Abstract
The invention discloses a special grease injection control head for injecting grease to the rubber part of an external oil seal component. An oil separation positioning disk locates through a positioning sub-opening of a connection tray and is provided with a seal groove 1; the oil separation part of the oil separation positioning disk is matched with the rubber seal groove of the external oil seal component and radially locates and seals the rubber seal groove; the axial positioning face of the oil separation positioning disk axially locates the large end face of the external oil seal component; an oil injection head is located in the oil separation positioning disk, and the axial positioning end face thereof is provided with a seal groove 2 and a seal ring 2; the circumference of the oil injection head is evenly provided with 36 holes at intervals; and a small magnitude of interference is left between the circumferential outer diameter of the oil injection head and the internal diameter of the rubber lip mouth of the external oil seal component. In the invention, not only can the rubber lip mouth part be correctly injected with grease to maintain the uniformity of lubricating grease on the circumference of the lip mouth part of the external oil seal component after grease injection, but also impurities can be reduced to be attached to the lip mouth of the external oil seal component to prevent the impurities from entering into a bearing, thereby effectively prolonging the service life of the bearing.
Description
Technical field
The present invention relates to greasing equipment, be specifically related to the special-purpose greasing head of greasing equipment.
Background technique
At present, the position greasing of known outer oil seal assembly lip is manually to smear with labiad oral thermometer faces such as hairbrush, rags to form.The mode of so outside Oil sealing assembly greasing causes lip surface greasing difficulty, can not control its greasing weight according to industry requirement, and cause the circumferential skewness of greasing amount of same outer oil seal assembly after the greasing, very big with the greasing weight difference of a collection of outer oil seal assembly.Also have the fibre object of hairbrush, rag to drop, and enter bearing inside, influence the traffic safety of railway truck bearing on its lip surface.There is not the special-purpose greasing head of a kind of greasing so far to railway freight-car rolling bearing outer oil seal assembly rubber lip position.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, a kind of external Oil sealing assembly rubber special-purpose greasing head that greasing is carried out at the position is provided, at outer oil seal assembly rubber position specialized designs, be specially adapted to correct greasing is implemented at its lip rubber position, guarantee in the greasing process, grease can be evenly distributed, and the rubber position does not produce distortion, and lubricating grease can be stored in good form in the rubber lip position.
For solving above-mentioned technical problem, the present invention by the following technical solutions:
The special-purpose greasing head that greasing is carried out at a kind of external Oil sealing assembly rubber position, comprise land, oil removal positioning disk, oiling head, land is installed on the platform of grease filling machine, the oil removal positioning disk positions by the rim of the mouth, location of land, and have a seal groove one, seal groove one is equipped with seal ring one, the oil removal position of oil removal positioning disk and outer oil seal assembly rubber seal groove match and merge external Oil sealing assembly enforcement radial location and seal action, the soft position of the rubber of outer oil seal assembly relies on the circular step on oil removal positioning disk top to prevent to move radially when oiling; The axial locating surface of oil removal positioning disk carries out axially locating with the large end face of outer oil seal assembly; The oiling head is positioned at the inside of oil removal positioning disk, carry out axially locating by oil removal positioning disk internal end surface, the axially locating end face has seal groove two, and installation seal ring two prevents that grease from oozing out, at least 36 holes that distributing uniformly, the circumferential interval of oiling head, the circumferential outside dimension of oiling head and the rubber lip internal diameter size of outer oil seal assembly have slight magnitude of interference; The sealing at outer oil seal assembly lip position relies on itself and cooperating of oiling head to finish.
Further technological scheme is:
The radial location of described oiling head and oil removal positioning disk relies on two taper pins to finish.
Described oiling head circumferentially equally distributed hole, interval is the long waist shaped hole.
Described land is connected with bolt one with the oil removal positioning disk, and the oil removal positioning disk is connected with bolt two each other with the oiling head.
Compared with prior art, the invention has the beneficial effects as follows: this special use greasing head can not only be implemented correct greasing to its lip rubber position, the uniformity of the lubricating grease circumferential distribution in Oil sealing assembly lip position outside after the maintenance greasing, good seal performance, lubricating grease all can enter in the lip position of outer oil seal assembly, can guarantee that the oil mass that grease filling machine provides do not lose.Can also reduce impurity and enter on the outer oil seal assembly lip, stop impurity and enter bearing inside, effectively improve bearing working life.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
The present invention is further elaborated below in conjunction with accompanying drawing.
As shown in Figure 1, the special-purpose greasing head that greasing is carried out at a kind of external Oil sealing assembly rubber position, comprise land 1, oil removal positioning disk 2, oiling 9, land 1 is installed on the platform of grease filling machine, oil removal positioning disk 2 positions by the rim of the mouth, location of land 1, and have a seal groove one, seal groove one is equipped with seal ring 1, match with outer oil seal assembly 3 rubber seal grooves in the oil removal position of oil removal positioning disk 2, and externally Oil sealing assembly 3 is implemented radial location and seal action, the soft position of the rubber of outer oil seal assembly 3 relies on the circular step on oil removal positioning disk 2 tops to prevent to move radially when oiling; The axial locating surface of oil removal positioning disk 2 carries out axially locating with the large end face of outer oil seal assembly 3; Oiling 9 is positioned at the inside of oil removal positioning disk 2, carry out axially locating by oil removal positioning disk 2 internal end surface, the axially locating end face has seal groove two, and seal ring 27 is installed is prevented that grease from oozing out, and oiling 9 relies on two taper pins 4 to finish with the radial location of oil removal positioning disk 2.The purpose of taper pin 4 mainly is to allow oiling 9 radially accurately be positioned on the oil removal positioning disk 2, guarantee that the outer oil seal assembly is put into after, its rubber position and greasing head are engaged in the circumferential direction uniformity.Guarantee that inner space, outer oil seal assembly 3 lip position is circumferentially even.
36 the long waist shaped holes that distributing uniformly, the circumferential interval of oiling 9, the circumferential outside dimension of oiling 9 and the rubber lip internal diameter size of outer oil seal assembly 3 have slight magnitude of interference; The sealing at outer oil seal assembly 3 lip positions relies on itself and cooperating of oiling 9 to carry out, and land 1 is connected with oil removal positioning disk 2 usefulness bolts 1, and oil removal positioning disk 2 and oiling 9 is connected with bolt 28 each other.
The long waist shaped hole of greasing head 9 is The more the better.According to the mechanical processing technique horizontal constraints, 36 is most economical.Even greasing can be guaranteed, this greasing head can be processed easily again.
The effect of this specific embodiment is: impurity can not enter on the outer oil seal assembly lip, and outer oil seal assembly lip position grease distributing homogeneity improves greatly, and after bearing assembling, it is good initial lubricated that the lip position can provide, and effectively improves bearing working life.
