Abstract
The utility model discloses an inner gear ring structure. The inner gear ring structure is characterized by comprising an inner gear ring body. A plurality of transmission components with different levels are successively disposed inside the inner gear ring body. Two adjacent transmission components are in transmission connection. The inner gear ring body is in transmission connection with the transmission components. The transmission components comprise a planet carrier. A sun gear and a planet gear are disposed on the planet carrier. The inner gear ring body is provided two levels of transmission components, a first-level and a second-level transmission components. The inner gear ring structure allows component amount to be reduced, assembly time to be reduced, space to be saved. The same tooth form processing and one-time tooth insertion are only needed to complete a processing course. Processing time is saved and processing cost is reduced.
Description
Technical field
The utility model relates to a kind of ring gear structure.
Background technique
Planetary speed reducer is a kind of broad-spectrum industrial products, its performance can compare favourably with other army's grade speed reducer product, but the price that has technical grade product, is mainly used in the swirl gear of tower crane, can be used as again matching parts for industries such as lifting, excavation, transportation, buildings.
Current most planetary speed reducer, every one-level Gear Planet Transmission all can, with a different ring gear, will increase a body and connect in the middle of two gear rings, by bolt, pin etc., connect location, component are many, space is large, need two parts of processing, workload is large, and efficiency is low, and cost is high.
Summary of the invention
The technical problems to be solved in the utility model is to overcome above-mentioned defect, and a kind of minimizing part number is provided, and reduces installation time, saves space, and processing only needs the same profile of tooth of processing, inserts a tooth and just completes, and saves process time, the ring gear structure cutting down finished cost.
For addressing the above problem, the technological scheme that the utility model adopts is:
A ring gear structure, is characterized in that: comprise internal tooth circle body, internal tooth circle body inside is disposed with some grades of transmitting assembliess, between adjacent transmitting assemblies, is in transmission connection; The described internal tooth circle body transmitting assemblies that is in transmission connection.
Described internal tooth circle body be by 42CrMo material make, the internal tooth circle body of hardness more than HV550.
Described transmitting assemblies comprises planet carrier, and sun gear and planet wheel are installed on planet carrier.
In described internal tooth circle body, be provided with two-stage transmitting assemblies, one-level transmitting assemblies and secondary transmission assembly.
Described one-level transmitting assemblies comprises primary planet carrier, and one-level sun gear and one-level planet wheel are installed on primary planet carrier, and one-level sun gear runs through internal tooth circle body, and one-level planet gear transmission connects secondary transmission assembly.
Described secondary transmission assembly comprises secondary planet frame, and secondary solar gear and secondary planet wheel is installed on secondary planet frame, the secondary solar gear one-level planet wheel that is in transmission connection.
Described primary planet carrier axle is connected with one-level planet wheel, and axle is connected with one-level sun gear.
Described secondary planet frame axle is connected with secondary planet wheel, and axle is connected with secondary solar gear.
Owing to having adopted technique scheme, compared with prior art, the utility model is that two-stage transmitting assemblies is set in internal tooth circle body, and transmitting assemblies comprises sun gear and planet wheel.The utility model internal tooth circle body only needs clamping once, and a gear shaping moulding does not need to process two ring gears, without tool setting clamping repeatedly, economizes at least 30% process time, has saved 20% processing blanking cost.The utility model reduces part number, reduces installation time, saves space, and processing only needs the same profile of tooth of processing, inserts a tooth and just completes, and saves process time, cuts down finished cost.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail simultaneously.
Accompanying drawing explanation
Fig. 1 is a kind of embodiment's of the utility model structural representation.
Embodiment
Embodiment:
As shown in Figure 1, a kind of ring gear structure, comprises internal tooth circle body 4, and internal tooth circle body 4 inside are disposed with some grades of transmitting assembliess, between adjacent transmitting assemblies, be in transmission connection, meanwhile, internal tooth circle body 4 transmitting assemblies that is in transmission connection.
In the present embodiment, described internal tooth circle body 4 be by 42CrMo material make, the internal tooth circle body of hardness more than HV550.
Transmitting assemblies comprises planet carrier, and sun gear and planet wheel are installed on planet carrier.In the present embodiment, in internal tooth circle body 4, be provided with two-stage transmitting assemblies, one-level transmitting assemblies and secondary transmission assembly.
Described one-level transmitting assemblies comprises primary planet carrier 2, and one-level sun gear 1 and one-level planet wheel 3 are installed on primary planet carrier 2, and one-level sun gear 1 runs through internal tooth circle body 4, the one-level planet wheel 3 secondary transmission assembly that is in transmission connection.Secondary transmission assembly comprises secondary planet frame 6, and secondary solar gear 7 and secondary planet wheel 5 is installed on secondary planet frame 6, the secondary solar gear 7 one-level planet wheel 3 that is in transmission connection.
Consider actual needs, primary planet carrier axle is connected with one-level planet wheel, and axle is connected with one-level sun gear.Secondary planet frame axle is connected with secondary planet wheel, and axle is connected with secondary solar gear.
The utility model is that two-stage transmitting assemblies is set in internal tooth circle body, and transmitting assemblies comprises sun gear and planet wheel.The utility model internal tooth circle body only needs clamping once, and a gear shaping moulding does not need to process two ring gears, without tool setting clamping repeatedly, economizes at least 30% process time, has saved 20% processing blanking cost.
Above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit, although executing example with reference to previous examples has been described in detail the utility model, those of ordinary skill in the art is to be understood that, it is modified according to the technological scheme that can record aforementioned each embodiment, or its part technical characteristics is equal to replacement, and these modifications or replacement, do not make the essence of appropriate technical solution depart from spirit and the category of technical solutions of the utility model.
