Abstract
The utility model provides a the utility model relates to a high wear-resisting turn-ups oilless bearing, including sleeve pipe and turn-ups, bushing connection is epaxial, the turn-ups with the shaping of bending of sleeve pipe an organic whole is equipped with the through-hole through to centre of a circle direction in the turn-ups, sets up lubricating arrangement in the through-hole, lubricating arrangement includes the graphite rod, the graphite rod with the axle contact. The shaft is subjected to sliding friction, and when cracks are generated on the shaft, graphite powder falling off from the graphite rod can be filled into the cracks to play a lubricating role, so that the damage of the cracks to a bearing coating is reduced, and the service lives of the shaft and the bearing are prolonged.
Description
Technical Field
The utility model relates to a slide bearing especially relates to an improvement to turn-ups oilless bearing.
Background
The flanging oilless bearing is an oilless sliding bearing made of polytetrafluoroethylene, copper powder is sintered on the surface of a steel plate, a polytetrafluoroethylene layer is sintered, the steel plate is rolled into a plate made of a composite material, and then the plate is blanked according to the specification of the sliding bearing, rounded and shaped to form the oilless sliding bearing.
In the actual use, along with the cladding material of sintering along with long-term sliding friction, the cladding material carries on less and less, and bearing lubrication ability descends, and the axle can consequently produce the mar, and the mar can lead to bearing coating aggravation wearing and tearing, causes vicious circle, leads to axle and bearing life to reduce in step.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides a high wear-resisting flanging oilless bearing which prolongs the service life of a bearing and a shaft.
The utility model discloses a following technical scheme realizes: the utility model provides a high wear-resisting turn-ups oilless bearing, includes sleeve pipe and turn-ups, bushing connection is epaxial, the turn-ups with the shaping of bending of sleeve pipe an organic whole, be equipped with the through-hole to centre of a circle direction in the turn-ups, set up lubricating arrangement in the through-hole, lubricating arrangement includes the graphite rod, the graphite rod with the axle contact.
Preferably, the lubricating device further comprises a spring, the spring is connected to the upper end of the graphite rod in the through hole, and the spring tightly presses the graphite rod on the shaft.
Preferably, the lubricating devices are multiple and are uniformly distributed in the flanging.
Preferably, the bottom end of the graphite rod is provided with an arc-shaped groove, and the diameter of the arc-shaped groove is the same as that of the shaft.
Compared with the prior art, the utility model discloses a be equipped with the through-hole to centre of a circle direction in the turn-ups, set up lubricating arrangement in the through-hole, lubricating arrangement includes the graphite rod, the graphite rod with the axle contact. The shaft is subjected to sliding friction, and when cracks are generated on the shaft, graphite powder falling off from the graphite rod can be filled into the cracks to play a lubricating role, so that the damage of the cracks to a bearing coating is reduced, and the service lives of the shaft and the bearing are prolonged.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.
As shown in fig. 1-5: the utility model provides a high wear-resisting turn-ups 31 oilless bearing 3, includes sleeve pipe 32 and turn-ups 31, sintering copper powder and polytetrafluoroethylene layer in the sleeve pipe 32, sleeve pipe 32 connects epaxial 1, and axle 1 is in slide motion in the sleeve pipe 32, turn-ups 31 with sleeve pipe 32 integrative bending shaping, be equipped with through-hole 311 to the centre of a circle direction in the turn-ups 31, set up lubricating arrangement 2 in the through-hole 311, lubricating arrangement 2 includes graphite rod 21, graphite rod 21 with axle 1 contacts. When the shaft 1 is subjected to sliding friction and cracks are generated on the shaft 1, graphite powder falling off from the graphite rod 21 can be filled into the cracks to play a lubricating role, so that the damage of the cracks to the coating of the bearing 3 is reduced, and the service lives of the shaft 1 and the bearing 3 are prolonged.
The lubricating device 2 further comprises a spring 22, the spring 22 is connected to the upper end of the graphite rod 21 in the through hole 311, and the spring 22 tightly presses the graphite rod 21 on the shaft 1. Even if the graphite rod 21 is worn, the graphite rod can be tightly attached to the shaft 1 under the action of the rebounding force of the spring 22, so that the shaft 1 can be kept lubricated continuously.
The lubricating devices 2 are multiple, and the lubricating devices 2 are uniformly distributed in the flanging 31. The shaft 1 can be lubricated in the circumferential direction by using a plurality of the lubricating devices 2.
Graphite rod 21 bottom is provided with arc recess 211, arc recess 211 diameter with axle 1 is the same, arc recess 211 can increase graphite rod 21 with 1 area of contact of axle improves lubricated efficiency.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
