Utility model content
In view of the above-mentioned problems of the prior art, the utility model provides a kind of engineering machinery cast type guide wheel,
Performance is improved, performance meets the requirements of the engineering machinery such as large-tonnage excavator, bull-dozer.
To achieve these goals, the utility model include wheel body, guide wheel axle sleeve, straight pin, wheel shaft, float grease seal and
Axle bed；Wherein, guide wheel axle sleeve interference fit press-in wheel endoporus；It is sealed between wheel body and axle bed using float grease seal；Wheel shaft mistake
Axle sleeve, axle bed are fixed on the both ends of wheel shaft；Axle bed is fixed with wheel shaft by straight pin.
Further, guide wheel axle sleeve practicality high-tensile strength brass is material.
Further, O-ring is further included, wheel is sealed with axle bed gap by O-ring.
Further, axle bed uses cast steel identical with wheel body.
Further, intracoelomic cavity and wheel shaft are taken turns and is injected with lubricating oil with guiding wheel shaft set gap location.
Further, lubricating oil forms oil film.
Further, O-ring is rubber material.
The prior art is compared, the utility model possesses the characteristics of following：
1. lubricating oil injection wheel inner cavity, wheel shaft and axle sleeve gap location, wheel body are relatively rotated with respect to wheel shaft, centre forms oil
Film reduces friction.
2. axle bed uses cast steel identical with wheel body, axle bed intensity, toughness are greatly improved, so as to improve entire wheel
Performance.
3. guide wheel axle sleeve practicality high-tensile strength brass is material, the service life is improved.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
In figure：1. wheel body, 2. axle sleeves, 3. straight pins, 4. wheel shafts, 5.O type circles, 6. floating sealing assemblies, 7. axle beds.
