HDT310 DEG C of hot temperature, also have high fluidity and excellent mechanical performance, TX1 unique harmony in various performances,
High mechanical strength when such as higher dimensional stability, reflow soldering compatibility, high rigidity and high-temperature operation.With other high temperature
Resin is compared, such as polyphtalamide (PPAs) and liquid crystal polymer (LCPs), and the performance of TX1 is more preferably.TX1 also has following
Advantage: mechanical tenacity is high, bonding wire intensity is high and wear resistance is more preferable etc..Therefore had certainly using the bushing that TX1 is produced
The effect of lubrication, moreover it is possible to substitute traditional copper guide sleeve 101, mechanical performance and the wear-resisting pressure resistance for meeting metal guide sleeve 101 are resistance to
High-temperature behavior.
Referring to Fig. 1, dust scraping ring 301 is set to the both ends in first through hole, in the utility model embodiment, guide sleeve
101 include two dust scraping rings 301, and both ends are respectively set there are two cavity receiving dust scraping ring 301 in first through hole, makes guide sleeve
101 and dust scraping ring 301 cooperation it is more compact, prevent dust from entering.Dust scraping ring 301 can strike off the dust in guide post, drop
Self raising flour dirt enters the probability between guide post and bushing (bearing), to promote the service life and dimension of polishing motor guiding mechanism
Protect intensity.
Please continue to refer to Fig. 1, snap ring 401 is additionally provided with outside dust scraping ring 301, in the utility model embodiment, guiding
Set 101 includes two snap rings 401, and snap ring 401 is located on the outside of the both ends in first through hole, connect with 101 card slot of guide sleeve,
The position of snap ring 401 can just resist dust scraping ring 301, prevent dust scraping ring 301 from falling off in the movement of guide post, guarantee guiding
The stability of mechanism cooperates guide post with guide sleeve 101 and is promoted and transferred more smooth.
Referring to Fig. 2, further including dirt-proof boot 501 outside guide sleeve 101, dirt-proof boot 501 can prevent dust from entering guiding
Between column and bushing (bearing), to promote the service life and maintenance intensity of polishing motor guiding mechanism.On dirt-proof boot 501 also
It is provided with zipper 502, the dirt-proof boot 501 for facilitating the dust in timing cleaning dirt-proof boot 501 and more renewing, dirt-proof boot 501 is generally
Using thermoplastic rubber material, such material has elasticity, cold resistance and electrical insulating property.
Referring to Fig. 3, Fig. 3 is mounted guiding mechanism schematic diagram, dirt-proof boot 501 is located at 101 upside of guide sleeve, at this
In utility model embodiment, dirt-proof boot 501 and the top of the guide part 102 of guide sleeve 101 are bolted, detachably,
In the other embodiments of the utility model, the top of the guide part 102 of dirt-proof boot 501 and guide sleeve 101 can also pass through clip
Connection；Two self-lubricating bushings 201 are respectively arranged at the two sides in first through hole, and self-lubricating bushing 201 and guide post cooperation are real
The promotion and decentralization of existing guide post；Two dust scraping rings 301 are respectively arranged at the both ends in first through hole, and dust scraping ring 301 can be scraped
Except the dust in guide post, reduces dust and enter the probability between guide post and bushing (bearing)；Two snap rings 401 are respectively set
In the both ends in first through hole, the outside of dust scraping ring 301 resists the position of dust scraping ring 301, prevents that it from falling off or position becomes
Change.
Referring to Fig. 4, guide post be inside biasing post 601, the outer circle of inside biasing post 601 and the axis of inner hole it is parallel and
It does not coincide, inside biasing post 601 facilitates adjustment using eccentric design, is come with effective counteracting polishing motor housing mismachining tolerance
Installation error, prevent motor install after promoted decentralization hair fastener.
Bushing in guide sleeve 101 realizes the function of self-lubricating, instead of original using bearing made of engineering plastics
Design is lubricated guide post using lubricating grease, it is therefore prevented that lubricating grease is infected with dust, simultaneously because the machine that engineering plastics are excellent
Tool performance, wear-resisting and high-temperature stability can substitute the cooperation between the copper realization of guide sleeve 101 and guide post completely,
Keep the polishing of rail grinding machine more smooth.
Being used cooperatively for dust scraping ring 301 and dirt-proof boot 501, further reduced dust and enters guide post and bushing (bearing)
Between probability, dust scraping ring 301 can scrape the dust in guide post, and dirt-proof boot 501 can completely cut off the dust in air, the two
With the use of the service life and maintenance intensity to promote polishing motor guiding mechanism.
In conclusion a kind of rail grinding machine polishing motor self-lubricating guiding mechanism provided by the utility model and equipment are adopted
With with self-lubricating function and the stronger engineering plastics of comprehensive performance, instead of the copper bushing (bearing) that genuine designs, thus will
The lubrication mechanism of guiding mechanism is changed to self-lubricating by pervious grease lubrication, reduces the attachment of dust, makes guiding mechanism to powder
The susceptibility of dirt reduces.Guiding mechanism increases dirt-proof boot 501 simultaneously, reduces dust in the accumulation of guiding mechanism, solves from source
Certainly dust pollution question makes the fit clearance and relative motion between its guide post and guide sleeve since dust pollution is reduced in work
More smooth, grinding accuracy is higher, polishes also safer.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
