The effect of support roller 4 mainly is to cooperate reductor that tank body is formed a stable three-point support structure, and under the drive of reductor, tank body can be realized the positive and negative rotation of adjustable speed simultaneously.For guaranteeing the steady running of tank body, necessarily require 4 pairs of tank bodies of support roller that the good supporting effect is arranged, but the support roller assembly of prior art is when heel and toe wear takes place in tank body raceway, support roller 4, because roller bearing 3 can't be adjusted the gap between support roller 4 and raceway, be that support roller 4 outer edge surfaces 40 remain constant with the contact site of raceway and the distance in bearing pin 2 axle center, can not increase and to reduce, make raceway can not contact well with support roller 4, cause the tank body shake easily, influence the normal operation of vehicle.
The utility model content
The trucd mixer that the utility model will solve prior art is with the technical problem that can't adjust the gap between support roller and raceway in the support roller assembly, a kind of improved trucd mixer support roller assembly is provided, to realize, guarantee that the tank body raceway well contacts with support roller to the adjustment of the gap between support roller and raceway.
The utility model also provides a kind of trucd mixer with the utility model trucd mixer with the support roller assembly.
The technical solution of the utility model is as follows:
A kind of trucd mixer support roller assembly, comprise roller bracket, be fixedly connected on described roller bracket bearing pin, be located at the support roller of described bearing pin by bearing holder (housing, cover), described bearing is a self-aligning bearing.
Trucd mixer of the present utility model support roller assembly, preferred, described self-aligning bearing is a self-aligning roller bearing.
Trucd mixer of the present utility model support roller assembly, preferred, fixed installation is useful on the outer back-up ring that prevents lateral shift between support roller and the self-aligning bearing on the inner face of described support roller both sides shoulder.
Trucd mixer of the present utility model support roller assembly, preferred, described self-aligning bearing both sides are provided with in order to prevent described self-aligning bearing inner shield ring in axial sliding.
Trucd mixer of the present utility model support roller assembly, preferred, described bearing pin is connected in described roller bracket by nut.
Trucd mixer of the present utility model has trucd mixer of the present utility model support roller assembly.
The beneficial effects of the utility model are, trucd mixer of the present utility model support roller assembly is a kind of novel support roller assembly with regulatory function, guarantee that the tank body raceway well contacts with support roller.Convenient production in manufacture process guarantees that the tank body raceway can effectively contact with support roller.In user's use,, can guarantee that also tank body effectively contacts with raceway even raceway or support roller wear and tear.Trucd mixer of the present utility model support roller assembly also has novel structure, convenient and practical characteristics.
Description of drawings
Fig. 1 is the vertical profile schematic diagram of the trucd mixer of prior art with the support roller assembly;
Fig. 2 is the vertical profile schematic diagram of the trucd mixer of the utility model preferred embodiment with the support roller assembly;
Fig. 3 is the assembling schematic diagram of the trucd mixer of the utility model preferred embodiment with the support roller assembly.
The specific embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be pointed out that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The trucd mixer of the utility model embodiment has the trucd mixer support roller assembly of the utility model preferred embodiment.
As shown in Figures 2 and 3, the trucd mixer of the utility model embodiment support roller assembly 15, comprise roller bracket 1, bearing pin 2 and nut 7, bearing pin 2 is fixedly connected on roller bracket 1 by nut 7, the structure of above-mentioned parts, select for use and annexation etc., all can be identical with the corresponding component in the prior art support roller assembly.
As shown in Figure 2, the trucd mixer of the utility model embodiment support roller assembly 15, support roller 9 is sheathed on bearing pin 1 by self-aligning bearing 8, and the self-aligning bearing 8 in the utility model preferred embodiment is a self-aligning roller bearing.Self-aligning roller bearing is to be between the outer ring of sphere at inner ring that two raceways are arranged and raceway, and the bearing of barrel shaped roller is housed.Self-aligning roller bearing has two row rollers, mainly bears radial load, also can bear the axial load of either direction simultaneously.Higher radial capacity is arranged, be specially adapted to work under heavy duty or the oscillating load, but can not bear pure axial load.Such bearing outer ring ball track is a sphere shape, so its aligning performance is good, and can compensating coaxial degree error.The endoporus of self-aligning roller bearing can be respectively cylindrical bore or tapered bore.
Trucd mixer of the present utility model support roller assembly 15, its self-aligning bearing also can be the self-aligning bearing of the other types except that self-aligning roller bearing.
As shown in Figure 2, the trucd mixer of the utility model embodiment support roller assembly 15, the inner face of support roller 9 both sides shoulders and both sides, self-aligning bearing 8 outer ring end face are respectively arranged with outer back-up ring 17.Two outer back-up rings 17 are fixedly mounted on the inner face of support roller 9 both sides shoulders accordingly, so that between support roller 9 and the self-aligning bearing 8 lateral shift does not take place.
As shown in Figure 2, the trucd mixer of the utility model embodiment support roller assembly, self-aligning bearing 8 is provided with inner shield ring 16 with the both sides of the junction of bearing pin, the madial wall of inner shield ring 16 is close to the sidewall of self-aligning bearing 8 inner rings, the lateral wall of inner shield ring 16 is close to the madial wall of roller bracket 1, so that support roller 9 can not endwisely slip with respect to bearing pin 2.
As shown in Figure 3, after support roller assembly 15 finishes by assembling shown in Figure 2, be fixed on the mounting plate 19 that has an angle of inclination, the support roller 9 and the raceway 14 of tank body 13 are fitted.
As shown in Figures 2 and 3, the trucd mixer of the utility model embodiment and support roller assembly 15 thereof, the effect of support roller 9 mainly is to cooperate 11 pairs of tank bodies of reductor 13 to form a stable three-point support structure, and under the drive of reductor 11, tank body 13 can be realized the positive and negative rotation of adjustable speed simultaneously.For guaranteeing the stability running of tank body, 9 pairs of tank bodies of support roller have the good supporting effect.Because the aligning effect of self-aligning bearing 8, can adjust the gap of 14 of support roller 9 and raceways, be that support roller 9 outer edge surfaces can change relatively with the contact site of raceway 14 and the distance in bearing pin 2 axle center, can be reduced by weight, when weight disappears, upspring, make raceway can contact well, even when heel and toe wear takes place for tank body raceway 14, support roller 9 with support roller, also can prevent the tank body shake, thereby guarantee the normal operation of vehicle.
Above-described only is preferred possible embodiments of the present utility model; described embodiment is not in order to limit scope of patent protection of the present utility model; therefore the equivalent structure done of every utilization specification of the present utility model and accompanying drawing content changes, and in like manner all should be included in the protection domain of the present utility model.
