A transmission for engineering machinery with high speed ratio mainly comprises an input block, a middle block, a transitional block and an output block, wherein, the input shaft of the input block and the transitional shaft of the transitional block are arranged in the same line, and the intermediate shaft of the middle block and the output shaft of the output block are arranged in the same line; the axis of the input shaft and that of the output shaft are parallel with each other; an input transmission gear is fixedly connected to the input shaft; a middle transmission gear and a middle gear are fixedly connected to the intermediate shaft; a transitional gear and a transitional transmission gear are fixedly connected to the transitional shaft; an output transmission gear is sleeved on the output shaft through a rolling bearing; and at least a shift mechanism is mounted on the output shaft. The utility model has the advantages of simple and compact structure, convenient and flexible operation, small overall size, light weight, advanced technical indicators, reliable use, convenient installation and maintenance, low cost, and high standardization, serialization and generalization degrees of main parts, and can meet the requirements of application condition of engineering machinery, especially pavement maintenance machinery.
Description
Technical field
The utility model relates to main engineering machinery speed changer, especially a kind of large speed ratio engineering machinery speed changer by meshed transmission gear.
Background technique
The speed changer that engineering machinery is used mostly with parallel input, be output as many, which comprises at least input shaft and output shaft, and axle is gone up socket or that be connected, intermeshing driving gear separately, for the speed changer that requires multiple transmission agency, can structurally increase parts, as clutch etc.That is to say,, can increase the complexity of structure, increase cost simultaneously, increase volume along with the function increase of speed changer, unfavorable to the popularization of using.And for the comparatively simple speed changer of structure, the power of not only function singleness, and transmission is less, can't satisfy the needs of high-power transmission.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provides a kind of simple in structure, compact, and handiness is flexible, boundary dimension is little, in light weight, and technical order is advanced, uses reliable, installation and maintenance are convenient, the large speed ratio engineering machinery speed changer that cost is low.It is mainly by input block, intermediate member, and transition member and output block are formed, and the input shaft of described input block and the transition axis of transition member are arranged on the same straight line; And the output shaft of the jack shaft of intermediate member and output block is arranged on the same straight line, the axis of input shaft and output shaft parallel axes.
Be consolidated with input drive gear on the described input shaft, on jack shaft, be consolidated with intermediate drive gear and intermediate gear respectively, on transition axis, be consolidated with transition gear and transition driving gear, on output shaft, then be set with output drive gear, a gearshift mechanism then is installed on the output shaft at least by rolling bearing.
Described gearshift mechanism comprises that one fixedly is connected in toothholder and on the output shaft and is connected in middle toothholder on the jack shaft, the one tooth cover that links to each other with hydraulic jack and position limit switch is arranged between toothholder, middle toothholder and the output drive gear and can move left and right meshes in twos, realizes top gear, bottom gear and neutral.
Working principle described in the utility model is: when the tooth cover with jack shaft, when output shaft is connected, the power of input is directly passed to output shaft output after slowing down by input drive gear and intermediate drive gear one-level, the output of realization top gear, intermediate gear and transition gear, transition driving gear and output drive gear engagement idle running at this moment; When the tooth cover with output shaft, when output drive gear is connected, the power of input is exported after by gear input drive gear and intermediate drive gear, intermediate gear and transition gear, transition driving gear and three grades of decelerations of output drive gear, realizes bottom gear output.When the tooth cover only meshes with output shaft, input drive gear and intermediate drive gear, intermediate gear and transition gear, transition driving gear and output drive gear engagement idle running at this moment, the unpowered output of output shaft, this moment, gearbox was in neutral gear position.
The utility model compared with prior art, have simple in structure, compact, handiness is flexible, and boundary dimension is little, in light weight, and technical order is advanced, use reliable, installation and maintenance are convenient, and cost is low, " three change " degree height of main parts size, can satisfy engineering machinery, particularly the characteristics such as demand of maintenance of surface machinery applying working condition.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in the accompanying drawing 1, it mainly contains input block the utility model, intermediate member, transition member and output block are formed, and the input shaft 1 of described input block and the transition axis 6 of transition member are arranged on the same straight line; And the output shaft 8 of the jack shaft 4 of intermediate member and output block is arranged on the same straight line, the axis of input shaft 1 and output shaft 8 parallel axes.
Be consolidated with input drive gear 2 on the input shaft 1 described in the utility model, on jack shaft 4, be consolidated with intermediate drive gear 3 and intermediate gear 11 respectively, on transition axis 6, be consolidated with transition gear 5 and transition driving gear 7, on output shaft 8, then be set with output drive gear 9, a gearshift mechanism then is installed on the output shaft 8 at least by rolling bearing.Gearshift shown in the drawings comprises that one fixedly is connected in toothholder and on the output shaft 8 and is connected in middle toothholder on the jack shaft, the one tooth cover 10 that links to each other with hydraulic jack 13 and position limit switch 12 is arranged between toothholder 14, middle toothholder 15 and the output drive gear 9 and can move left and right meshes in twos, realizes top gear, bottom gear and neutral.
Working principle described in the utility model is: when tooth cover 10 is connected with jack shaft 4, output shaft 8, the power of input is directly passed to output shaft 8 outputs after slowing down by input drive gear 2 and intermediate drive gear 3 one-levels, the output of realization top gear, this moment, intermediate gear 11 meshed idle running with transition gear 5, transition driving gear 7 with output drive gear 9; When tooth cover 10 is connected with output shaft 8, output drive gear 9, the power of input is exported after by input drive gear 2 and intermediate drive gear 3, intermediate gear 11 and transition gear 5, transition driving gear 7 and 9 three grades of decelerations of output drive gear, realizes bottom gear output.When 10 in tooth cover during with output shaft 8 engagements, input drive gear 2 and intermediate drive gear 3, intermediate gear 11 dally with output drive gear 9 engagements with transition gear 5, transition driving gear 7 at this moment, the unpowered output of output shaft, this moment, gearbox was in neutral gear position.
The utility model is a kind of novel large speed ratio engineering machinery speed changer, and 2 forward gears, 1 neutral are arranged, and the forward gear speed ratio is 1.5854 and 21.7926.
