Description
Technical field
The utility model relates generally to a kind of riding wheel apparatus of concrete mixer truck, belongs to concrete central mix plant technical field.
Background technology
The tank body of concrete mixing and transporting car is the mechanical part loading ready-mixed concrete, it is by the rotation of self and the acting in conjunction of tank body internal helical blades, complete the specific function of pulverizing, ready-mixed concrete, because its volume and weight is all comparatively large, only support by the axial rotation support roller at tank body two ends at present, support roller is greatly stressed, the many dust of working environment, need the lubrication guaranteeing that support roller is good for a long time, reliable radial support, guarantee that tank body rotates reliable, working properly.At present, support roller adopts grease lubrication, and after working long hours, temperature raises, and causes grease thinning, leaks, works long hours, make support roller be in dry condition.
Summary of the invention
Goal of the invention:
The utility model is intended to the riding wheel apparatus proposing a kind of concrete mixer truck, its objective is that after working long hours, temperature raises, and causes grease thinning, leaks, makes support roller be in the problems such as dry condition in order to solve support roller employing grease lubrication.
Technical scheme:
A riding wheel apparatus for concrete mixer truck, this riding wheel apparatus comprises: floating seal, support; It is characterized in that: support is provided with axle; Floating seal seat is arranged on axle; Bearing is arranged on axle, and support roller is arranged on bearing; Floating seal half is rotated with support roller, and second half and floating seal seat maintain static, and forms movable sealing; Axle, floating seal seat, form bearing lubrication chamber between floating seal and support roller, axle is provided with oil inlet passage.
Support roller can rotate.
Floating seal seat is fixed by a pin on axle.
Plug screw is arranged on the oil filler point of axle.
Advantage and effect:
The utility model has the following advantages and beneficial effect:
(1) adopt floating seal mode, by oil lubrication, be applicable to working long hours;
(2) floating seal mode is adopted, can effective sealing, prevent dust from entering;
accompanying drawing illustrates:
Fig. 1 is the utility model structural representation.
Description of reference numerals:
1. axle; 2. floating seal seat; 3. floating seal; 4. support roller; 5. bearing; 6. plug screw; 7. pin 8. support.
detailed description of the invention:
The utility model proposes a kind of riding wheel apparatus of concrete mixer truck, as shown in fig. 1, this riding wheel apparatus comprises: floating seal 3, support 8; It is characterized in that: axle 1 is installed on support 8; Floating seal seat 2 is arranged on axle 1; Bearing 5 is also arranged on axle 1, and support roller 4 is arranged on bearing 5; Floating seal 3 half is rotated with support roller 4, and second half and floating seal seat 2 maintain static, thus forms movable sealing; By axle 1, floating seal seat 2, between floating seal 3 and support roller 4, form bearing lubrication chamber, axle 1 is also provided with oil inlet passage.
Above-mentioned support roller 4 can rotate.
Above-mentioned floating seal seat 2 is fixed on axle 1 by pin 7.
Plug screw 6 is arranged on the oil filler point of axle 1, opens during oiling, after having noted oil, is screwed into oil filler point, plays sealing process.
Conclusion:
Support roller of the present utility model adopts floating seal mode, resistance to compression oil lubrication, ensures lubricant effect, extends the service life of support roller, often need not refuel maintenance; Adopt floating seal mode can the tightness of available protecting internal structure, prevent dust from entering.
