Description
Technical field
The utility model relates to a kind of structure of driving axle of forklift, specifically a kind of driving axle of forklift structure with step trough.
Background technology
Driving axle of forklift is control fork truck fork truck load-carrying and driving driving the effect in fork truck system.In existing driving axle of forklift structure, due to the second bearing between axle housing and wheel hub identical with the outer circularity of the second oil sealing (being 125), friction force between second bearing and the second oil sealing is larger, therefore when real work, in order to reduce the friction force between the second oil sealing and the second bearing, as shown in Figure 2, prior art adopts to set up foundry goods ring between the second bearing and the second oil sealing.Above-mentioned prior art tooling cost is higher, installs and keeps in repair more inconvenient, being therefore necessary to improve.
Summary of the invention
The purpose of this utility model is the weak point in order to overcome background technology, and provides a kind of driving axle of forklift structure with step trough.
To achieve these goals, the technical solution of the utility model is: with the driving axle of forklift structure of step trough, comprise semiaxis, be installed on the axle housing outside semiaxis, be installed on the wheel hub at axle housing two ends, be installed on the brake hub outside wheel hub, be installed on the drg inside brake hub, described wheel hub is connected by semiaxis bolted with between semiaxis, be fastenedly connected by boss bolt between wheel hub and brake hub, from front to back the first circular nut is installed successively between described wheel hub inside front ends and axle housing, second circular nut, first lining, clutch shaft bearing, first oil sealing is installed outside the first lining and between wheel hub, fit tightly inside first oil sealing with outside the first lining, fit tightly with wheel hub inside front ends outside first oil sealing, it is characterized in that: inside described wheel hub, between rear end and axle housing, be provided with the first step trough and the second step trough from front to back successively, first step trough is provided with the second bearing, second step trough is provided with the second oil sealing and the second lining, outside described second oil sealing with wheel hub inside rear end fit tightly, fit tightly inside second oil sealing with outside the second lining, be connected with axle housing inside second lining.
The utility model can make the second oil sealing and the second bearing directly not come in contact, and install and keep in repair convenient, tooling cost is lower.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of prior art.
1-semiaxis in figure, 2-axle housing, 3-wheel hub, 4-brake hub, 5-drg, 6-half axle bolt, 7-takes turns, hub bolt, 8-first circular nut, 9-second circular nut, 10-first lining, 11-second lining, 12-clutch shaft bearing, 13-second bearing, 14-first oil sealing, 15-second oil sealing, 16-first step trough, 17-second step trough, 18-foundry goods ring.
Detailed description of the invention
Describe performance of the present utility model in detail below in conjunction with accompanying drawing, but they do not form to restriction of the present utility model, only for example.Make advantage of the present utility model clearly and easy understand by explanation simultaneously.
Accompanying drawings is known: with the driving axle of forklift structure of step trough, comprise semiaxis 1, be installed on the axle housing 2 outside semiaxis 1, be installed on the wheel hub 3 at axle housing 2 two ends, be installed on the brake hub 4 outside wheel hub 3, be installed on the drg 5 inside brake hub 4, be fastenedly connected by half axle bolt 6 between described wheel hub 3 and semiaxis 1, be fastenedly connected by boss bolt 7 between wheel hub 3 and brake hub 4, between described wheel hub 3 inside front ends and axle housing 2, first circular nut 8 is installed from front to back successively, second circular nut 9, first lining 10, clutch shaft bearing 12, first oil sealing 14 is installed outside first lining 10 and between wheel hub 3, fit tightly inside first oil sealing 14 with outside the first lining 10, fit tightly with wheel hub 3 inside front ends outside first oil sealing 14, it is characterized in that: inside described wheel hub 3, between rear end and axle housing 2, be provided with the first step trough 16 and the second step trough 17 from front to back successively, first step trough 16 is provided with the second bearing 13, second step trough 17 is provided with the second oil sealing 15 and the second lining 11, outside described second oil sealing 15 with wheel hub 3 inside rear end fit tightly, fit tightly inside second oil sealing 15 with outside the second lining 11, be connected with axle housing 2 inside second lining 11.
As shown in Figure 2, the effect of foundry goods ring 18 prevents the second oil sealing from directly contacting with the second bearing, thus avoid producing friction force between oil sealing and bearing, existing Drive axle housing design needs to install foundry goods ring, which raises productive costs, meanwhile, paying of man power and material when drive axle is installed is turn increased.
The utility model changes the specification of the second oil sealing into 100X130X12 by 100X125X10, meanwhile, changes the endoporus of wheel hub into 130 by 125.Owing to having monolateral step between the endoporus of wheel hub and the second oil sealing, this step just limits the contact of oil sealing and bearing.The position of oil sealing is made to have had positioning datum.
The utility model is reasonable in design, and structure is simple, accurately can locate, the second oil sealing and the second axle can be made to produce and hold isolation, directly not come in contact the second oil sealing, and meanwhile, the utility model is installed and keeped in repair more simple and convenient.Other unaccounted part all belongs to prior art.
