Abstract
The utility model provides a shaft sleeve used in a rocker arm of a coal cutter, which aims at prolonging lubrication duration between the shaft sleeve and a transmission shaft, reducing maintenance frequency and improving operation speed and working amount and comprises an outer wall and an inner wall. A groove used for placing lubricant is arranged on the inner wall. The shaft sleeve increases filling amount of the lubricant, prolongs lubrication duration, improves lubrication evenness, reduces maintenance frequency and improves operation speed and working amount due to the fact that the groove used for storing the lubricant (like solid lubricant) is arranged on the inner surface of the shaft sleeve.
Description
Technical field
The utility model relates to the axle sleeve that a kind of rocker arm of coal mining machine uses.
Background technique
The turning joint of coal winning machine mostly is to connect with power unit through transmission shaft at present, and the axle sleeve that is arranged on transmission shaft is for the normal use of transmission shaft and the effect of playing protection working life and ensureing; It is general between axle sleeve and the transmission shaft that what adopt is between its surface of contact, to add similarly lubricant oil such as butter; Need constantly to check in time and additional butter, under the big situation of engineering work load, need frequent interpolation, and need clean surface of contact when adding new lubricant oil; More loaded down with trivial details; Maintenance work is relatively arduous for this reason, and frequent maintenance must influence coal mining speed, and then influences the performance of enterprises.
Summary of the invention
The purpose of the utility model provides the axle sleeve that a kind of rocker arm of coal mining machine uses, and to improve lubricating often between axle sleeve and the transmission shaft, reduces maintenance frequency, improves operating speed and workload.
For reaching above-mentioned purpose, the axle sleeve that the utility model provides a kind of rocker arm of coal mining machine to use, comprise outer wall and and inwall, its special way is that this inwall is provided with the groove that is used to put oiling agent.
Above-mentioned groove extends axially along said inwall.
Above-mentioned groove is along said inwall extending circumferentially.
Above-mentioned groove evenly is arranged on the said inwall.
Above-mentioned outer wall is provided with the filling hole in order to the packing lubrication agent that communicates with groove.
Above-mentioned filling hole is a plurality of, evenly is arranged on the outer wall.
The above-mentioned groove or the hole of hiding are the array-type setting, and adjacent grooves or the distance between the hole of hiding are 2.5 to 6.5mm.
The above-mentioned hole of hiding is circular, and its internal diameter is 1 to 2.5mm, and the degree of depth is 1 to 1.5 mm.
The utility model has the advantages that: the groove that kind of lubricant storage (like solid lubricant) is set through the internal surface at axle sleeve; Increase the loading of oiling agent, prolonged lubricated duration, improved lubricated uniformity; Reduce maintenance frequency, improved operating speed and workload.
Description of drawings
Combine accompanying drawing and embodiment that the utility model is elaborated at present:
Fig. 1 is the structural representation of the universal joint that provides of the utility model.
Fig. 2 is the structural representation that the surface is provided with the bearing pin of the groove that radially extends.
Fig. 3 is the structural representation that the surface is provided with the bearing pin of axially extended groove.
Fig. 4 is that filling hole is provided with schematic representation.
Fig. 5 hides to cheat schematic representation is set.
Among the figure: 1, inner ring; 2,3,4,5, the outer ring; 6; The groove or the hole of hiding.
Embodiment
In order to improve lubricating often between axle sleeve and the transmission shaft; Reduce maintenance frequency; Improve operating speed and workload, present embodiment provides a kind of axle sleeve that uses like Fig. 1,2, the rocker arm of coal mining machine shown in 3, comprise outer wall 1 and with inwall 2; Its special way is that this inwall 2 is provided with the groove 3 that is used to put oiling agent.
As shown in Figure 2, this groove 3 extending axially along inwall 2.
As shown in Figure 3, groove 3 also can be along the extending circumferentially of inwall 2.
Even in order to ensure what lubricate, groove 3 evenly is arranged on the inwall 2.
Further; In order to improve maintenance efficiency, as shown in Figure 4, can on axle sleeve outer wall 1, offer filling hole 4 in order to the packing lubrication agent; It communicates with groove 3 on the inwall 2; And this filling hole can evenly be provided with a plurality of along groove 3, thus, need not dismantle the filling that axle sleeve can be realized oiling agent.
Certainly on the axle sleeve outer wall, set up a baffle plate; Corresponding to each filling hole 4 place the one internal diameter cylindrical protrusions identical with the internal diameter of filling hole 4 is set all on this baffle plate; When baffle plate covers, can seal filling hole, and be provided with seal ring between baffle plate and the axle sleeve outer wall.
Through the groove 3 of kind of lubricant storage (like solid lubricant) is set on the face that the internal surface at axle sleeve is an inwall 2 with transmission shaft contacts; Increase the loading of oiling agent, prolonged lubricated duration, improved lubricated uniformity; Reduce maintenance frequency, improved operating speed and workload.
As shown in Figure 5, the groove or the hole of hiding are the array-type setting, and adjacent grooves or the distance between the hole of hiding are 2.5 to 6.5mm.The hole of hiding is circular, and its internal diameter is 1 to 2.5mm, and the degree of depth is 1 to 1.5 mm.
The above is merely preferred implementation of the present invention; Only do not represent and be limited by the examples; Other any do not deviate from any change, the modification done under the situation of spirit and principle of the utility model, substitutes, combination, simplify; All should be regarded as the substitute mode equivalent, all be included in protection scope of the present invention with the present invention.
