brickmaking tile machinery with centralized lubrication function.

Background

The speed reducer is a power transmission mechanism that can convert the number of revolutions of a motor to a desired number of revolutions and can change torque. In the mechanism for transmitting power and motion at present, the application range of the speed reducer is quite wide, and the speed reducer can be seen in the transmission systems of various machines from ships, automobiles and locomotives of vehicles and heavy-duty machines for buildings. The bearing in the speed reducer is generally lubricated by lubricating grease, an oil pipe is communicated to the outside at a position needing lubricating, and the lubricating grease is injected inwards through the oil pipe when the lubricating grease needs to be added, so that the purpose of lubricating the bearing is achieved; the speed reducer for the existing brick and tile making machine is provided with a plurality of oil pipes for lubrication due to large volume at different positions, and when lubricating grease is injected, a handheld oil gun is required to inject around one speed reducer, so that the operation is inconvenient, the oil pipes required to be injected are easily omitted, the local part is not lubricated, and the operation of the speed reducer is influenced.

SUMMERY OF THE UTILITY MODEL

In to current speed reducer, lubricated oil pipe is not concentrated, omits easily when injecting lubricating grease, operates shortcoming such as inconvenient, the utility model provides a speed reducer for brickmaking tile machinery with centralized lubrication function, it is equipped with centralized lubrication device, can inject lubricating grease to all oil pipes at same position, makes lubricating grease can reach different bearing departments and lubricate.

The technical scheme of the utility model as follows: the speed reducer with the centralized lubricating function for the brick and tile making machine comprises a shell, bearings, oil pipes and a centralized oil injection device, wherein the bearings are arranged in the shell; concentrate oiling device includes the oiling piece of fixed connection on the casing, is equipped with a plurality of oilholes on the oiling piece, and the oilhole inner wall is equipped with the screw thread, and the fixed cover of the last access port department of oil pipe is equipped with threaded fastener, and threaded fastener passes through with the oilhole threaded connection of oiling piece inboard, fixes oil pipe in the oilhole, and oil pipe's tip stretches out in the oiling piece outside.

This scheme is through setting up concentrated oiling device on the speed reducer casing, all gathers all oil pipes in a department and injects the grease, not only can avoid frequent change position oiling, and according to the oiling of order can also the surface leak annotate, has still improved the efficiency of refueling simultaneously.

Furthermore, the centralized oil injection device further comprises a sealing oil injection nozzle arranged on the outer side of the oil injection block, the sealing oil injection nozzle is detachably connected to the orifice part of the oil hole and covers the end part of the oil pipe, the sealing oil injection nozzle is cylindrical, a circle of sealing layer is arranged on the inner wall of the sealing oil injection nozzle around the mouth part of the oil pipe, and a certain gap is reserved between the sealing layer and the oil pipe.

Because use the grease gun to oil pipe when refueling, the two interface is in and spills over easily under the grease injection pressure, drips on the box, pollutes the box, consequently sets up a sealed glib talker and can play sealed effect in oil pipe's port department, reduces the grease and spills over, with the grease shutoff that spills over in a small amount in the glib talker, simultaneously because the glib talker can dismantle the connection, can also pull down it after using a period and wash, it is more convenient to use.

Further, the sealing layer comprises a hollow rubber layer arranged close to the inner wall of the sealing oil injection nozzle, and a spring fastening framework arranged in the hollow rubber layer.
