Abstract
The utility model discloses a lubricating grease filling structure convenient for lubricating a portal frame. A first oil duct is radially formed in a bearing; a third oil duct is formed in a center shaft of a wheel axle; a lubricating nozzle is mounted at the front end of the third oil duct; a second oil duct is formed in the position, corresponding to the first oil duct, of the side surface of the third oil duct; the first oil duct and the second oil duct are located on the same axis and connected with each other. The lubricating grease filling structure disclosed by the utility model realizes disassembly-free lubrication for the portal frame, especially under the situation that a chain wheel and the bearing are difficult to disassemble, avoids damage caused by misoperation, further prolongs the service life of an idler wheel and the bearing, especially reduces the maintenance cost and the labor time for the portal frame in a refrigeration house environment, and allows the maintenance to be more efficient and timely.
Description
Technical field
The utility model relates to a kind of grease up structure of being convenient to lubricated door frame.
Background technique
Bearing is in mechanical transmission course, to work the parts of fixing and reducing load friction factor.,, in the time that other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor and retainer shaft central position in power transmission process.Bearing is a kind of very important component in contemporary machinery.Its major function is supported mechanical solid of rotation, the mechanical load friction factor in order to reduction equipment in transmission process.
In prior art, for keeping door frame to promote and the normal work that declines, the sprocket wheel on door frame and bearing need to remove grease up conventionally.And when bearing for sealing local time, be but not easy grease up.As for forklift door frame promote bearing, dismounting sprocket wheel and bearing inconvenience, once dismantle improper, easily damage wheel shaft surface and bearing, and till the sprocket wheel of sealed type and bearing can only use and may wear to and cannot normally work, grease up again, cost is higher.
Therefore, the inventor designs a kind of grease up structure of being convenient to lubricated door frame, and this case produces thus.
Model utility content
The purpose of this utility model is to provide a kind of grease up structure of being convenient to lubricated door frame, to avoid causing because of misoperation the damage of wheel shaft surface and bearing, and efficient more in time to the maintenance of door frame.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of grease up structure of being convenient to lubricated door frame, on bearing, radially offer the first oil duct, on the central shaft of wheel shaft, offer the 3rd oil duct, the front end of the 3rd oil duct is provided with fuel filler neck, the second oil duct is offered in the position of corresponding the first oil duct in the side of the 3rd oil duct, and the first oil duct and the second oil duct are in same axis and interconnect.
Described wheel shaft external diameter is provided with the circular groove that connects the first oil duct and the second oil duct.
Described fuel filler neck is provided with outside thread, and the 3rd oil duct is provided with internal thread, by coordinating of outside thread and internal thread, fuel filler neck is connected with the 3rd oil duct.
Adopt after such scheme, the utility model has been realized the dismounting of exempting from of door frame has been lubricated, particularly the in the situation that of sprocket wheel and bearing removal difficulty, avoid the damage causing because of misoperation, and then extended the working life of roller and bearing, especially under freezer environment, reduced maintenance cost and the man-hour of door frame, made to safeguard efficient more in time.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic perspective view of the utility model wheel shaft.
Label declaration
Wheel shaft 1, fuel filler neck 2, the three oil ducts 3, screw 31, the second oil duct 4, the first oil ducts 5, circular groove 51, die cavity 52, bearing 6.
Embodiment
As depicted in figs. 1 and 2, the utility model has disclosed a kind of grease up structure of being convenient to lubricated door frame, on bearing 6, radially offer the first oil duct 5, on the central shaft of wheel shaft 1, offer the 3rd oil duct 3, the front end of the 3rd oil duct 3 is provided with fuel filler neck 2 and rear end seals by screw 31, and screw 31 can play fixation to bearing 6 simultaneously.This embodiment's fuel filler neck 2 is provided with outside thread, and the 3rd oil duct 3 is provided with internal thread, by coordinating of outside thread and internal thread, fuel filler neck 2 is connected with the 3rd oil duct 3.The second oil duct 4, the first oil ducts 5 and the second oil duct 4 are offered in same axis in the position of corresponding the first oil duct 5 in the side of the 3rd oil duct 3.
For the ease of installing, this embodiment's wheel shaft 1 external diameter is provided with the circular groove 51 that connects the first oil duct 5 and the second oil duct 4.Even if the first oil duct 5 and the second oil duct 4, not on same axis, by the introducing of circular groove 51, also can make lubricating grease successfully flow in the first oil duct 5 from the second oil duct 4.Therefore, this kind of structure not only reduced installation requirement, and improved lubrication effect.
The utility model in use, attendant can utilize the nozzle with pressure, lubricating grease is pressed in the circular groove 51 wheel shaft 1 external diameter through the 3rd oil duct 3 and the second oil duct 4 from fuel filler neck 2, in circular groove 51, be full of after lubricating grease, lubricating grease arrives in the die cavity 52 of bearing 6 by the first oil duct 5 again, plays the lubrication to bearing 6.
The utility model has been realized the dismounting of exempting from of door frame has been lubricated, particularly dismantle difficult in the situation that at sprocket wheel and bearing 6, avoid the damage causing because of misoperation, and then extended the working life of roller and bearing 6, especially under freezer environment, reduce maintenance cost and the man-hour of door frame, made to safeguard efficient more in time.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, suitable variation or modification that any person of an ordinary skill in the technical field does it, all should be considered as not departing from patent category of the present utility model.
